Wisdom Returns 

            Wisdom, a female Laysan albatross and the world's oldest known, banded bird, returned to Midway Atoll National Wildlife Refuge on 11/27/24 and was soon seen incubating an egg. When she was banded in 1956, she was conservatively estimated to be five years old – the earliest age that the Laysan albatross reach sexual maturity. This corresponds to a hatching date of 1950-51 at the very latest, so she is at least 74 years old and could be even older!

            Of the more than 250,000 birds banded since biologist Chandler Robbins banded Wisdom in 1956, the next oldest bird known is a mere 52 years old, according to the U.S. Fish and Wildlife Service. 

            The US Geological Survey has tracked Wisdom since she was first tagged and estimates that she has flown over 3,000,000 miles since 1956, or approximately 120 times the circumference of the Earth. Over this time, the USGS has replaced her tag six times.

Snowy Owl Update – A Big Influx!

            Nick Anich in Ashland posted the following on 12/8: “Super quick check of the lake [Lake Superior] netted 6 Snowy Owls – 2 on the ice shelf at Maslowski [Beach], 4 at Bayview Park . . . Most of these birds are far out [on the bay] during the day, but start to come inland, move around, and sit around the lakeshore around 4 PM.”

            In my last column, the numbers reported then suggested an average year. But these new numbers in Ashland alone suggest a possible irruption year. 

            I’ll keep you posted as more are reported. In the meantime, a trip to Ashland to look for snowies might be in order!

 

Ice-Up

            From Woody Hagge: “Foster Lake [in Hazelhurst] froze over entirely on Tuesday, December 3. Earlier than I imagined given the warm autumn.” 

            Woody began keeping records in 1976 for ice-up, and has now compiled 49 years of data on ice-up and ice-out dates for 38-acre Foster Lake. The average date for ice-up on Foster is now Nov. 27. 

            Meanwhile, the Manitowish River below our house finally froze completely on 12/12 after our first truly cold night when we hit -14°F.

 

A Short History of Evening Grosbeaks

            Every species of plant or animal has a story, but the story of evening grosbeaks is particularly unusual because they are relatively recent arrivals in Wisconsin – they’re an immigrant, though a native one. Until the mid-1800s, they were a common western bird, but were very uncommon east of the Rockies and rare east of Mississippi River. They appeared in the Midwest and east of the Great Lakes in a notable winter irruption in 1854-55, followed by sporadic irruptions over many decades, until finally reaching Rhode Island in the winter of 1910–1911. 

            By the 1920s, they had been recorded in winter in all 48 contiguous states and were a regular winter visitor in New England. Their expansion was largely attributed to the widespread planting of the lowly box elder in prairie windbreaks and as an ornamental in northeastern cities. The seeds of box elder persist on the tree through winter, allowing winter flocks of evening grosbeaks from the west to now overwinter in the east. Combine the box elder seeds in winter with huge spruce budworm outbreaks in the summer, and evening grosbeaks became relatively common from the Pacific Ocean to the Atlantic.

            In fact, they became abundant. In the East, from about 1965 to the mid-’90s, huge numbers were common every winter all the way down to the Carolinas and sometimes farther south. Literally everyone who fed birds during that timeframe remembers having such large flocks at their feeders that many wished they’d go away, because they ate enormous quantities of bird seed and were bullies at the feeders. 

            But beginning in 1995, winter numbers in the eastern United States crashed. A 2008 study by the avian conservation group Partners in Flight found that evening grosbeaks no longer appeared at half of their historical sites, and that flock sizes had shrunk by more than a quarter. And the numbers kept shrinking. According to a 2019 article in the journal Science, the species suffered a 92 percent population reduction. 

            The American Bird Conservancy currently says the evening grosbeak is experiencing the steepest decline of any land bird in the continental United States and Canada.

            The question, of course, is why. Surprisingly, relatively little is known of the species' life history, because during the breeding season, it’s secretive. Its courtship occurs with little song or display, and its nest is placed high in a tree in mostly northern boreal forests, making it very difficult to study. As a result, the reasons for its decline have been hard to pinpoint. 

            One of the very likely factors, however, is the chemical spraying for spruce budworms, which reduces the abundance of the budworms and other nearby insect prey. In high budworm population years, the caterpillars offer a feast for evening grosbeaks and other boreal birds, and likely contribute to higher reproductive success. Whether government and private timberland owners who routinely spray budworm “hotspots” with pesticides and other biological agents will reduce their spraying is an open question.

            Take heart – there is some good news. You may recall that during the winter of 2022–2023, many people, including Mary and me, reported good numbers of evening grosbeaks coming to their feeders. This was one of the biggest years since the decline started in the ’90s. 

            Did that year presage a significant recovery? Well, the jury is still out. Researchers say that evening grosbeak populations in southern Quebec and the Gaspé Peninsula appear to be growing, while populations south of that appear to be in decline.

            Evening grosbeaks once nested, albeit uncommonly, in northern Wisconsin. Mary and I used to have a pair of evening grosbeaks nesting somewhere near our home in Manitowish because we’d see juvenile birds at our feeders in the summer. I don’t recall the year we stopped seeing them, but it was sometime in the 1990s. Whether they will ever nest again in our area is truly unknown. Right now, we’d be very happy to just have them visit in winter.

Wisconsin Frog and Toad Survey Results from 2023

            The nine species of frogs and toads that breed in our area are all now in full hibernation – wood frogs, spring peepers, chorus frogs, and gray treefrogs are underground in small depressions in upland forests where they freeze nearly solid; green frogs, bullfrogs, mink frogs, and leopard frogs are on the bottom of lakes and rivers laying on the sediments or in the muck and leaf debris, and American toads are buried below the frost line in loose soil. 

            So, the question every year is did they have a successful breeding season? To answer this, the WDNR began an annual volunteer frog and toad survey in 1984 because of concerns about declines in some frog species. Plus, frogs are good indicator species for the quality of habitats where they are found, so their numbers offer a “canary in the coal mine” perspective on environmental changes that may be occurring.

            Mary and I have run one of the survey routes in western Vilas County since 1988 – 36 years now. We are just one of around 150 routes throughout the state. 

            The results are tabulated and sent to us in the late fall of the following year. So, here are the general findings for 2023: Of the twelve frog species found in the entire state (again, only 9 of these breed in the Northwoods), eight showed an increase in percent occurrence in 2023 from 2022 levels. These were the American toad, Blanchard’s cricket frog, boreal chorus frog, Cope’s gray treefrog, gray treefrog, northern leopard frog, spring peeper, and wood frog. Four species were below the previous year’s occurrence levels: American bullfrog, green frog, mink frog and pickerel frog. 

            Since these numbers change from year to year based on weather conditions – a wet spring, for instance, obviously offers far more breeding opportunities for frogs than a really dry one – what does 2023 really tell us?

            Very little really. The key, like in all wildlife surveys, is to look at long-term data for trends, rather than jump to conclusions based on just a year or two of observations.

            With that in mind, I recommend the purchase of a mammoth book that came out in 2022 – Amphibians and Reptiles of Wisconsin, edited by Joshua Kapfer and Donald Brown, published by the University of Wisconsin Press. At 1,173 pages and weighing nine pounds, you won’t be carrying it in your back pocket as a field guide. But you will be referring to it incessantly for its comprehensive job of summarizing the known research on all of our Wisconsin amphibians and reptiles. 

            So, for instance, how are spring peepers doing in Wisconsin? In a nutshell, “Despite reports from Wisconsin in the 1980s and 1990s of a small but statistically significant decline, recent Wisconsin Frog and Toad Survey data suggest that populations are stable to slightly increasing.”

            The book will set you back $75, but if you want to know the population status of any of these species, how they’re adapted to the winter, what their breeding habitat is, who are their predators and their prey – and on and on – this is the book to buy.   

 

Poetry 

            I’ve recently published my second book of poetry, The Birds are Singing in the Snow. The 90 poems celebrate the extraordinary diversity of life in the Northwoods and explore how we’re to honor the gift we’ve been given of living here (see www.manitowishriverpress.com). I want to also recommend three books of poetry that are to my mind beautiful, profound, and well worth your time: Wendell Berry’s This Day: Collected and New Sabbath Poems; Mary Oliver’sDevotions: The Selected Poems of Mary Oliver; and Joy Harjo’s When the Light of the Word was Subdued, Our Songs Came Through, an edited anthology of Native Nations poetry. 

 

Thought for the Week and for the Ending of 2024 

            “Those who dwell, as scientists or laymen, among the beauties and mysteries of the earth are never alone or weary of life. Whatever the vexations or concerns of their personal lives, their thoughts can find paths that lead to inner contentment and to renewed excitement in living. Those who contemplate the beauty of the earth find reserves of strength that will endure as long as life lasts. There is symbolic as well as actual beauty in the migration of the birds, the ebb and flow of the tides, the folded bud ready for the spring. There is something infinitely healing in the repeated refrains of nature – the assurance that dawn comes after night, and spring after the winter.” – Rachel Carson (from The Sense of Wonder)

Losing Loons

            From Walter Piper’s blog post (https://loonproject.org/2024/11/18/not-giving-up/) on 11/18/24: “Wisconsin breeding [loon] pairs fledge 26% fewer chicks now than they did 25 years ago. Our more limited data from Minnesota indicate low breeding success there as well. 

            “But . . . loss of chicks while under their parents' care is less of an issue than the escalating die-off of young adult loons after they leave the breeding grounds. Survival in this later stage of the life history is down over 80%. Of 99 chicks that we banded in 1998, 1999, and 2000, we had resighted 38 (38%) as adults by 2004. In contrast, we have reobserved as adults only 9 of 155 chicks (6%) banded between 2018 and 2020.

            “These young loons are also the future. From their ranks come replacements for breeders that die each year. So young adults . . . are essential to population stability.

            “We have lost several of our traditional territories in Wisconsin during the past few years. We did not find breeding pairs on Bridge, East Horsehead, Hildebrand, Miller, Oneida-East, Pickerel-North, Tom Doyle, Swamp, or Muskellunge (Lincoln Co.) in 2024 . . . Still, there has not been a wholesale loss of territorial pairs in the Upper Midwest, which one might have expected from the high mortality of young adults. So while we have far fewer young nonbreeders milling around, the decline in the territorial loon population is, as yet, small.

            “Thus, the loon population might be more resilient than we had feared. We have long known that the majority of young loons that return to the breeding grounds never settle on a territory. Perhaps the die-off of young adults merely reduces their number to those few that would normally claim territories anyway. It is a hopeful thought!

            “I am connecting with water quality specialists in Wisconsin and Minnesota in hopes of learning why we are losing water clarity in July, which harms loon chicks. And I am searching feverishly – both on the breeding grounds and in Florida, where most of our birds winter – for the cause of the high mortality in young adults. These are not quixotic quests. I feel that people who love loons in the Upper Midwest will step up and help them if we can pinpoint the factors that endanger their population.”

            If you care about loons, and you are looking for an excellent scientific study to donate to, may I recommend Walter Piper’s efforts - https://loonproject.org/donate/.

Snowy Owl Numbers

            Ryan Brady, DNR conservation biologist from Washburn, tracks the number of snowy owl sightings in Wisconsin each year. For the winter of 2023-24, he tallied 24 individual snowy owls in the state, the lowest number in the last decade.

            In 2022-23, for comparison, 36 snowies were documented in the state, while 140 were recorded in 2021-22. More than 200 were documented in the big irruption years of 2013, 2014, and 2017.

            As of November 25, 11 owls have been reported statewide, including several along the Great Lakes shorelines and others at inland locations such as Wausau and Eau Claire. This fall’s total is below that of a typical irruption year, suggesting it may be an “average” year. More should be arriving, but typically not here in the Northwoods – we’re the wrong habitat. They typically are seen at large lakefronts (Lake Michigan, for instance), farm fields and even wide open developed areas like airports.

            "Our last irruption was 2021-22,” according to Brady. “If the approximately four- to five-year cycle holds up – and that’s a big if – then next year or the year after should see a higher pulse of birds."

eBird map of snowy owl sightings as of 11/28/24

            But . . . you never know. Ryan just shared (11/28) a photo of a snowy perched on top of the roof of an Arby’s in Ashland. If the snowies are already staking out the fast food joints, it might be a banner year after all.

Bear Hunt Totals

            Hunters registered 4,285 black bears during the 2024 Wisconsin bear hunting season, according to preliminary data released by the Department of Natural Resources.

            The five-week season was marked by a high statewide success rate of 37%, up from 24% last year and the 31% five-year rate. The 2024 bear kill exceeded the statewide target by 11% and represents a 46% year-over-year increase.

            The last two seasons were substantially different primarily due to a huge acorn crop in 2023, according to DNR reports. The natural food source reduced the effectiveness of bait placed by hunters last year, illustrating just one of the many reasons why hunt numbers for any species can vary from year to year.  

            Wisconsin has an estimated 23,000 black bears.

Gear Ideas for Christmas

            I’m always advocating for people to upgrade their binoculars from that old non-waterproof, heavy pair that was handed down to you when you were a kid. So, what to know? Model numbers on binoculars essentially tell you their magnification power and the size of the objective lens (basically how much light the lens lets in). In 8x42 binoculars, for example, “8” is the magnification power and “42” is the diameter in millimeters of the objective lenses. A ratio of magnification to objective lens of at least 1:5 is what you want. Too small a ratio and less light enters the binocs, which makes for poorer viewing.  

            An eight-power magnification is generally ideal, because going any higher, like to a 10 power, makes for a heavier binocular that is harder to hold steady, and which also has a smaller field of view for actually finding that little warbler high in that hemlock that is making you crazy.

            You can certainly buy more compact binocs that are lighter to carry – Mary and I each have a pair of these, too (8x28). But the quality suffers because less light enters the lens.

            Make sure the binocs are waterproof, fog-proof, and rubber coated. Now you can take them out in your kayak or fishing boat and not worry about dropping them in the water. 

            Also, be sure the pair has adjustable eyepieces that twist out. If you wear glasses, you want the eyepieces twisted in, which keeps the binocs at the right distance from your eye. If you don’t wear glasses, you want the eyepieces twisted out, otherwise you may only see blackness because the lenses are too close to your eyes. It’s called “eye relief,” and you want 11mm or more.

            You can go far into the weeds on the lens materials and coatings, but know that newer “roof prism” models are lighter and smaller  than older “porro prism” models.

            Finally, buy from a company that offers a lifetime guarantee no matter what foolish thing you do to your binocs. I’ve utilized my lifetime guarantee four times now for reasons too embarrassing to divulge. Vortex, a Wisconsin company, offers this guarantee, and I’ve been very grateful.

 

Other Optics to Consider as Gifts

            Buy a folding glass hand lens for looking at plants and feathers, as well as the splinter in your finger. They come in different magnification powers, but a 10 power is plenty. I also like to buy one that comes with a LED light, which really helps seeing some flowers or mushrooms in a dark woods. 

            Buy a cheap one, as we have many times, and you get what you pay for. Spend at least $20 on one, and you’ll be much happier in the long run. They’re called “magnifying loupes” by most companies. Opticron and Bausch & Lomb make good ones, as do many other companies.

            On the other end of optical pleasures, consider going big and getting a spotting scope. If you live on a lake and enjoy watching birds and other wildlife out on the water, you will absolutely love having a scope. Again, Vortex makes scopes – Mary and I have an 11x33 zoom scope, which is compact and light for traveling compared to the much heavier 20x60 scopes. And ours came with that lifetime guarantee, too, which in this case, I’ve only had to use once. Dropping things gets easier as you age.

 

Celestial Events

            The peak Geminid meteor shower occurs in the predawn of 12/13. This can be a big one – 50 to 120 per hour, though the nearly full moon will be hard to block out.  An asteroid known as 3200 Phaethon is responsible for the Geminid meteor shower, but it’s still not known how material from the asteroid’s surface, or interior, is released into the meteoroid stream. 

            Our earliest sunsets of the year – 4:14 p.m. – already began on 12/5 and will continue at that time until 12/14, whereupon the sun will start setting later on 12/15. 

            12/14 also marks the date when in 1972, Eugene Cernan left the last human footprint on the moon (Apollo 17). Since the moon has virtually no atmosphere – and thus no erosion – his prints may last indefinitely. Hard to believe no human has set foot on the moon for 52 years!

            December’s full moon – the Cold/Long Night/Popping Trees Moon/Little Spirit – occurs on the 15^th. It’s the highest and northernmost of all moonrises in 2024.

            Most of the best planet watching in December occurs in the early evening. Look for Venus low in the SSW, Mars rising in the ENE after 6 p.m., Jupiter low in the ENE, and Saturn in the South. Mars will be just below the waning gibbous moon on 12/18. 

 

Thought for the Week

            “Plants and animals don’t fight the winter; they don’t pretend it’s not happening and attempt to carry on living the same lives that they lived in the summer. They prepare. They adapt. They perform extraordinary acts of metamorphosis to get them through. Winter is a time of withdrawing from the world, maximizing scant resources, carrying out acts of brutal efficiency and vanishing from sight; but that’s where the transformation occurs. Winter is not the death of the life cycle, but its crucible.” - Katherine May, Wintering: The Power of Rest and Retreat in Difficult Times

Sightings – Blue-spotted Salamander, Tufted Titmouse, Trumpeter Swans

            Scott Ruesch in Harshaw had two excellent sightings to report. First, a tufted titmouse appeared at one of his feeders on 10/20. Tufted titmice remain a southern Wisconsin breeding species, but are expected to eventually breed up here as climate change impacts continue. 

            And second, he spotted a blue-spotted salamander in early November hanging out on his driveway. This individual “should” have been well into hibernation had it read the books describing its normal behavior.

            Bob Von Holdt in Presque Isle has been following a family of trumpeter swans all summer and emailed and sent a photo on 11/12: “All 6 cygnets have survived as of today.”

            Mark Pittman on Lake Content (just below Big St. Germain Lake)  had more to report on trumpeter swans: “We have way more Trumpeter Swans than years past. Some days, upwards of 50. They seem to segregate in small family groups all around the lake. The thing I’m curious about is the fact that there are several mallards aggressively feeding very closely with most every group of swans. Sometimes 8 to10 mallards. Perhaps bits of deep water vegetation the swans pull up is a treat for the mallards?”

            A later email from Mark noted, “Our lake has an abundance of wild celery (aka eelgrass). The swans seem to be fond of that.”  

            Wild celery (Vallisneria americana) is indeed a choice aquatic plant that nearly all waterfowl absolutely love. And it provides shade, shelter and spawning habitat for a wide variety of fishes and invertebrates, so even more food is made available for those waterfowl who consume prey. 

            The plant looks nothing like the celery we grow in our gardens – it’s a submersed plant whose super-thin, ribbon-like leaves are nearly transparent, almost like cellophane. But it’s said to taste like celery. I haven’t tried it, so I can’t confirm this, but hence the name.

Why So Many Trumpeter Swans on Pipke Pond? – An Explanation

            In my last column, I mentioned the large concentration of trumpeter swans on Pipke Pond in Presque Isle, and I wondered why so many were gathering there. Eric Benn responded with a very thorough explanation, which I’ll very briefly summarize here. 

            In 2021, a water control structure on the south pond failed, resulting in the pond draining completely within a few weeks. The DNR issued an administrative order to the town describing how the repair work needed to be done according to statute and various legal rulings. 

            A committee to address the issue was eventually formed in later 2022 and began working with an engineering firm to design the repair. The committee then applied for a WDNR grant to pay for one-half of the project and received it this year, with the work to commence in 2025. 

            In the meantime, some work had been done to hold the water in the pond. The south pond had very little water in it until this spring, and it gradually filled nearly all the way up. The exposed soils and the low water led to a very healthy growth of vegetation along the shoreline and in the shallows. 

            Eric feels this aquatic vegetation has been the draw for the swans and other waterfowl, but suspects that when the structure is finally brought into compliance, that the consistent higher water will result in less forage, and thus fewer birds. 

            Time will tell, of course, but swans eat an enormous amount of vegetation, and this fall they appear to have been the beneficiaries of an unexpected but exceptional food base.

            

Wounded Deer

            On 11/3, Greg Bassett in Hazelhurst sent me this note along with a distressing photo of a deer with an arrow protruding from just below its eye and coming out the side of its neck: “John, this poor girl came to our yard earlier this week and continues to show about once a day. I thought if you can use the pictures in your article it might be a way to remind hunters to do a better job of placing their shots and following up after their shots to prevent this kind of misery for their targets. She is able to eat and the DNR rep who called me back said he had a case like this about a year ago and the deer has been spotted recently and seems to be doing okay – the arrow had come out and the wound has healed. Nevertheless, a clean kill is still the most  important part of hunting!! We are keeping our eyes on this doe, and I have a friend who can put her down if it looks like she is struggling.”

Wounded deer, photo by Greg Bassett

            Greg’s email led me to wonder how many deer during our archery and gun deer hunts are wounded and/or die later from wounding. I knew who to ask – Keith McCaffery. Why Keith? Keith began as a research biologist with the Forest Wildlife Research Group of the Wisconsin Conservation Department (later DNR) in 1963 and conducted deer and ruffed grouse habitat projects until his retirement in 2000. He served as the State Deer Biologist during that time, and continues to contribute to our understanding of deer biology and best management practices. It’s fair to say that no one knows more about Wisconsin’s deer than Keith.

            So, Keith sent me an article he’d written on the subject in 2019, and here’s my short summary:

            “Literature on firearm “crippling” is quite abundant and some of it dates to the 1940s.  Some of this information is based on hunter questionnaires and some is based on ground checks.  

“However, a couple of the best sources come from Wisconsin and are based on ground checks following deer hunts.  A series of surveys was conducted in central Wisconsin during the 1950s and 1960s . . . The pooled results of 11 such surveys indicated that the unretrieved wounding mortality averaged 6.7% as great as the counted harvest. Adding strength to these results was corroboration provided by the long-term (1963 to 1989) demonstration hunts at the Sandhill Wildlife Area, also in central Wisconsin . . . Again, the un-retrieved wounding mortality averaged 6.6% as great as the counted harvest.

            “The most intensive study of bowhunting to date occurred at Camp Ripley in the 1990s.  Here, detailed post-hunt exit-interviews and close examination of harvested deer found that 87% of the deer reported to have been hit were retrieved.  Only 13% went unaccounted for and many of these deer were believed to have survived.”  

            Other studies from many other states specifically on archery wounding-loss provide an array of loss percentages, but nearly all suggest a loss below 10%.

            Keith’s final thoughts on the matter are perhaps most important. “No wild creature dies peacefully between starched bed sheets. All death in the wild is violent by human standards whether it is caused by starvation, predation, or projectile. And, while we might bemoan what appears to be ‘waste’ when we lose a deer, we should remember that nothing really goes to waste in the woods. Something usually benefits from a dead deer. The beneficiary may be an admired scavenger like a bald eagle or a lesser noticed chickadee. Still, we have an obligation to hunt as humanely as possible.”

            My hope is for a good hunt with sharp-eyed hunters and accurate shots.

 

Winter Finch Forecast

            The Finch Research Network in Ontario recently put out its 26^th Annual Winter Finch Forecast, which analyzes cone crops across Canada to predict whether various species of finches will be able to remain in Canada because of good cone crops, or if they’ll need to migrate south to find food. 

            Food abundance is the key for winter bird survival, not winter temperature. When we want to find out inside information on someone, the mantra is always “follow the money.” For birds, the insider info comes from a different mantra – “follow the food.”

            So, here’s a quick summary of their predictions based on cone and fruit availability:

            Pine grosbeak: Most pine grosbeaks should remain in the boreal forest areas, but areas around Lake Superior and particularly northern Minnesota may see a larger movement as a weaker cone crop in northwestern Ontario is consumed.

            Purple finch: Purple finches have  already been moving south, as reported by Hawk Ridge at Duluth, Minnesota. The majority should leave Canada with a moderate flight that will go well south to the Great Plains and southern United States.

            Redpoll: First this news. In 2024, Common Redpoll, Hoary Redpoll and the Lesser Redpoll in Europe have all been lumped into the same species, now just called Redpoll. 

            As for their predicted presence this winter, redpolls focus on birch and alder seeds, as well as seeds from weedy fields, and the boreal forest appears to have average to above crops of both birch and alders. So, the finch forecast predicts little overall movement south, but hedge their bets by noting that fires and pests created some holes in the seed crop success, so we may see some southbound birds.

            Pine siskin: The forecast says, “Many Pine Siskins will remain in the boreal and western mountains this winter. [But] areas from Manitoba eastward affected by Spruce Budworm infestations have a poor cone crop.” So, some siskins may have no choice but to come our way, but it sounds minimal.

            White-winged Crossbills: The Finch Forecast says most white-winged crossbills should stay in the boreal forest due to good white spruce cone crops. However, on 11/9, Ryan Brady from Washburn posted this: “This morning I tallied a state record 1,322 White-winged Crossbills migrating along the south shore near Herbster, WI. In 4.5 hours, flock after flock chattered on their way, mostly in groups of 15-30 birds, sometimes high over the lake, and only occasionally dipping down to sample nearby spruces. This species was not expected to dip south much this winter but clearly they are vacating the eastern boreal forest and moving west in big numbers right now. Whether they stick around will depend on how much food they find here, but at least for now look for them primarily at spruces, hemlocks, and tamaracks in the northern half of the state.” 

            Evening grosbeak: The forecast says there should be a moderate flight of evening grosbeaks southward this fall. Evening grosbeaks are the most rapidly declining songbird in North America for reasons that are still unclear.

 

2024 Warmest Year on Record?

            Scientists with the European Union’s climate monitoring program say they are “virtually certain” that 2024 will become the warmest year on record. It will also probably be the first full calendar year when temperatures rose more than 1.5° C, or 2.7° F, above the preindustrial average – a critical line signaling that Earth is crossing into territory where some extreme climate effects may be irreversible.

 

Celestial Events

            The average ice-up date for 37-acre Foster Lake in Hazelhurst is 11/27, according to 48 years of data kept by Woody Hagge. Small, shallow lakes typically ice-up much earlier than large, deep lakes, so there’s a good two weeks of variability for this date depending on the lake.

            New moon on 12/1. Look after dusk on 12/4 for Venus two degrees above the waxing moon.

Sightings – Trumpeter Swans and a Great Egret

            On 10/30, Sarah Krembs told me she had received a phone call from someone who saw an unusual all-white bird flying around Pipke Pond in Presque Isle. It wasn’t a gull said the caller. What was it, she wanted to know?

            Sarah and I talked about the possibilities – after all, there aren’t that many all-white birds to choose from – but with so little information, we couldn’t draw any conclusions.

            The next morning, Sarah emailed this: “It’s an egret. I drove around Pipke Pond in the driving rain this morning. There are still a minimum of 16 Trumpeter Swans out there. But in addition to the swans this morning, along the shoreline, I spotted a blob of white between the swipes of my windshield wiper blades. I grabbed the binoculars, and I could see it was a cold, wet, hunched up Great Egret standing there. Poor guy. He should have flown south yesterday when the getting’ was good.”

            Great egrets are a rarity up here, but every few years one shows up. In a quick look at some of my old columns, I have records of one in our area in 2021, 2016, 2011, and 2009, so they do wander our way. But the sighting of a southern species like this always raises the question of what are they doing up here? 

            They are listed as a threatened species in Wisconsin, but while Wisconsin is at the northern edge of the great egret’s range, during the 2006 breeding bird survey in Wisconsin, 10 breeding sites were found in the state. Their primary range, though, is well south of here along the Mississippi River and around Horicon Marsh/Lake Winnebago. 

            Still, great egrets can turn up almost anywhere in the summer, often traveling hundreds of miles north from their spring rookeries, for reasons no one can say. But this late in the year? Well, it’s been a warm autumn overall, so perhaps this individual was just on an adventure and delaying its inevitable migration south.

            As for why 20+ trumpeter swans were hanging out on Pipke Pond, well, trumpeter swans don’t necessarily have to migrate south to survive, needing only open water and sufficient forage to stay north. For instance, a small flock stays all winter on the Manitowish River near Benson Lake. 

            However, most Wisconsin trumpeter swans migrate, and largely to Illinois, but they can go just about anywhere given that they’re a re-introduced native species hatched from Alaskan eggs, and thus don’t have an established migratory route in Wisconsin.

            Okay, well, why so many in one place? Territory defense only lasts until their cygnets hatch and leave the nest, or they may remain territorial until fledging of the cygnets, but after that, trumpeters obviously are happy to socialize. 

            And why so many specifically on Pipke Pond? Well, it must be good foraging, because trumpeters are North America’s largest waterfowl species, and they eat a lot. But many other Northwoods lakes have good forage, too, so . . . As with many things in nature, there’s no easy answer. “Knowledge is an island in a sea of mystery,” wrote Chet Raymo, and I abide by that.

            

The Muddy Ontonagon River

            I recently attended a wonderful event in Eagle River celebrating Joe and Mary Hovel’s selection for the 2024 Land Legacy Award from Gathering Waters, Wisconsin’s alliance organization for more than 40 Wisconsin land trusts. Joe and Mary have worked for decades to conserve and protect lands in the Border Lakes region of Wisconsin, as well as in Michigan’s Upper Peninsula and in Wisconsin’s Central Sands region. Together, they have raised public awareness of the importance of land conservation, served as watchdogs for land use, and negotiated and facilitated the purchase and sale of thousands of acres of land and conservation easements. 

            I have them properly placed on my “conservation heroes” pedestal where they belong. We should all aspire to work as hard for conservation as they do.

            During the event, Joe gave a talk on Wisconsin’s connection to Michigan’s wild and scenic rivers, and the question came up as to why the Ontonagon River begins clear but becomes quite red and muddy as it passes through wild sections of the U.P. Ron Eckstin, retired DNR wildlife manager, noted, “These [north shore] rivers flow through a wide band of red clay soils. The red clay soils are ”young” soils formed in glacial times on the bed of Lake Superior when the lake was much higher (Glacial Lakes Duluth and Algonquin). These soils are subject to natural erosion that is accelerated by agriculture, development and past lumbering. The “red” in the rivers is iron oxide formed when the red soils come in contact with oxygen.”

            I also brought up the impact of the intense logging and subsequent river drives that took place in the U.P. and Wisconsin, all of which scoured the river bottoms and obliterated shorelines. Can you imagine how much our narrow and shallow rivers were altered by literally tens of thousands of logs being driven down them, as well as the erosion of the river banks after the drives from the clearcutting to the river edges? 

            If you haven’t read Deep Woods Frontier: A History of Logging in Northern Michigan by Theodor Karamanski, I recommend it highly. The Diamond Match Company was the single biggest timber cutter in the UP, and their impact was immense. Kamanski writes,”The high water mark of pine logging in northern Michigan came in the 1894-95 season. Forest fires, caused by a dry summer but spurred by the debris from Diamond Match’s own logging, ravaged the woods of southern Ontonagon County. The fast burning fire did not consume the pine forests, but the trees were badly scorched by the blaze.” 

            Loggers were concerned that the wood had to be cut immediately or insects would consume it. So, they brought in “Six thousand lumberjacks, a small army, [who] labored the winter butchering the timber. Thirteen million board feet of pine per week fell in the wake of their cross-cut saws. A total of 1200 horses, brought from farms in far-off Iowa and southern Wisconsin, hauled the mountain of wood from the cuttings to the banks of the Ontonagon River . . . One hundred eight-five million feet of pine were scaled at the side of the Ontonagon River . . . it was estimated that if all the logs were loaded on railroad flatcars, it would take a train more than 250 miles long to carry the haul . . . 

            “It was at this point that the ambitious appetite of the Diamond Match Company ran afoul . . . of the serpentine Ontonagon River. Mammoth log jams occurred all along the course of the drive . . . For the remainder of 1895 and all through the spring and summer of 1896, the Ontonagon River remained choked at Grand Rapids . . . Finally in 1897, the jam was cleared and all the logs delivered to the lakeshore.” 

            Well, there’s so much more worthy of reading here, but the point is to try to envision 185 million feet of pine being cut in one year and sent down one river, and all the jams that ensued. The violent gouging of the river banks and the dredging of the river sediments is, for me, nearly impossible to imagine. At the time, this was considered the “world’s greatest logging operation.” What would have been its impacts to the red clay banks of the Ontonagon, and what are the impacts still today in this often hilly region of the U.P.? I believe it’s part of the reason the river runs so red.

 

The Flambeau Trail

            While I’m talking history, I read a recent article in “The Wisconsin Archeologist” (January-December 2023) by John Wackman entitled “The Montreal Portage Trail/Flambeau Trail – A History” that challenged what I thought I knew about the 45-mile long Flambeau Trail.

I had always understood there was a single trail starting at the mouth of the Montreal River that ran all the way to the north end of Long Lake in Iron County. From there, Native Americans and fur traders would paddle south to the base of Long Lake, enter Long Lake Creek, which flows into the Turtle River, then head into Echo Lake (formerly Big Turtle Lake) in Mercer. From there, a short 100-yard portage took them into Tank Lake (formerly Grand Portage Lake), then into a tiny creek that runs under Hwy. 51 right next to the giant fiberglass loon greeting folks entering Mercer, and into Mercer Lake (formerly Sugar Camp Lake). Then a nearly four mile portage had to be taken southeast through some serious wetlands into the Manitowish River. 

            Now the options were to head upriver on the Manitowish through the current “Chain of Lakes” in Manitowish Waters, which wasn’t a chain back then, and on into the Trout River to Trout Lake and through a series of lakes and portages to the Wisconsin River.

            Or they could go downriver on the Manitowish until they hit the Bear River, and paddle upstream into Lac du Flambeau. 

            Well, it turns out the Flambeau trail had two branches, one originating at the mouth of the Montreal, and the other at Saxon Harbor. Both, however, came together about three miles later near Saxon Falls. Which of the trails was the principal trail is a matter of conjecture, but Wackman believes the Montreal River mouth was the main starting point.

Montreal Portage Trail and Flambeau Trail

            The trail was first described in writing by Raddison in 1661 and Perrot in 1667, but was later described among others by Schoolcraft in 1820, Cram in 1840, Owen and Norwood in 1848, and Sweet as late as 1880. 

            The earliest use of the trail is unknown and can only be speculation. Archaeologist Robert Salzer (1969) described the long-term occupation on Strawberry Island in Lac du Flambeau: “We can hypothesize a minimum of three occupation periods: Middle Woodland (sometime during the first few centuries after Christ?); Late Woodland (beginning as early as AD 1000 . . .); and Historic, dating around AD 1900.” Without written records over these periods, the earliest use of the trail, which would have brought people to Strawberry Island, will likely never be known. 

            The trail was a 120-pause portage, a “pause” occurring when the travelers had to stop and rest, which depending on the terrain, was usually about a half-mile. 

            Think about this for a moment. What’s the longest portage you ever did? The longest single portage I ever accomplished was a one-miler in the Boundary Waters, and I was pretty spent after carrying a pack and a lighter weight canoe to the next lake. The voyageurs and natives carried 95 pound packs, but more often two packs, so they didn’t have to return and do the trail twice. 

            So, the Flambeau Trail was surely not for the faint of heart or frail of body. Francois Victor Malhiot, a 28-year-old Frenchman appointed to take charge of the North West Fur Company's trading post in Lac du Flambeau, crossed the Flambeau Trail in July of 1804. He's most often quoted for this observation of the trail: “Of all the spots and places I have been in my thirteen years of travels, this is the most horrid and most sterile. The Portage road is truly that to heaven because it is narrow, full of overturned trees, obstacles, thorns, and muskegs. Men who go over it loaded and who are obliged to carry baggage over it, certainly deserve to be called ‘men’ . . . This vile portage is inhabited solely by owls, because no other animal could find a living there, and the hoots of those solitary birds are enough to frighten an angel or intimidate a Caesar.”

            Attempts have been made to relocate the trail, but given the intensive logging that occurred in the late 1800s, and still occurs today, and how quickly trees grow back, the trail has for the most part been obliterated.

A Northwoods Almanac for 10/25 – 11/ 7/24

Avian Bird Flu

         Recent articles in the Milwaukee Journal Sentinel (“Bald eagle recovery a testament to wildlife protections, improvements,” Paul Smith, 8/4/2024) and The Washington Post (“In eagle nirvana, avian flu is decimating America’s national bird,” Mark Johnson, 10/5/2024) have raised concerns about the impacts of avian influenza on Wisconsin’s bald eagle population. 

         I read these avidly, because we had an active eagle nest across the river from us for decades, but we haven’t seen any nesting activity there or nearby for the last two years. So, we’re curious, too, regarding what may be going on.

         Eagles have been doing great in the seventeen years since the Fish and Wildlife Service removed them from the endangered species list, and numbers nationwide have continued to rise over that time. But avian influenza hit particularly hard in late 2021, and eagles began to die in many states. 

         In Michigan, the number of occupied eagle nests had risen from 52 in 1961, to 114 in 1984, and then to 1,000 or so by the end of 2021. Once avian influenza reached Michigan, the impact in 2022 was immediate – the number of occupied nests plunged 50 percent with tests on dead bald eagles performed by the Michigan DNR revealing that 38 percent of those that could be diagnosed had died of avian influenza.

         In Minnesota, eagles have been dying, too, but no comprehensive figures exist on the impact of the disease because the state does not collect all dead eagles for necropsy, the animal version of an autopsy.

          Eagles were dying even as far south in Florida and Georgia  where avian influenza caused an alarming rate of bald eagle deaths and nest failures. 

         How as this happening? Waterfowl were dying of “bird flu,” and the eagles were eating the waterfowl. 

         So, what’s been happening here? Wisconsin now has the third highest population of bald eagles in the nation, trailing Alaska and Minnesota, so this is a big concern. 

         The problem is it’s hard to say exactly, because the DNR no longer conducts aerial nest surveys, partly because the species is doing well and partly due to funding shortages that required its staff to focus on areas of greater need.

         To fill the void, Bald Eagle Nest Watch (BENW), a citizen science program begun in 2018 by the Southern Wisconsin Bird Alliance (then called Madison Audubon), started working in partnership with the WDNR. In 2022, as bird flu – more precisely Highly Pathogenic Avian Influenza (HPAI) –  spread through the wild bird population in Wisconsin, BENW documented a sharp reduction in nesting success.

         The disease was found in dead and dying adult bald eagles and was confirmed as a source of mortality in eagle chicks when BENW volunteers in Milwaukee County recovered a very young, recently dead eagle and submitted it for testing.

         The eaglet was positive for HPAI. It helped explain the 65% failure rate among Wisconsin eagle nests in 2022, according to BENW data. The program had documented an average of 19% nest failures from 2018 to 2021. 

         That was a very serious decline. However, the good news is that last year, 2023, bald eagles appear to have recovered well with only a 15% nest failure, at least according to the limited BENW data. 

         So far in 2024, BENW volunteers have monitored 219 active nests across 40 counties (out of 72 in the state) and found 43 nests (20%) failed, but for many reasons including being toppled during severe storms this spring.

         Drew Feldkirchner, Director Bureau of Natural Heritage Conservation for the WDNR, responding to a request for information from Ron Eckstein, retired eagle bander for the DNR in Rhinelander, wrote, “At this point, we have no plans to resume those [aerial] surveys. However, we are staying engaged on bald eagle work including the excellent NestWatch program led by Southern Wisconsin Bird Alliance. We continue to receive those data every year and take that information into account.”

         Carly Lapin, Northcentral Region Ecologist for the DNR, wrote, “As far as I am aware, we are not seeing the bald eagle die-off that we did several years ago at the peak of avian influenza in the state. In fact, our nest success numbers appear to have returned to normal, based on observations from NestWatch.”

         With eagles now nesting in all 72 counties, it may be that the eagles have dodged this current bullet, at least in this incarnation of HPAI. However, there will likely be more variants to come.

 

Sighting – Juncos and Harris’s Sparrow

         Dark-eyed juncos arrived at our feeders in Manitowish on 10/7 and a Harris’s sparrow visited our feeders on 10/10.

Harris’s sparrows are a far northern nesting sparrow that rarely visit on their spring and fall migrations, and one we haven’t seen for many years. It’s always a blessing when you look out your window and a rare bird looks back at you, isn’t it?

Lingering Trees

         Research into the natural genetic diversity and selective breeding of trees offers some  hope for imperiled tree species like ashes, American beech, eastern hemlock, butternut, American chestnut, and American elm. The trick is to find those very few trees that are surviving and showing resistance to these diseases, and then to crossbreed them in hopes of restoring them to some of their original abundance in our forests. 

         And that’s where all of us come in. Researchers need help finding “lingering” trees. If any of us are aware of a tree or trees that appear to be doing well – they’re “lingering” – while others of the same species around them are dying, we are asked to download the app TreeSnap and submit our observations. 

         A caution. It’s important to not submit observations of trees like eastern hemlock where the hemlock wooly adelgid (HWA) hasn’t reached as of yet, like our area in northern Wisconsin. But if you live in North Carolina or Massachusetts or other eastern states where the HWAs have killed millions of trees, then that’s the area where the survival of hemlocks is rare and needs to be documented.

         So, if you’re in an area that has been decimated by a specific tree disease or pest, but you see an individual or more doing well, consider sending information in to TreeSnap. Follow up questions will come your way, and your observations will not be shared with anyone except certified researchers in order to protect the trees. 

 

 Always More on Wolves 

         Pat Durkin in a recent excellent “Patrick Durkin Outdoors “column notes the following statistics (https://www.patrickdurkinoutdoors.com): “From 1985 through 2023 [38 years], the Wisconsin Department of Natural Resources paid $3.38 million in sundry veterinary bills and abatements [for wolf ‘depredations’] to cover 750 calves, 450 hunting dogs, 270 sheep, 235 chickens, 150 adult cattle, 150 domestic turkeys, 65 pet dogs, 25 horses or donkeys, and other livestock injured or killed by wolves.”

         Big numbers, right? Well, as Durkin points out, if you break them down in annual numbers over 38 years, those big numbers suddenly look pretty small, don’t they?

         More importantly to my mind, Durkin notes: “The DNR, however, doesn’t track or write abatement checks for cats, dogs, parakeets or other suburban pets picked off by foxes, coyotes, bobcats, raccoons, hawks or bald eagles. Good thing. Imagine the drama of politicians demanding the DNR hold those evil-doers accountable, too.”

         So true. Just wolves are the evil-doers. No coyote or bobcat or other predator gets headlines in papers for killing a lamb or calf or chickens or someone’s house cat. No one gets paid for losses from other predators. 

         And if you want to take it to its furthest end, no one gets paid for the damage woodpeckers do to all of our wooden siding. Or the damage sapsuckers do to our apple trees. Or . . . 

         Maybe the DNR should be paying us for all this other stuff, too!

         No . . . they absolutely should not.

         We live in a state that has exceptional wildlife. To enjoy the remarkable benefits of having them on the landscape, sometimes there’s a cost, one everyone should be more than willing to pay for the privilege of not living in a sterile city. 

         

The Other Side of the Wolf Coin

         Durkin also points out that there are those who think if we just had more wolves, we could eliminate CWD in deer. Or if we just had more wolves, they would control the ever burgeoning deer herd.         

         Nonsense. 

         I’ve written this before, but it bears continual repeating. All the best research has said that wolves eat from 17 to 20 deer annually. Multiply that times our 1,000 wolves, and that’s a pittance of 20,000 deer. If instead we have 1,500 wolves, as so loudly proclaimed by those who always believe they know better than the DNR, that’s a larger pittance of 30,000 deer. Out of a deer herd of somewhere around 1.6 million statewide – around 400,000 in the northern counties – that still leaves an army of deer on the landscape

         Simply put, wolves will never control the deer herd in Wisconsin. Never. 

         The math doesn’t work for the wolf haters, nor does it work for the wolf lovers.

         Now, if only math mattered. 

         Durkin ends his column with a perfect quote from wolf researcher David Mech who wrote in 2012, “The wolf is neither a saint nor sinner except to those who want to make it so.”

 

Celestial Events

            Planets to watch for in November: After dusk, look for brilliant Venus very low in the south-southwest; for Jupiter rising in the east-northeast; and Saturn high in the southeast.

            At dawn, look for Mars in the south-southwest.

            New moon on 11/1.

            The peak Taurid meteor shower occurs in the predawn on 11/5.

 

Thought for the Week

         The smoke from the first meaningful fire in the wood stove, the one that just might keep going now until spring, smells sweet and crisp from the white birch that has laid silent in the pile for two years, snapping now and crackling and popping, spinning tall tales in long shadows as the sun sets, luring us to the couch to warm our feet, the air inside now pungent, too, from opening the stove door for gentle rearrangements, encouraging fire from individual logs I recognize by now as old friends from all the cutting and the splitting and the stacking and the hauling, and with the possibility of the first flakes of the season flying by morning, we are exactly where we want to be, the inside of our house reflecting the magnificent yellow of our woods outside, and time is slowing in that perfect way that only happens when you light the first purposeful fire of the year. – Bob Kovar
