News and Videos: Decorah Eagles, Decorah North Eagles, and the Mississippi Flyway!

October 19, 2020: Mr. North makes a brief visit to the nest

Welcome to our latest news roundup! In Decorah, DM2 brings in another stick: the second of many more sticks to come. We hope Mom is paying attention! At Decorah North, Mr. North quickly visits the nest, giving us a short but lovely look before he flies out. And at the Flyway, migrating waterfowl fill the sky in their hundreds, or perhaps their thousands. We hope you enjoy these videos as much as we did! Decorah Eagles October 19, 2020: DM2

Getting ready: Fall nestorations!

Annual Daylight Length, Decorah IA

Why are eagle couples in Decorah working on their nests right now? Among non-tropical birds, many activities (reproduction, molt, migration) are linked to daylight length.

October 19, 2020: DM2 begins nestorations

DM2 carried a stick into N2B on Sunday, October 18. As RRP Director John Howe put it, our season starts with the first stick into the nest. For us, it’s like the first gift of Christmas. And he did it so gracefully! Go, DM2 – and good luck impressing Mom with your hard work! Watch the whole video or fast-forward to about 29 seconds to see DM2 fly in.

What is that bird? A Trumpeter Swan!

October 16, 2020: Trumpeter Swan

So how we tell a Trumpeter Swan from the far more common Tundra Swan? Behavior. Our first clue that we were seeing something a little different? There were only two swans. Tundra swans tend to travel in flocks – like snow, a blizzard of white from the north!
