What’s Going on With The Trempealeau Eagles? Cooperative and Not-So-Cooperative Breeding in Bald Eagles

April 20, 2025: Mr. T's other nest and mate

Remember January and February of 2025? Bald Eagle Mr. T was attentive, his mate Mrs. T laid three eggs, and both eagles actively tended their nest. But after March 19, he began spending less time there. He disappeared entirely between March 27 and April 5, and when he returned, his visits were brief and infrequent. Mrs. T was left to manage the nest mostly on her own – although Mr. T brought in a few fish, he took more than

April 12, 2025: Mom flying to the nest

An update on Mom and DM2. Story and photos by Robin Brumm It’s been a really long time since I’ve gone to Decorah to check on Mom and DM2! Since the weather was finally cooperating for the weekend, I decided to go on Saturday morning, so I packed up my camera and off I went. To see Mom and DM2’s nest, you have to walk down the trail quite a ways. I always bring my foldable wagon and pack my

Two deaths, a new nest, and a mystery in Trempealeau

April 21, 2025: Mrs. T feeds TE3

It was a rough weekend and start to this week for the Trempealeau eaglets.  Yesterday, our camera operators documented Mr. T bringing fish to another nest. This morning, TE4 and TE5 died after Mrs. T left her nest to hunt in a cold, slashing rain. Bald Eagles usually take excellent care of their young and Mrs. T certainly did her best. What happened? 2024: First-Time Father? We’ve had a lot of questions about Mr. T’s behavior. In 2024, he gave all

Welcome to the World, TE5!

Welcome to the world, TE5!

Mrs. T has her talons full! TE5 hatched at 6:35 AM this morning! The T’s now have three hatchlings: TE3, who is turning six days old, TE4, who is turning four days old, and baby TE5. As of this post, TE3 and TE4 have each eaten nine times, with five feedings by Mr. T and four by Mrs. T. TE5 is still being nourished by the yolk it consumed shortly before hatching, but look for a feeding later today. Videos

Does Mrs. T Have A New Mr. T?

Mr. T in April of 2025. Thanks to GA Bear for the capture!

A combination of nest timing and behaviors made us consider the likelihood that Mrs. T could have a new Mr. for the second year in a row. Read on to learn more! Nesting records: A new mate (usually) equals later eggs In general, eagles tend to lay eggs later during their first season with a new mate and move laying earlier in the years that follow. Here’s what our records show: Egg-laying is influenced by individual, social, and environmental stressors,

Eaglet Growth and Development: Week One

March 27, 2024: An Eagletude fit for royalty! DN17 and DN18 turned three and two days old today.

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 one in this blog. What can we expect in the first week following hatch? Like humans, a growing eaglet has developmental

A leap of faith from N1

April 14, 2025: Goslings at N1

The goslings took their Leap of Faith from N1 this morning! The drop from the nest to the riverbank is about 70 feet. Five of the goslings made it: the sixth hit a branch below the Y and did not. The five that made it quickly re-joined their parents on the riverbank and are currently downstream from Siewers Spring Road. Make way for goslings, everyone! Hatch watch for N2B begins on Friday, April 18. Link: https://www.raptorresource.org/birdcams/decorah-goose-cam/

April 13, 2025: The goslings a few hours after hatch

Make way for goslings! The goslings in N1 are hatching and we’re getting a lot of questions about the gosling Leap of Faith, which will probably happen tomorrow or Tuesday. Will the goslings jump? How will they survive? Are they really ready to leave the nest? Read on for the answers to your questions and watch live here: https://www.raptorresource.org/birdcams/decorah-goose-cam/. Will the goslings really jump? They will!  Watch for The Leap of Faith to happen roughly 24 to 48 hours after

Cuteness overload and hip hip hooray! TE3 got a nice feeding this morning and it looks like TE4 is on its way! Cuteness overload and hip hip hooray! TE3 got a nice feeding this morning and it looks like TE4 is on its way! Note the delectable little bites!
