Welcome to the fifth year of the Decorah North Eagles. We hope you enjoy watching and learning about bald eagles 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 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.

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

From Chance’s first few falcon flights through family portraits at Decorah North and extremely cool water birds on the Mississippi Flyway, we have your mega-Nestflix roll – along with information about plumage, juvenile hunting skills, those plants at the North nest, and a really cute duckling. A thousand thanks to our camera operators and videomakers for catching and sharing these special moments with us. I hope you enjoy these videos as much as I did! Great Spirit Bluff July 20,
We have NestFlix from Decorah North, Decorah, and the Mississippi Flyway. At Decorah North, DN13 and DN14 show off their newly gained flight skills and squabble over UFO jerky, a deer and her fawns cool off in the stream, and somebirdy fails to stick the landing! In Decorah, Mom keeps us guessing – is she reconsidering her move, or just taking a break from the family? either way, it was great to see and hear her again! The Mississippi Flyway
The US Fish and Wildlife Service is proposing to open seven National Wildlife Refuges to hunting and sport fishing, expand hunting at 83 other NWRs, add regulations that pertain to hunting and fishing, and reduce the regulatory burden on the public (which I interpret as ‘develop a uniform set of regulations where possible’). The proposed regulations may set hunting and fishing seasons, bag or creel limits, methods of hunting and sport fishing, and areas open to hunting and sport fishing.
The Raptor Resource Project will be holding our annual Fledge Fundraiser on Saturday, June 26th! We’ll be celebrating fledglings at Decorah North and Decorah and soon-to-be fledgling Chance (the raptor) at Great Spirit Bluff! You can join us for chat on the Decorah North page, the Decorah Eagles page, and for a QA thread over on our Facebook page! Your donation helps sustain the Raptor Resource Project and all of our nests: the Decorah eagles, the Decorah North eagles, the
We have your NestFlix! At Decorah North, DN13 and DN14 do the Eagle Stomp, continue their flight lessons, and play in the stream. At GSB, nestling falcon Chance sports a cropzilla (Zooey has clearly learned the ins and outs of feeding!) and works on her adult vocalizations as she keks at and tracks something we can’t see. We apologize for the May/June hiatus, although we have some wonderful news! We have banded 79 falcons so far: our best and busiest
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.
