Where did the Decorah Eagles go? They built a new nest at a location that is out of range of our cameras. We will report on them but, depending on where they nest, we may not be able to watch them live. However, Mr. North and DNF are very busy preparing for eggs at the Decorah North nest. You can watch and chat here and we’ll keep everyone posted. https://www.raptorresource.org/birdcams/decorah-north-nest/.
About the Decorah Eagles
The Decorah eagles are nesting near the Decorah Trout Hatchery, located at 2325 Siewers Spring Rd in Decorah, IA. The female is known as Mom and the male is known as DM2. 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. They 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, please follow this link to the Cornell Lab of Ornithology website. Visiting Decorah to see the eagles? Please read through our guide to eagle etiquette >> Bald Eagle Etiquette.
Female eagles are larger than male eagles, with slightly darker heads and more pronounced brows. The image below shows the differences in appearance between Mom and DM2 and should help in ID’ing them.
History of the Decorah Eagles
Dad, Mom’s original mate, disappeared in April of 2018. Based on plumage color, Mom was four years old in 2007, making her eighteen years old in 2021. Click here for a guide to aging bald eagles based on plumage color and patterns.
After two other males came and went (you can read more about that here), Mom accepted a third suitor in the fall of 2018. She and DM2 are entering their third season together.
Nest Territory and Locations
Four nests (N0, N1, N2, and N2B) have been built on the Decorah territory. N0 was destroyed in a storm, the eagles left N1 on their own, and N2 was also destroyed in a storm. Fourth nest N2B is a little more complicated. Humans Neil Rettig and Kike Arnal built N2B in August of 2015. We hoped the starter nest would encourage the eagles to adopt it and keep building, which they did! Footage of the build can be seen here: https://youtu.be/2-xRSBBeIYs. A blog about the nest build can be read here.

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 three in this blog. DN13 and DN14 are 18 and 16 days old. During week two (seven to 14 days), the

What can we expect in the first week following hatching? Like humans, growing eaglets have developmental milestones.
How do we know that falcon Zooey is two years old? Peregrine falcons have two distinct age-related plumages: juvenile and adult. Juvenile falcons have heavily barred underparts and brownish topsides (“brown birds”), mature falcons have pale undersides with black-barred bellies and blue/slate topsides (“blue meanies”), and two-year-old falcons like Zooey have a mix of adult and juvenile feathers. I love this stage! Tail Feathers (Retrices) Like all peregrine falcons, Zooey has twelve tailfeathers that are numbered one to six from
We are on hatch watch at Decorah North! While both eaglets still have open body cavities, most of their major morphological changes are done. At this point: Their eyelids still need to close all the way. Their eyes are growing into their sockets, more or less. Eaglets often have big bulgy ‘blueberry eyes’ when they hatch. Their eyes settle into their sockets during the first few days after hatch. Natal down is growing from feather germs. The chicks are squirming

This video shows DN13 (left) and DN14 (right). DN13 fledged on June 11, at 78 days of age. When will DN14 fledge? Our little eaglet turned 82 days old on June 17, which prompted us to look at previous fledges! I’ve included sex where verified by measurements. While males fledge earlier than females on average (Brett’s study found that males averaged 77 days and females averaged 78 days) some males fledge late, as you’ll see below. Is DN14 the latest
It’s been a very busy few weeks! Since May 20, we’ve banded 73 falcons, cheered DN13’s fledge, said goodbye to the Wisconsin kestrels, treated the lone nestling falcon at GSB for ectoparasites, and watched an unknown young adult eagle check out N2B. Thanks so much for watching, sharing, learning, and caring – and for your patience during our busiest season! We’re wrapping up our sites this week and will be returning to our regular program of video round-ups, eagle travelogues,
Story and photos by Robin Brumm I spent Memorial weekend with the Decorah eagles. Since it was a multi-day trip, I will spare you a 3-page report, and just tell you a few of my favorite things. On the first day I was there, I was sitting talking to Mom and the eaglets, because what else is there to do??!! Too bad they couldn’t hear me since I was so far away! As I was watching, Mom jumped up, spread
. Story and photos by Robin Brumm I last went to Decorah 2 weeks ago, so of course, I had to go on Saturday. RRP believes that the eaglets started hatching around April 4th or 5th. That would make D37 about 6 weeks old now. The eaglets grow so fast, I didn’t want to wait too long to go visit. I think I picked the gloomiest day to go, but any time I get to see the DE family is
We’ve seen a Canada goose nesting up on hatchery rock for at least the last couple of years. But now one is interested interested in N2B! It appears to be checking out the nest pretty seriously at 5:54, settling into a shallow depression and taking the nest bowl for a brief spin before flying out. Did the goose create the scrape? While we didn’t see it on camera, we think it did! We checked over past footage and did not
Decorah Eagles 2021 Nesting Record
Hatching Hatch began on April 4th or April 5th. Robin Brumm confirmed three nestlings on April 16.
Fledging Fledge should occur in mid-June.
We often get questions about where the eaglets go after they disperse. We tracked eaglets in 2011, 2012, 2014, 2016, and 2017 to try to answer this question. For more information, visit our eagle maps.
