What’s going on at Great Spirit Bluff?

June 9, 2021: Zooey sits up high to brood

What’s going on at Great Spirit Bluff? Why isn’t Zooey feeding her young? Why doesn’t Newman taken over? And what’s up with Zooey’s shuffling? We turned to Board member and Gyrfalcon breeder Jim Robison to help answer your questions. Although it isn’t true in every case, first time falcon mothers are more likely to be reticent about feeding, to fumble food, to eat dropped food, and/or to feed inappropriately-sized bites to their hungry young. Zooey stashed and prepared food and

News, nestflix, and itsy-bitsy spiders!

March 15, 2021: Mr. North incubates eggs during the March 15 storm.

Snow, snow, go away! Mr. North and DNF rode the storm out after six inches of snow fell on the North nest. We’re looking forward to warmer, drier weather for the rest of the week, which should melt the snow fast: a good thing, since we think hatch will start here in about 13 days! In the meantime, we’ve got wonderful close-ups of the two incubating, nice looks at the eggs, date night, and an itsy bitsy spider piggybacking on

Nothing Goes to Waste

March 16, 2021: Ma and Pa Jr. on the nest, Fort St. Vrain, Platteville CO

Xcel Energy’s Fort St. Vrain eagles rode the big storm out last weekend. Despite an astonishing twelve or so inches of snow, Ma kept the eggs covered through most of it. Male and female eagles both incubate eggs, but females usually cover the nest at night and through bad weather. A female eagle’s larger body size and brood patch helps her stay still for longer periods of time and apply more heat to the eggs and young beneath her. Unfortunately,

March 9, 2021: Territorial Battle At Great Spirit Bluff

March 9, 2021: Territorial battle at Great Spirit Bluff

On March 9 at about 6:37am central time, GSB watchers witnessed a peregrine falcon territorial battle. Resident female Nova came back after a three-day absence and drove interloper Nina away. After ousting Nina, Nova copulated with Newman and disappeared again. Are the falcons okay? Neither falcon appeared to have been seriously injured in the fight. We zoomed in on Nova’s eyes – our primary concern – and they appeared to be fine. Either Nina or Nova could come back to

The Hatchery Maple Tree

As many of you already know, the Iowa DNR took the maple/perch tree on the hatchery grounds down on February 18. We had recommended a fall removal, but that was not possible. The DNR was compliant with federal law regarding work near an eagle’s nest, held a public meeting on the tree removal, and took a great deal of care to get the tree down and taken away as quickly as possible. RRP Board Member Dave Kester monitored the situation
