‘Decorah North’ is a very large bald eagle’s nest in a secluded valley north of Decorah. The Decorah North eagles are nesting on private property north of Decorah. Their very large nest is located in a white oak tree in a scrap of forest bordering a valley and an excellent stream is located just across a field where cattle are pastured. We don’t yet know their nesting chronology, although it appears to be somewhat later than their ‘neighbors’ in Decorah. The eagles eat live and dead fish, squirrels, other birds, rabbit, muskrat, deer, possum and anything else they can catch or find.

A few facts about the nest ~~~

*The nest is 56 feet off the ground

*It is nine feet long at its longest point

*It is seven feet wide at its widest point

*It has a total area of 49 feet

•It is about 5.5 feet high

•The eagles began building it in 2013 so this will be their third year using the nest.

*Using the method listed here (http://goo.gl/WajKSb), The nest’s weight was roughly estimated to be roughly 1700 pounds (using 37 pounds per cubic foot for wood weight). Good thing it is located in a sturdy white oak tree!

[b]A quick note from RRP:[/b] The nest is located on private property and can’t be seen from the road. We are asking everyone to respect the landowner’s privacy (and cattle) and refrain from visiting the nest in person. Thank you.

Nest History


We know very little about the adults here, although they are both sexually mature bald eagles and older than five years of age

We don't know too much about this nest as it is almost brand new. We do know that the nest we are watching now is the third nest built on this territory in six or seven years. We don’t know whether the same pair of eagles have been here all along.

The first nest (DNN0) 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 a white oak tree, in late 2013. 2017 will mark their fourth season in the Decorah north Nest.

We do know a lot about the 2015/16 nesting season at this nest. Some of you may have even watched this nest last year.

2016 – DN1, DN2, DN3
3 eggs hatched.
DN3 died of cold and malnourishment on May 11. Sibling
aggression was a significant factor.

The cam is on and my first scap has no eagles. It's a beautiful fall afternoon and I can hear the cows in the field moo-ing. It does look like the North's have been doing a lot of nestorating. Left thumb up

Videos! We have Mom and Dad North back at home, a very brief nest invasion by what appears to be a hawk, and synchronized preening in Decorah! Thanks as always to the camera operators and video makers for sharing these special moments with us! We hope you enjoy them.

Intruder and Both Parents at DNN: https://youtu.be/FLfL0g6jV_E
The year at Decorah North started with a bang this afternoon when Mom arrived with a hawk in tow! You might want to slow down the video to see it, since the encounter is only about four seconds long. The hawk follows Mom in, but (after dropping a fish at 2 seconds) she quickly rousts it from the nest. Dad flies in across the field at 5 seconds and it is hard for this human watcher not to think she was giving him a look!
