May 8, 2020: Your Fri-yay nest news and raptor movie marathon!

May 8, 2020 RaptorResource

Happy Fri-yay, everyone! We’ll keep the news short and sweet: today Decorah eaglets D34 and D35 turn 33 days old and D36 turns 30 days old, and DN12 at the North nest turns 38 days old – about halfway through an eaglet’s 75 to 80 day nest life! We had our first peregrine falcon hatch at Great Spirit Bluff last night, with possibly more to come, and we also have falcon hatchlings at Dairyland Power Genoa and MPL Hibbard. Thank

First hatch at Great Spirit Bluff!

May 8, 2020 RaptorResource

We had our first hatch at Great Spirit Bluff last night at 11:07 PM! Based on what we are seeing and hearing, we think we have at least one more egg to go. Congratulations to Nova and Newman on their first hatch! Videos May 8, 2020: 1st Feeding – https://youtu.be/mY_w64CcAtQ. Like peaglets, little falcons are always hungry!

Why do we look for pip at the blunt or the thick side of the egg? After hatch begins internally, but before we see it externally, hatchlings pierce the embryonic membrane, stick their beaks into the air

Visitor at Great Spirit Bluff

April 15, 2020 RaptorResource

Great Spirit Bluff had a visitor yesterday! Nina M/04, a 2019 HY Peregrine falcon banded by Greg Septon at the UW-Milwaukee Engineering and Mathematical Sciences building, dropped by the nest box to visit Newman as he incubated eggs. We talked to our Board, who found the whole encounter quite interesting! Dave Kester, Jim Robison, and John Howe all pointed out her non-aggressive body language and behavior, including the adorable semi-chup vocalizations we hear at the beginning of the video, and

April 13, 2020: Nest round-up and Nestflix

April 13, 2020 RaptorResource

As promised earlier today, we have your nest roundup and Nestflix megaroll from Decorah, Decorah North, Great Spirit Bluff, and the Wisconsin Kestrels! The kestrels are back online and graced us with their first egg on Easter Sunday. I’ll take the Easter American Kestrel over the Easter Bunny any day of the year! A huge thanks to everyone for all the love you showed during our hatch celebration last Saturday! It was wonderful to gather with you and we deeply
