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/.
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.
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.
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

By Robin Brumm Monday was my last day of spring break. Hmm…what should I do?? Go to Decorah, of course! I spent Friday and Saturday and there were no signs of a hatch either day. I know that the eggs usually hatch at 35-40 days old. I had looked at the nest records and noted that for the last three years, the first egg has hatched at 39 days. If they laid the first egg on February 24th, 39 days
This is a flashback post first published on April 26 of 2012. I repost it every year when the eagles begin bringing suckerfish into the nest. For new followers: Bob (Anderson) founded the Raptor Resource Project and was its first director. You can learn more about him here: https://www.raptorresource.org/about-us/remembering-bob-anderson/ Bob took a turn operating the controls at the Bald eagle camera this morning. He was fascinated by Dad, who brought in three suckers in one hour. Suckerfish are ‘rough’ fish:
Somebody stopped by the Decorah Air Branch & Breakfast on April 1 at around 8:20am. Robin Brumm writes: “There was quite the beauty that stopped by N2B and the maple (M2) this morning. I’m guessing that it is about 3 years old. I know we all would like it be one of Mom and Dad’s offspring, but unfortunately, we will never know, because they refuse to wear name tags!” We haven’t seen Mom or DM2 in a few days. While
We have your Nestflix mega-roll, with videos from Decorah North, Decorah, and the Flyway! At Decorah North, DNF dines on cowghetti, flies past some deer, and gathers grass to replenish the nursery. It won’t be long until eaglets at here! In Decorah, Mom eats a light fish dinner, letting prospective inhabitants know that this eagle branch and breakfast isn’t for rent! And pelicans – a marvelous, magnificent sign of spring – return to the Flyway today, resplendent in their beautiful

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.
