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
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. We’ve primarily discussed the photosensitive period of bird life here, when daylight lengthens, gonads start swelling, and human watchers start counting the days until eggs are laid. However, birds also have a photorefractory period that in many northern birds begins slightly prior to summer solstice in mid-June. Gonads start shrinking, a new hormonal regime takes

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? It is a Trumpeter Swan! Our eagle-eyed camera operators found it yesterday on our Mississippi Flyway cam and we went to ornithologist Tom Prestby for an expert opinion. 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!
