April 30, 2019: Emerging flight feathers on a 26-day old eaglet (D32)

Rain, rain go away! While the eaglets’ thermal down helps keep them warm, it doesn’t shed water very well. This was obvious today as the eaglets cuddle-puddled (in Decorah) and snuggled under Poptent and Mombrella (in Decorah and at Decorah North). We’ve had a few questions from watchers who are worried about development in what seems like an unending season of storms, drizzle, mist, and the dreaded ‘wintry mix’. Are the eaglets spending too much time under their parents to

Eaglet Growth and Development: Week Four

Three plumage stages are visible: natal down (head), thermal "down" (grey feathers), and juvenile plumage

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. D32 and D33 are 26 and 23 days old. During week three (fourteen to twenty-one days), the

Day 25: Casting up a pellet

We’ve got your Nestflix from Decorah and the kestrel nestbox! I liked all of these videos, but don’t miss Mom covering the eaglets with grasses, D32’s enormous pellet, the Sibling Sunday and Eaglet antics videos, and the kestrel shift change. While we still see some dominance interactions, the eaglets are also busy playing with nest materials, preening, watching one another and their parents, and tracking objects in and around the nest. They aren’t standing yet, but their footpads and tarsi

Whatta Season! Ch-Ch-Ch-Changes!!

April 27, 2019: Whatta Day!

By Sherri Elliott What happened to our eensie eaglets and where did these gangly gray pterodactyls come from? It’s only been a few short weeks since the eaglets hatched at Decorah (fish hatchery nest), and at the Decorah North Nest, and we’ve seen them grow from about 3oz and 3 inches long at hatch to about 1 foot now and weighing as much as a 5lb bag of sugar. They not only change from day to day but sometimes the

April 25, 2019: Mom allopreens D32

When were our adorable fluffy hatchlings replaced by big grey dinosaurs? In their third week of life, D32 and D33 are changing rapidly. Their footpads are expanding and turning yellow, their talons have turned taupe (thanks, Robin and Sherri!), their pinfeathers are just starting to come in, and they’ve gone from fluffy white to woolly grey. When weather permits, they’ve also started to shuffle around and explore the nest, play with nest materials, and wreak havoc on our hearts as
