About the Trempealeau Eagles

About the Eagles

The Trempealeau eagles are nesting on private property in the city of Trempealeau, Wisconsin. Their nest is located in a white pine tree overlooking the Mississippi River. In general, the eagles begin courtship in October, productive mating in late January or early February, and egg-laying in mid to late February. Hatching usually begins in late March to early April, and the eaglets fledge in mid-to-late June. While young usually disperse between August and October, the adults remain on territory year round.

The eagles eat live and dead fish, squirrels, other birds, rabbit, muskrat, deer, possum and anything else they can catch or find. To learn more about bald eagles in general, please follow this link to the Cornell Lab of Ornithology website.

Adults

For now, we’re referring to the eagles as Mr. and Mrs. T. If that changes, we’ll let everyone know!  

Nests

March 20, 2023: HM and her eggs

When will our eagles lay eggs?

When will the Decorah and Decorah North eagles begin laying eggs? While nest timing can very from region to region (Florida, for example, is quite different from Iowa), mark your calendars as follows! Eagles in Florida are beginning to lay eggs. Does Mr. and Mrs. T’s recent copulation mean that we’ll soon see eggs there as well? It does not! Bald eagles have been documented copulating ten months of the year, but in the Upper Midwest and Colorado, they don’t

Birds and Nest-Building

When I say ‘bird’s nest’, you know the type of nest I’m talking about, right? It could be a bald eagle’s stick platform high up in the branches of a tree. Or perhaps a peregrine falcon’s scrape in dirt, sand, or gravel on a shallow cliff ledge. Or maybe the burrows that bank swallows and belted kingfishers excavate in dirt, the cavity nests that woodpeckers excavate in dead wood, or the woven nests that orioles and weavers build. When I

Happy Halloween 2024

Happy Halloween! Have a boo-tiful day and a bewitching night! Trick or treat? Birds do both!

The ways in which we watch and learn about birds – HD cameras, high-powered spotting scopes and lenses, satellite transmitters, and DNA analyzers – are new, but our interest in birds is very old. Sacred and magical birds are common in folklore, oral traditions, and religious texts, including the Bible, the Torah, the Qur’an, and the Bhagavad-gita. It’s easy to say that ancient people lacked a global perspective and scientific knowledge, but a quick search for birds + omens shows

Eaglet Growth and Development: Week Four

We’re writing a series of blogs about the first few weeks of an eaglet’s life. An eaglet spends roughly 75 to 80 days in the nest. For about the first half, it grows and gains weight. For about the second half, it grows flight feathers and starts developing the skills it will need post-fledge. We will focus on week four in this blog. During week three (fourteen to twenty-one days), the dynamic duo shed most of their natal down, gained

Bald Eagles, Menopause, and Ova

Do bald eagles go through menopause? Probably not, since we’ve documented menopause or prolonged post-reproductive lifespans in just four species.

November 13, 2024: Meet me at the Love Branch!

♪ The Love Branch ♫ is a little ole place ♫ where ♩ Bald Eagles get to-getherrrrr ♫ In this case, the Love Branch is a well-worn white pine branch and the eagles are Mrs. T and Mr. T, on (we think) their second year as an eagle couple. Bald Eagles have been documented copulating ten months out of the year; at our latitude, they copulate productively between mid-January and early March, but they also copulate outside that time frame

October 28, 2024: Tricks and Treats from the North Nest, the Flyway, and Trempealeau!

Happy Halloween week! Today’s treats include a meteor shower, a splish-splash eagle bath, and a fox squirrel stealing a pileated woodpecker’s snacks…the naughty trickster! This week, we’re looking forward to nestorations, Flyway and North Nest arrivals and departures, especially on Wednesday when the warm southerly wind finally changes direction, and more sightings of our North Nest neighbors. The warm extended fall makes it feel like summer, but the north nest neighbors are clearly preparing for winter and – in the

October 21: It’s stick time! News and NestFlix from Decorah North and Trempealeau

It looks like eagles at all of our nests have started nestorations! DNF, Mr. North, and Mr. and Mrs. T are visiting Nest Depot, flying in sticks, inspecting one another’s work, and tangoing away to put everything in the perfect place. While HM and HD don’t appear inclined to come back to N1 or to adopt N2B, we have seen them fishing the pond and carrying sticks to the east. We’ll go scouting for their latest nest and for Mom

October 16, 2024: Trempealeau Eagles, Decorah North, and the Flyway!

It was a busy day for eagles – and other birds! – today. At Trempealeau, Mr. and Mrs. T attended to some sticky business as they figured out furniture placement, tangoed, and made early home improvements. We believe that it’s Mr. T’s second year as a mate and father, so we’re very curious to see how he’ll do with food gifts to Mrs. T, brooding, and feeding his young.
