January 28, 2019: Decorah Eagles and Flyway Cam Nestflix!

N2B on January 28, 2019

Tonight’s Nestflix feature the Decorah eagles and a really fascinating video from the Flyway cam. In Decorah, Mom chases a subadult, a subadult chases DM2 (check the video out in slo-mo – it is pretty impressive!), and an attempt at copulation ends when Mom walks away in the middle of it.

January 25, 2019: DM2 comes to the nest

Happy Fri-yay, everyone! The weather outside is frightful, but the eagles are delightful! Mom and DM2 have had a busy day keeping squirrels and crows at bay.

January 22, 2019: Female eagle DNF eats a squirrel on the North Nest

Fortunately, the Decorah and Decorah North eagles are well-equipped to handle winter’s snow and cold. Given that a polar vortex is forecast to hit Decorah next week, we might see a little less of the eagles at both nests as they hunker down to conserve energy and stay warm! So what’s going on at the North Nest? A
