There is a pair of Great Horned Owls invading the Decorah nest. Seems they are getting quite cozy at night. The other early dark morning the eagles and the owls had a little tussle. So according to the RRP blogpost below we will just have to wait and see. Mom Decorah is about nearing egg laying time, so who gets the nest and will we be able to watch the eagles this season?
My money is on the eagles.
