A Northwoods Almanac 12/21/18

A Northwoods Almanac for 12/21/18 – 1/3/19  

Manitowish Waters Christmas Bird Count
            On 12/15, eleven intrepid birders fanned out in the Manitowish Waters area to count birds as part of the Audubon Christmas Bird Count. The morning began sunny and cold at 12°, but warmed to 40° by 11 a.m. It may have been the most comfortable Christmas bird count of any of the 25 we’ve done prior to this! 
            It may also have been the quietest.
            Every participant commented on how few birds they’d seen or heard that morning. Our total number of individual birds were well below our average. Still, we somehow came up with 28 species, which is above our average of 25! 
            Quite unusual were sightings of a wood duck, a hooded merganser, and a red-breasted merganser – waterfowl are typically long gone by the time we do our count. 
Conspicuous by their absence were birds like gray jay, bohemian waxwing, purple finch, both crossbills, and all raptors other than eagles. More unusual yet were the very low numbers of common winter visitors like pine siskins, common redpolls, pine grosbeaks, and American goldfinches.
            Their relative paucity leads me to wonder about our conifer cone crop. I see very few cones on white pines, eastern hemlocks, balsam firs, and both spruces, so perhaps our dinner table is a bit bare for them. Time will tell, of course. They may simply be biding their time until they’ve run out of food further north and are forced to forage come south and visit our feeders. 

Sightings: Weasel, Pileated Woodpecker, Basswood Seeds 
            Bob Collins dropped off a photo of a weasel chasing a gray squirrel around a tree on his property in Hazelhurst. While ermine are exceptionally quick and ferocious hunters, I wonder about their ability to catch a squirrel up in the trees. Squirrels are circus acrobats, the flying Wallendas of the rodent world, racing around in the branches, performing amazing leaps between trees, and leaping from trees to the ground. Can a weasel match their agility? I don’t know, but every article describing their diet includes squirrels, so perhaps they can win an arboreal chase. Their normal bill-of-fare, however, is more grounded and includes chipmunks, ground squirrels, insects, small birds, frogs and snakes.

            Bev Engstrom sent several superb photos of a pileated woodpecker in flight amply illustrating their marvelous size. Pileateds are the largest commonly seen woodpecker in North America and the sixth largest in the world. Roughly crow-sized, they’re 16 to 19 inches long, with a wing-span of 26 to 30 inches, and an average weight of 11 ounces.

Pileateds play a crucial role in forest ecosystems by excavating large nesting and foraging cavities that are subsequently used by a diverse array of birds and mammals, particularly secondary cavity users. These are the cavity nesters who are unable to excavate their own cavities, but utilize natural cavities or those already created by primary excavators like pileated, flickers, red-headed woodpeckers, and yellow-bellied sapsuckers. Secondary cavity users include bird species like wood duck, bufflehead, common merganser, common goldeneye, American kestrel, screech owl, saw-whet owl, tree swallow, red-breasted and white-breasted nuthatch, black-capped chickadee, and mammals like American marten. 
Pileateds also are important in helping control some forest beetle populations because their diet consists primarily of wood-dwelling ants like carpenter ants and beetle larvae.
I’m told some folks still shoot them, thinking they’re harming a tree. Far from it, they’re performing surgery! They’re good guys, deserving of our admiration and protection.
Lastly, the seed-du-jour visible everywhere on ski trails this winter has been basswood. The pea-sized seeds hang on a stem from a narrow parachute-like structure – I think they look like little hang gliders. Basswoods, like all trees, are cyclical in their production of seeds, and 2018 looks like the year they chose to be celebratory.



Celestial Events – Days Now Growing Longer
Today, 12/21, marks the winter solstice. The sun is now its furthest south of the equator, providing us with only 8 hours and 39 minutes of day length. Or if you prefer, tonight we’ll have 15 hours and 21 minutes of dark. To mark the sun’s passage back north, try fixing a bit of tape to your window on which you’ve written the date. 
The full moon – the Cold/Long Night/Popping Trees Moon – occurs on 12/22. This is the year’s northernmost full moon rise and the year’s highest altitude in the sky for a full moon.
            The 22ndis also the peak Ursid meteor shower, a modest affair offering an average of 10 meteors per hour. Look predawn for the best show, though the light from the full moon will likely wash out most viewing. 
Christmas day, 12/25, gives the gift of our first day growing longer since June 20 – hooray!
12/27 to 1/7 mark the year’s latest sunrises. Every morning look at 7:40 for the first rays of the sun. These sunrises are 3 hours and 32 minutes later than our earliest sunrises which occur in mid-June at 4:08 (5:08 Daylight Savings Time).
As of 12/30, our days begin growing longer by 1 minute/day – we’re starting to cook now!
            On New Years’ Day, 1/1, we’ll be up to 8 hours and 45 minutes of daylight, or 36% daylight! Look before dawn for Venus just 1.3° south of the waning crescent Moon.
            On 1/2, the Earth will be at perihelion, its closest orbital point to the Sun in 2019, a mere 91.4 million miles away. This proves that the distance between the sun and the earth has very little to do with the warmth on any given day. It’s all about the tilt of the Earth, not the distance to the sun. At perihelion, we’re 3.1 million miles (3.4%) closer than during aphelion, our furthest away point, which will occur this year on July 4.
Look for the peak Quadrantid meteor shower on 1/3. At 40 meteors per hour, this might be worth braving the cold for. Look also before dawn for Jupiter about 3° south of the waning sliver of moon.

Future DEET Alternative?
Yes, it’s winter and mosquito larvae are all under water, but it’s never a bad time to talk about natural controls. So, I’ve just learned that compounds derived from coconut oil have been found to repel some insects better than DEET, at least according to a U.S. Department of Agriculture bulletin published in September in the journal Scientific Reports. The study found that fatty acids derived from coconut oil had long-lasting insect-repelling properties against flies, ticks, bed bugs and mosquitoes. Note that the compounds extracted from coconut oil – notthe oil itself – were found as an effective repellent (so, don’t go slathering yourself with coconut oil this spring).
The USDA release says the coconut oil compounds out-performed DEET at repelling stable flies, and repelled bed bugs and ticks for two weeks, as compared with DEET's three days of effectiveness. However, the study notes that a much greater concentration of coconut oil acids are required to effectively repel mosquitoes as compared with DEET. Ah, well.

Solutions Needed!
            Most social media feeds are filled with people complaining about various political problems without even attempting to discuss, or offer, solutions. I’m often guilty of that when discussing climate change, even though I know the key to fixing problems is offeringnew approaches and ideas, or examples of proven solutions. So, what can be done to alter the accelerating trajectory of climate change? Here are ten of the best ideas I’ve found, and all can be done without significant sacrifice:
·      Expand renewable energies dramatically and slash our use ofcoal and oil as far as we can. 
·      Maximize vehicle fuel efficiency and the heating and cooling efficiency of all buildings.
·      Place limits on the amounts of carbon that industries are allowed to emit. 
·      Invest heavily in existing/developing efficient energy technologies and industries.
·      Plant trees and dramatically reduce tropical deforestation. 
·      Eat lower on the food chain and purchase all goods from sustainable sources - know what and from whom we’re buying.
·      Reduce our consumption and waste of virtually everything.
·      Educate all girls everywhere and reduce the world’s population through family planning.
·     Read. Become well-versed in the issues. Trust the sciences. 
·      Support national and international climate change policies. Work for immediate change.
Kathleen Dean Moore writes: “People ask me, What can one person do? My answer is always: stop being one person. Join up with other people, brainstorm together—what are our skillsets, what are our challenges? Climate change can be such a lonely sorrow. No one talks about it, and you think no one is worried about it, but when you find your group, you’re really empowered . . . This is going to have to be systematic change and that takes community organizing and public action.”
Mary Oliver writes, “The world, moist and beautiful, calls to each of us to make a new and serious response. That’s the big question, the one the world throws at you every morning. ‘Here you are, alive. Would you like to make a comment?’” 
Far be it from me to ever offer any change to a Mary Oliver quote, but I’d substitute “commitment” for “comment.” And climate change is where we need commitments.

A Northwoods Almanac for 12/7/18

A Northwoods Almanac for 12/7-20, 2018 

Sightings: Northern Shrike, Barred Owl, Spruce Grouse, Red-bellied Woodpecker
We had our first northern shrike of the year visit our feeders on 11/27. Mary and I watched it for five minutes as it fluttered slowly up and down from tree to tree, an unusual behavior for a lightning-fast bird that predates on smaller songbirds. We speculated that it was trying to flush songbirds from dense vegetation where they might have been concealed. It was unsuccessful in the time we watched, and we haven’t seen it since. Ryan Brady photographed a northern shrike capturing a white-breasted nuthatch at one of his backyard feeders in Washburn – see the photo.

Mark Pflieger recently hung a deer carcass in his yard near McNaughton, and that evening a barred owl came in and dined on it for two and a half hours. Mark noted that it “looked like it was starving,” which is a likely scenario given that barred owls are not known to feed on carrion. Barreds are a true generalist predator, consuming a variety of birds up to the size of grouse and small mammals up to the size of rabbits, while during the summer, amphibians, reptiles, and invertebrates are also taken. In the winter, however, they feed mostly on small mammals like rodents and squirrels.

John Heusinkveld reported seeing four spruce grouse on private land in the town of Newbold, which may be the most southern record in Wisconsin for a sighting of spruce grouse. He noted “at one point, we walked directly underneath them at maybe 12 feet. This was the best photo, but we also got video of the male eating buds off a jackpine . . . I’ve stomped the Northwoods for 17 years always wanting to see just one. He was fat, proud, magnificent and unconcerned. They all were. The two apparent juveniles seemed to be males by plumage, but inconclusive. We watched them for 15 minutes with 10x40 binocs. So, it was my Christmas ‘And a Spruce Grouse in a Jack Pine,’ to the tune of ‘A Partridge in a Pear Tree.’ It felt like hope in this crazy age.”


Chuck Dutton on the north end of Squaw lake in Lac du Flambeau reported having had a pair of red-bellied woodpeckers feeding in his yard since October. 

Christmas Bird Counts
The 26thannual Manitowish Waters Christmas Bird Count (CBC) takes place on Saturday, 12/15, and less than a week later, the Minocqua CBC, sponsored by the North Lakeland Discovery Center Bird Club, takes place on Thursday, 12/20.  
For the Manitowish Waters Count, if you live within a 7.5 mile radius of the intersection of Hwy 51 and Cty. W, you can count birds in your own yard and from your bird feeders, and then report the results. For the Minocqua Count, if you live within a 7.5 mile radius of the intersection of Hwy 51 and Hwy 70 West, you can likewise count birds in your own yard and report the results. If you have friends or family who live within these areas, please also encourage them to count birds in their yard and report their results to us.  
If you’d rather not count but would be willing to have us come to your yard some time during the day to count your birds, let us know. We’ve learned a long time ago that winter birds know where the best restaurants are, and that’s folks’ backyard feeders.
The  CBC is a census of birds in the Western Hemisphere, performed annually by volunteer birdwatchers and administered by the National Audubon Society. This will be the 119thyear of Christmas bird counts, making it the longest running citizen science survey in the world.
The data helps to provide an understanding of bird population trends across North America in early winter, and provides an enjoyable social experience – tens of thousands of birdwatchers participate in this event each year.
More than 100 Christmas bird counts take place in Wisconsin. If you’re interested in participating either as a field counter or by counting birds at your feeder, please contact Donna Roche (p-lanz@hotmail.com) for the Minocqua count or contact me (manitowish@centurytel.net)for the Manitowish Waters count. 

Snowy Owl Status
As of November 26, Ryan Brady, Bird monitoring coordinator for the WI Bird Conservation Initiative,noted that “an estimated 26 snowy owls have been reported from 14 Wisconsin counties. 
“The total of 26 owls is well short of the 97 seen by this date during last year’s big irruption but greater than the 7 seen by now in 2016-17, which was a non-irruption year. While it’s a little early to know exactly how things will unfold by mid-winter, one thing is already clear – the proportion of juvenile birds hatched last summer is much lower this year than recent years past. This is consistent with reports from the Arctic that suggested a summer of low lemming numbers and poor reproductive success for snowy owls.”

Monarch Butterfly Status
            I tried this week to find the latest information on the status of monarch butterflies, but I was only able to find information up through the fall migration. Still, it was very encouraging. Based on activity in the monarchs’ primary Midwestern breeding grounds, Monarch Watch founder and expert Chip Taylor predicted in September that “the migration should be the strongest since 2008.” He wrote that “the sequence of events and temperatures that determine how the monarch population grows through the season has been better this year than for any year since 2001 . . . but there is still a big unknown. Will the fall conditions favor survival during the migration? Most of the migration through Texas occurs in October so should sufficient rains occur, nectar scarcity would not be an issue. Monarchs then still have to pass through northern Mexico, a traverse of another 600 miles or more depending on the routes taken.” 
Apparently, mortality during migration may have increased in recent years for monarchs, potentially contributing to the declines in their overwintering population. For example, the abundance of monarchs was one of the highest in decades in the Northeast during the 2017 breeding season, but in the subsequent winter, the population was well below historic levels in Mexico, likely linked to the fact the southern autumn of 2017 was the hottest in over 100 years. 
            So, even though 2018 was a great year for monarch reproductive success, the jury is still out on their migratory success.

Fourth National Climate Assessment
Volume II of the Fourth National Climate Assessment was released on 11/23 by the United States Global Change Research Program.President George H.W. Bush signed the Global Change Research Act into law on November 16, 1990, with a mandate to understand and respond to global change, including the cumulative effects of human activities and natural processes on the environment.
The National Oceanic and Atmospheric Agency (NOAA), one of thirteen federal agencies comprising the USGCRP team, was the administrative lead agency. The report was produced with the assistance of 1,000 people, including 300 leading scientists, roughly half from outside the government. For the 1,500-page report, go tohttps://nca2018.globalchange.gov

Copper Bullets
Several readers noted that they had switched from lead bullets to copper bullets based on what I had written in my last column. Randy and Debbie Augustinak in Land O’ Lakes noted that “initial attempts to locate all-copper bullets locally were futile (i.e. Fleet Farm & others), but we were eventually able to order them online from Cabelas. We subsequently learned that the national chains carry these products because non-lead shot is mandated in California.”
I’m very surprised to learn that copper bullets aren’t available locally – if true, consider contacting your local supplier and requesting they stock copper ammo.

Winter Solstice
Cold temperatures are only one element in the difficulty of living out a northern winter – the long nights are the other. For many of us, the coming of the winter solstice is truly a time for celebration given that in the Northern Hemisphere, the December solstice marks the turning point for the return of light. 
The 2018 December solstice takes place on Friday, December 21 at 4:23 p.m. CST, marking our shortest day – 8 hours and 39 minutes. 
But, in fact, our earliest sunsets occur at 4:14 p.m. from 12/5 to 12/14.So, why doesn’t the earliest sunset come on the shortest day? Here’s the answer from earthsky.org: 
“The key to understanding the earliest sunset is not to focus on the time of sunset or sunrise. The key is to focus on what is called true solar noon – the time of day that the sun reaches its highest point, in its journey across your sky. In early December, true solar noon comes nearly 10 minutes earlier by the clock than it does at the solstice. With true noon coming later on the solstice, so will the sunrise and sunset times.
“It’s this discrepancy between clock time and sun time that causes the Northern Hemisphere’s earliest sunset and the Southern Hemisphere’s earliest sunrise to precede the December solstice.” Got that?

Celestial Events
            The new moon occurs tonight, 12/7. 
The peak Geminid meteor shower takes place on the night of 12/13 through the predawn of 12/14. This is the year’s best meteor shower, averaging 50 to 100 meteors per hour.
