Eaglet Growth and Development: Week Four

April 19, 2024: DN17 and DN18

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

DN12: Eaglet development at almost two weeks

April 11, 2020: Mr. North and DN12

We’re catching up on videos today, but I wanted to share this footage of DN12 before the roundup. DN12 was 11 days old when this video was made. Eaglets gain roughly two pounds in their second week of life. They experience rapid growth in features like beaks, culmens, and footpads, start replacing their white natal down with thicker grey thermal down, and begin exploring the nest. Although they aren’t yet standing on their toes, they are able to sit up

What are feathers? What is molt?

Feather Follicle

Eaglets go through two molts and three feather stages in the nest: natal down (and molt), followed by thermal down (and molt), followed by juvenile feathers. As of this blog, the Decorah North eaglets are shedding the very last of their natal down and their thermal down is rapidly being replaced by juvenile down and feathers. We thought we would blog a little more about feathers to celebrate!  When we think about feathers, we tend to think about their qualities

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!
