Decorah North Bald Eagles

General Information

Spring Grove Logo

Thanks to Spring Grove Communications for their help bringing the Decorah North Nest to the world!

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. In general, they 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 and dead fish, squirrels, other birds, rabbit, muskrat, deer, possum and anything else they can catch or find.

Eaglets and Outcomes    >>

Year Nest  Eaglets Known Outcomes
2017 DN3 3 – DN4, DN5, DN6 3 eggs hatched. DN6 died of hypothermia
shortly after hatch. DN4 and DN5 survived
to fledge.
2016 DN3 3 – DN1, DN2, DN3 3 eggs hatched. DN3 died of cold and
malnourishment on May 11. Sibling
aggression was a significant factor. DN2
was killed by contaminated prey on
May 25th. DN1 survived to fledge.


We know very little about the adults here, although they are both sexually mature bald eagles and older than five years of age. Click here for a guide to aging bald eagles based on plumage color and patterns.

Nest and Location History

That we know of, 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 late 2013. 2016 will mark their third season in DNN2.

A few statistics:

  • DNN2 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
