Welcome to the Decorah North Eagles! We hope you enjoy watching and learning with us! Click the livestream to watch and scroll down the page to learn more about the eagles and their surroundings. For branch ID, follow this link.
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.
Decorah North Bald Eagles: DNF and Mr. North
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 56 feet off the ground.

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. DN15 and DN16 turn 25 and 24 days old today. During week three (fourteen to twenty-one days),

For about the second half, it grows flight feathers and starts developing the skills it will need post-fledge. We will focus on week one in this blog. What can we expect in the first week following hatching? Like humans, growing eaglets have developmental milestones.
Altricial eaglets rely on parental care until they fledge. But goslings are precocial: capable of moving around, self-feeding, and leaving the nest shortly after hatch. What does that mean? Read on to learn more! Canada Geese and Bald Eagles: Precocial versus Altricial From Stanford University: A precocial bird is “capable of moving around on its own soon after hatching.” The word comes from the same Latin root as “precocious.” Altricial means “incapable of moving around on its own soon after
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,

We’re so glad we got to spend time with all of you this year – a wonderful year at the North nest and a hilarious, sometimes difficult, but ultimately hopeful year in Decorah! We’ll be shutting down our Decorah and Decorah North streams for maintenance on Saturday, August 20, at 5:00 PM CDT. Please join us for special celebratory chats and an end of the season fundraiser on our website from 3pm to 5pm on shutdown day. We’ll be reminiscing
Today DN15 and DN16 turn 129 and 128 days old. Last year, none of our camera operators reported seeing DN13 or DN14 at the North nest last year after August 14th. That got me curious, since we know the eaglets are beginning to wander prior to dispersal. I took a look at each year’s August map in two sections: one from August 1 through August 15, and one from August 16 through August 31. While most of our eaglets didn’t
Today DN15 turns 123 days old and DN16 turns 122 days old. How much longer will it be before they disperse? To date, we’ve tracked eight Decorah eagles with satellite transmitters: D1 beginning in 2011, D14 beginning in 2012, Four beginning in 2014, siblings D24 and D25 beginning in 2016, D27 beginning in 2017, and siblings D35 and D36 beginning in 2020. While a few of them did things their own way, most of them stayed within a mile of
What’s going on at DNN and Decorah? At Decorah North, DN15 turns 101 days old and DN16 turns 100 days old. As hard as it is to believe, DN15 has been on the wing for 24 days – almost a month! – and DN16 has been on the wing for 16 days. Both of them are becoming strong, proficient flyers, although the place, be it log, nest, or branch, still looks like a wrestling ring every time DNF or Mr.
Join us here to share your favorite North nest memories and say goodbye – for now! – during our final regularly scheduled Decorah North chat of the 2022 season. We’ll be starting at 6PM CT on Saturday, June 25, and ending at 7:30 PM, although we might stay open a little longer depending on how things go. If you’ve enjoyed watching this year – or any year! – please consider making a donation or becoming a monthly supporter. Your support
DN15 hatched some time during the night of March 25 or early morning of March 26. We got our first glimpse at 6:27 AM
DN16 hatched at 4:25 PM on March 27.
Eaglets and Outcomes: Detailed Annual Information
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.
