We had an intruder at the Decorah North Nest on March 13th. While Dad was in the nest incubating the pair’s single egg, a roughly four-year old female eagle perched on a limb right next to the nest tree. He responded by covering the egg, softly vocalizing, and ruffling his feathers. The whole encounter lasted about fourteen minutes. I approached two eagle experts about the encounter and received some fascinating information and feedback.
