Meet the Fort St. Vrain Bald Eagles

March 18, 2026 RaptorResource

The Xcel Energy Fort St. Vrain camera is located in a cottonwood tree near Platteville, CO, on property owned by Xcel Energy. We’ve been streaming this camera – or at least uploading photos – since 2003, making it one of the oldest eagle cams on the internet. It isn’t part of our explore.org family, so eagle fans tend to be a little less familiar with it. Live stream here: https://www.raptorresource.org/birdcams/xcel-energy-cams/ The Area As the eagles look out from their nest,

What’s on the Menu at Fort St. Vrain?

March 18, 2026 RaptorResource

What’s on the menu at the Fort St. Vrain Bald Eagle nest? Back in 2017, we collected prey remains from the nest. We didn’t have permits to take feathers – of which I found only two, both belonging to prey – but there were plenty of skulls and a few turtle shells. We found 35 fish remains (skulls, skull fragments, opercular bones, jawbones, and an otolith), seven prairie dog skulls and one foot, one desert cottontail skull, one common muskrat

Happy St. Patrick’s Day From the Raptor Resource Project!

March 17, 2026 RaptorResource

Happy St. Patrick’s Day to our friends near and far! May you always have walls for the winds, a roof for the rain, tea beside the fire, laughter to cheer you, those you love near you, and all your heart might desire! In celebration of the day, we wanted to share an osprey conservation story from Ireland. In 2023, Ospreys bred in Ireland for the first time in over 200 years: https://www.ulsterwildlife.org/news/ospreys-breed-ireland-first-time-over-200-years. Reintroduction efforts include monitoring, releasing, reporting, and satellite

Bald Eagle Pa Junior Found Dead

March 16, 2026 RaptorResource

We are sorry to announce that Bald Eagle Pa Jr. was found dead late last year in the far northeast corner of Xcel Energy’s Fort St. Vrain plant. Xcel Energy reported his death to Colorado Parks and Wildlife (CPW) and the U.S. Fish and Wildlife Service. An autopsy conducted by CPW indicates that electrocution may have been a factor. This is the first reported power line incident here. After the autopsy, Pa Jr.’s remains were sent to the National Eagle

Peek inside a bald eagle egg: 11 days!

March 16, 2026 RaptorResource

What do embryonic eagles look they look like as they develop and grow inside their eggs? Dr. Peter Sharpe from the Institute for Wildlife Studies developed a table of bald eagle embryonic development based on work done by Hamburger and Hamilton (1951). While not all bald eagle eggs hatch in 35 days, the stages of development look something like this… When we last peeked inside the egg, our embryonic eagle had inner and outer layers, a developing circulatory system, a

What Makes Bald Eagles Incubate?

March 9, 2026 RaptorResource

What makes a Bald Eagle incubate? While birds can perch for hours at a time, incubation takes the art of sitting still to an extreme. Read on to learn more! Hormones, egg production, and broodiness As daylight length increases, birds’ gonads swell. Both sexes produce testosterone, although male birds produce more than female birds. Testosterone is associated with aggression, territoriality, courtship, nest-building, testicular development, and sperm production. Female birds also produce progesterone, aka the “pregnancy hormone”, which induces egg production.

DNF Laid An Egg!

March 9, 2026 RaptorResource

DNF laid her first egg of 2026 on Saturday night at 6:35 PM. As far as we know, DNF and UM haven’t copulated, so if this egg is fertile, it was fertilized by Mr. North. Female raptors can store sperm for up to four weeks and possibly longer – well within the fertility window, since Mr. North disappeared on February 25 – so any eaglet that hatches from this egg must have been sired by him. Does UM know the

Who’s That Bird? It’s a Short-Eared Owl!

March 3, 2026 RaptorResource

A Short-eared Owl visited our island at the head of Lake Onalaska on Sunday. One of the world’s most widely distributed owls, the Short-eared Owl is an open country, ground-nesting species that inhabits marshes, grasslands, and tundra throughout much of North America and Eurasia. What was it doing out during the day? Short-eared owls are active day and night. The reed covered islands at the head of Lake Onalaska provide excellent winter hunting for this and other species associated with
