I asked our moderators for their top questions of the day. You wanted to know: ‘When will DM2 start feeding his young?’. This is our answer. Note: The morning after this blog was written, D32 did his first feeding!

We’re going to talk about what DM2 is doing first:

Falcons are back at almost every spot, we’re seeing Tundra Swans, Sandhill Cranes, Common Goldeneye ducks, and other migrating waterfowl at the Flyway, Peregrine Falcon Newman is bringing food gifts to mate Michelle, and background birdsong can be heard almost all of our nests. If any of you are good at birdsong ID, please get back to me – we’re looking for someone to help us figure out what we are hearing!

Heat is exchanged, warming the blood flowing into its core and cooling the blood flowing into its feet. The cooler blood
As I’m sure most of you know, we lost an egg in Decorah today. We’re getting a lot of questions about how the eagles respond to loss and how they might feel about the broken egg. It’s a complicated question that we plan to write about tomorrow. In the meantime, it was nice to see Mom and DM2 caring for the remaining two eggs – gently turning them, shimmying over them, and covering them on a warm, bright day. Our
