The Decorah North eagles are nesting on private property north of Decorah, Iowa. Their nest is located in a white oak tree in a scrap of forest bordering a valley. A stream is located across a field where cattle are pastured. 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.
The eagles 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 in general, please follow this link to the Cornell Lab of Ornithology website.
The male is known as Mr. North. The female is the Decorah North Female, or DNF, who replaced Mrs. North in the summer of 2018. We don’t know exactly how or when it happened. You can read more about it here: https://www.raptorresource.org/2019/01/20/north-nest-announcement/
The first nest at the North site was built in a pine tree. The branches collapsed after the second nesting season and the eagles moved to a dead elm tree. They nested there for just one year before moving to their current location in late 2013. In August of 2018, their nest collapsed and slid or fell out of the nest tree during an extremely heavy storm. None of the tree branches were broken or damaged, so we decided to build a starter nest in the same spot. 2020 will mark their seventh season and fourth nest on this territory.
The North nest is about 56 feet off the ground. It is seven feet long at its longest point, four feet wide at its widest point, is about 3.5 feet high, and has a perimeter of roughly 18 feet.

TLDR: We won’t, but read on to learn why!When will we be able to tell the sex of the eaglets? We get asked this question every year. While most of us make private guesses, we don’t make them official – in no small part because we’ve been wrong before! Keep in mind that age is a bigger factor than sex in weight gain and size early in nest life. Sexual dimorphism begins to appear in some variables after about 20
One of the most common questions we’re getting right now is something along the lines of ‘Why don’t Mom and DM2 DO something about all of those beak-bonking battles?‘ We recognize that eagle parents are bonded to their children, so why don’t they stop potentially harmful behavior? It’s umwelt time, so let’s put our eagle heads on and think through the question! Competition is an important part of eagle ‘society’, but eagles also need to surrender food to hungry mates
It’s April 7 and a lot of you are wondering about the third egg. Will it hatch? It could! It has been almost 34 days since Mom laid her third egg, which is 33 days and 20 hours old as I write this. But her third egg almost always hatches 36 to 37 days after it was laid. If she goes 36 days, which is fairly common, hatch should happen on April 9th. We could see pip later today or
Place, as writer Thom Van Dooren points out, can be understood as an embodied, lived, and meaningful environment. Bald eagles clearly have a sense of place. Their territories are woven with layers of attention, meaning, and experience: spots to hunt, perch, and hide from the weather, materials to build and replenish their nests, and mates and family to bond with and care for. Eagles have neighbors beyond counting – squirrels, mice, raccoon, rabbits, muskrat, mink, coyotes, deer, prairie dogs, trout,
The Chicago Peregrine Program inspired me to write a quick blog on the colors and shapes of eggs. Bald eagles have white eggs, peregrine falcons have eggs that range from light cream through brick red, and red-tailed hawks have pale eggs that are lightly splotched with brown. How and why do the birds we watch lay differently-colored and shaped eggs? In general, female birds inherit egg colors and patterns from their female parents. Egg-shell is made primarily of calcium carbonate,

It’s September! The eaglets have fledged and our eagle Moms and Dads are at their lowest point of attachment to their nests, which makes it the perfect time for camera work. We don’t have a cam turn-on date yet (although I will post as soon as we do!), but here is a rough outline of our tasks: At N2B: We’ll be replacing three cameras and two microphones at N2B, cleaning everything up, and doing a little trimming around the nest
We’re getting questions about the eagle maps. We tend to update them two to three times monthly unless something exciting happens. I’ll put up an update the next time we have data. But in the meantime, we have some videos of a very stuffed DM2, a tween-eagle party at Decorah North, hunting eagles on the Flyway, and a few odds and ends prompted by fan emails. We hope you enjoy these videos as much as we did! Decorah Eagles August
The Decorah and Decorah North cams will shut down for maintenance at 5:00 PM CDT on Saturday, August 29. The chat mods for both cams will be holding special celebratory goodbye chats from 3 to 5pm. Come join us and relive your favorite moments at each nest! Many of you told us that our nests were a place of refuge and calm for you this year. We hope you know that you gave us strength, courage, and determination in the
Where are D34 and DN12? Can the eaglets hunt on their own yet? When will they disperse? Your questions, answered…as best we can! Where are D34 and DN12? The short answer: we don’t know. Neither eaglet has been seen for several days and we didn’t see or hear D34 when we were in Decorah last week. Most of the eaglets that we have studied slowly widened their explorations prior to dispersal. But some (D25 and D1, for example) began adventuring
Grab the popcorn and sit back for some Nestflix (and a link to an article about our peregrine banding work)! We’re starting to see less of D34, D35, D36, and DN12 now that all four tween-eagles have discovered the wonder of flight, but the Flyway is busy – and getting busier – as birds and other animals begin preparing for fall. I liked all of these videos, but it was nice to see Mom and DM2 getting a little personal
Hatching DN11: March 30, 2020 @ 2:36 PM CDT DN12: March 31st, time as yet unknown. Confirmed at 8:23 AM CDT
DN11 died at 5:56 AM on April 10. It appeared to have an obstruction in its throat that it could not clear.
Eaglets and Outcomes
We often get questions about where the eaglets go after they disperse. We have never tracked eaglets from this nest, but we have tracked eaglets from the Decorah nest. For more information, visit our eagle maps.
