A Northwoods Almanac for 3/27 - 4/9/2026
Sightings - Sharp-shinned Hawk, Purple Finch, Tree Sparrow, Dark-eyed Junco
Our blizzard on 3/15 and 3/16 brought four new species to our feeders - a sharp-shinned hawk, several purple finches, a dark-eyed junco, and a tree sparrow. Hunger is certainly a motivator!
The sharp-shinned sat on a branch near one of our feeders and would have been easily seen by any nearby bird. I wondered at its tactics, but perhaps it thought that the weather would force a young bird to take a chance on getting a seed and not know what hit it.
I turned my head briefly to talk with Mary, and the branch was empty when I glanced back. Whether the sharpie grabbed a songbird or not, I don’t know, but we’ve not seen it since.
Migration is on! The birds that wintered-over not far south of here are the first to return, so you will likely already be seeing American robins and red-winged blackbirds, common grackles, and European starlings by the time you read this. Whether we will get a flight of redpolls and pine siskins yet this early spring is an open question - they’ve been a scarce commodity all winter for most of us.
Manitowish River Opens
The Manitowish River opened up below our house in Manitowish on 3/9, which is a bit early - the average date is around 3/16.
In 2024, the river only iced-over for two weeks - from Jan. 15 to Jan. 30, the shortest period in the 42 years we’ve been here.
The latest year of opening was 2014 when the ice went off on 4/10.
As soon as the ice is was off, we heard Canada geese honking on the river.
Trumpeter swans are back, too, though since some winter-over on the Manitowish, it’s hard to know who is a recent migrant and who has been here all along.
We saw our first hooded mergansers on the river on 3/17, and I suspect common goldeneyes were here by then, too, but it’s always a bit of luck to see any bird at a specific time and place.
The early waterfowl migrants are those who wintered only as far south as open water. Later waterfowl migrants, like blue-winged teal, winter in Central and South America, so their appearance is delayed. But most of “our” waterfowl winter in the southern U.S., so they show up quickly after ice-off.

Papa Hambone
There have been many superb Wisconsin writers on the natural world - Aldo Leopold sitting on top of the pedestal - but I suspect there has never quite been one like George Vukelich. I was speaking earlier this month at Canoecopia in Madison on the topic of “The Love Language of Rivers,” a fancy title for me sharing excerpts from writers who have written beautifully of their love for rivers, and one of the excerpts I chose was from George Vukelich.
After my talk was over, a gentleman introduced himself to me as Vince Vukelich, one of George’s children. He wanted me to know that many of George’s articles and recordings are on this website: www.papahambone.com.
George wrote two columns weekly for the Isthmus of Madison, a monthly column for the Wisconsin Outdoor Journal, columns for the Capital Times and Madison Magazine, produced a dozen documentaries, and hosted the WPR program Pages from a North County Notebook on Sunday nights. His two books, North Country Notebook Volume 1 and North Country Notebook Volume 2 are always in reach on my overcrowded bookshelves. And he also wrote a novel, Fisherman’s Beach.
Back in 1993, I wrote a review for the Wisconsin Academy Review (now Wisconsin People and Ideas magazine) of his North Country Notebook Vol. 2. In it I said: “Vukelich's writing bridges the abyss that usually separates the stereotypical consumers (hunters/fishermen) and the non-consumers (hikers, birders). He's anthropomorphic without falling into handkerchief sentimentality, and without giving up his license to catch (‘prune back’ says Vukelich) innumerable fish. There's wisdom and perspective here, characters we can relate to, all given with a strong dose of laughter. He says, ‘When you live up in the North Country in winter, you just naturally keep track of things because you could wind up freezing your buns if you don't.’”

Impacts of a Blizzard and All Weather is Local
I imagine the species of wildlife that was happiest about our blizzard was snowshoe hare. Deep snow acts as a trap for most predators while serving as a distinct home-field advantage for a snowshoe hare who can stay on top of the snow with its enormous feet.
For most species, however, travel became very difficult and food resources were blanketed with snow. March is known as “the starvation month,” so the particular timing of this storm could have spelled trouble - many species are likely barely holding on in anticipation of spring finally arriving.
On the other hand: It’s been the warmest March on record so far across the United States in terms of daytime high temperatures. Not only will temperatures break March monthly records out West in particular, but this heat wave will apparently even break April records. Around 800 high temperature records were forecast to be neared, tied or broken at 165 locations in Western and Central states - some by more than 10 degrees - with unusual warmth set to linger into late March.
Good News for the Eastern Monarch Butterfly Population
The eastern monarch butterfly population overwintering in Mexico’s oyamel fir forests occupied 2.93 hectares (7.24 acres) during the 2025-2026 overwintering season, according to the latest survey released by the World Wildlife Fund (WWF) and Mexico’s National Commission of Protected Natural Areas (CONANP). This represents about a 64% increase compared to last year’s estimate of 1.79 hectares.
Each winter, researchers survey monarchs while they cluster together at their overwintering sites in central Mexico. Rather than counting individual butterflies, scientists estimate population size by measuring the total area of trees occupied by monarch clusters. One hectare equals approximately 2.47 acres, or just over two American football fields. Although the number of monarchs per hectare varies by year and site, estimates suggest roughly 20 to 30 million monarchs per hectare, with a median estimate of 21.1 million.
So, with nearly 3 hectares of habitat, their population should be around 60 million.
However, the eastern monarch population remains below levels considered necessary for long-term sustainability. Research suggests that at least 6 hectares of occupied overwintering habitat are needed to support a stable eastern migratory population.
Year-to-year changes in population size depend on conditions across the entire migratory range, including the availability of milkweed and nectar plants during the breeding season, weather conditions along the migration route, and habitat quality at overwintering sites.
Conditions during the 2025 breeding season were more favorable for monarchs than in 2024, hence the higher numbers. The year 2024 got hotter and drier in the Upper-Midwestern monarch breeding range as the summer progressed leading to lower-than-expected numbers of monarchs in the second and third generations of 2024. When the late summer monarchs left their northern breeding grounds in 2024, they also faced large areas of drier-than-normal conditions through the U.S. part of their migration.
The summer weather in 2025 was closer to normal, so they fared better.
The best way to support monarchs is to create more habitat for them (milkweed species!), and to keep those habitats free from harmful insecticides.

SNAs Anniversary
This year marks the 75th anniversary of the Wisconsin State Natural Areas Program, the oldest and largest of its kind in the country.
The Wisconsin Legislature created the State Natural Areas Program in November 1951 to protect the best examples of Wisconsin's native natural communities.
The DNR, in collaboration with over 60 partners, cares for nearly 700 sites that protect outstanding examples of Wisconsin's native landscape of natural communities, significant geological formations and archeological sites.
More than 230 animal and plant species are listed as endangered or threatened in Wisconsin. Over 90% of those listed plant species and 75% of the listed wildlife species are found within state natural areas.
Nearly all state natural areas are open to the public for hiking, hunting, bird-watching, nature study and photography, but most are largely undeveloped.
Vilas County leads the state with 33 SNAs, followed by Door County with 29, and Bayfield County with 28.
Celestial Events
April’s full moon occurs on the 1st, and is aptly referred to by various tribal nations as the Awakening Moon, Grass Appearing, or Maple Sugar Moon.
We’re up to 13 hours of sunlight as of 4/5.
For April planet watching, look after dusk for Venus low in the northwest and Jupiter in the west. Before dawn, Mercury can be seen very low in the East, Mars also very low in the southeast, and Saturn rising in the east.
Thought for the Week
“I would rather be ashes than dust. I would rather that my spark should burn out in a brilliant blaze than it should be stifled by dry-rot. I would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet. The proper function of man is to live, not to exist. I shall not waste my days in trying to prolong them. I shall use my time.” - Jack London
