Trempealeau Eagles and Blogs

April 15, 2024: NestFlix and News From Decorah North, the Trempealeau eagles, and N1

April 15, 2024: Natal down mohawks, thermal down bodies.

Time to Nestflix and chill! At Decorah North, our grey grey tweagles are eating fish tails, sprouting pinfeathers and mohawks, coughing up pellets, and making all of their milestones! At Trempealeau, Mrs. T brings in an impressively large suckerfish and she and Mr. T defend the nest from a barred owl. The geese jumped this morning. Five of the six survived and the little family paddled downstream this morning. Perhaps we’ll see them below N2B or at the hatchery pond!

April 8, 2024: What are we looking forward to this week? News and NestFlix from around our Nests!

April 6, 2024: Look at those clown clompers! The eaglets' feet and legs have turned orange and are growing rapidly. It won't be long before they can stand on their feet.

What a weekend! The second eaglet hatched at Trempealeau, a male eagle – Mr. T? – has finally started to help with brooding and stocking the pantree, and the tiny North nest bobbleheads were replaced by great growing eaglets in grey flannel pajamas. We’re looking forward to hatch at Xcel Energy’s Fort St. Vrain nest on or around April 10, hatch at the N1 goose nest next weekend, and the leap of faith a day or two later. It’s springtime

Trempealeau Eagles Update

April 4, 2024: Feeding T1 at Trempealeau

What’s going on at the Trempealeau eagle nest and where is Mr. T? We haven’t seen him since March 28. Prior to that, he and Mrs. T were exchanging incubation duties and he was acting like a normal eagle Dad. But we haven’t seen him on the nest since his last shift and no one has reported or found him, live or dead, in the vicinity of the nest. The couple’s first eaglet hatched on very late on April 2nd

Bald eagle tongues and beaks!

March 25, 2024: DN17 and 18 eat.

We know that bird beaks are specialized for feeding and daily tasks. Birds of prey have strong, curved beaks with sharp edges to help them tear meat. Falcons specialize even further, adding a tomial tooth to help them kill prey. Dabbling ducks have tiny, comb-like structures on their beaks to strain small animals, insects, and plants from water and mud, while piscivorous ducks have saw-like structures to help them hold on to struggling fish. But what about bird tongues or,

March 13, 2024: News and NestFlix from Decorah North, Trempealeau, and the Geese!

March 13, 2024: I want to reach in and remove this! Mr. North and DNF are undergoing some body molt right now, and the feathers end up EVERYWHERE!

Happy Hump Day, everyone! Before we get into the NestFlix, a quick calendar round-up: Thanks so much for all you do: for watching, sharing, learning, and especially for caring! Among many other things, we’re busy trying to document nesting peregrine falcons right now, so if you get a band number, give me an email: [email protected] Decorah North Nest March 12, 2024: Days end beauty – https://youtu.be/v80-BsYduuc?si=xLCvtuYk-LI_lKWG. A lovely video with great views of Mr. North, the eggs (2:27), the nest

March 8, 2024: News and NestFlix from around our nests!

March 6, 2024: Mr. North appears to be shedding a tear, but it isn't a tear or extra-renal salt removal (which is pretty cool, TBH). It's a remarkably well-placed raindrop!

Congratulations to the Fort St. Vrain Eagles on their third egg! We haven’t passed the solstice yet, but spring has sprung: almost all of the birds we watch are busy laying eggs, tending eggs, protecting territory, courting, and/or copulating right now! We’ve been working hard and hope to have a few cool surprises for everyone in the weeks to come, but in the meantime, kick up your feet, grab a beverage, and soar into the weekend with our NestFlix raptor

March 4, 2024: NestFlix and News!

March 3, 2024: HM on the Y-Branch. She's not nesting here this year, but she doesn't seem interested in letting geese have it, either!

It’s been a busy few days for everybirdy! We have eggs at Decorah North, Fort St. Vrain, and Trempealeau; an ever-changing group of female falcons trying to catch Newman’s attention (Lisa has so far chased them all off); Canada Geese looking at N1 (HM says absolutely not), and falcons showing up at every site we watch. I’m still trying to get band numbers at our sites, so please give me an email if you get one! We’re estimating hatch in

Leap Year eggs for two eagle couples!

February 29, 2024: A second egg for Mrs. T!

Congratulations to two eagle couples! Ma and Pa Jr. laid their first egg at Xcel Energy’s Fort St. Vrain nest tonight, and Mr. and Mrs. T laid egg #2 at Trempealeau! Ma frequently lays three eggs, so if she holds to her usual schedule, look for egg #2 on March 3 and egg #3 on March 6th. We don’t know how many eggs Mrs. T lays since this is our first year of data, but we’ll be watching! Tulsa has
