Just finished a fantastic trip to Yellowstone National Park! (Thank You Park Service - America's best idea!). Lots of cool predators (wolves, coyote, fox, grizzly, black bear, badger, lots of raptors). My favorite raptor photo - Red-tailed Hawk with Uinta Ground Squirrel. #BirdsofPrey #raptors

(1/2) My latest research manuscript (my 20th!). This study provides important insight into an emerging disease affecting Sharp-shinned Hawks. #raptorResearch #BirdsOfPrey meridian.allenpress.com/rapt/article...

Our introduction to raptor handling and banding workshop registration is open. Workshop is held in Idaho, USA in September, led by yours truly. (birds handled with all necessary federal, state, and local permits). Details: www.boisestate.edu/ibo/2025/03/...

We hear lots of news about golden eagle mortality by wind turbines. However, this is not the largest source of mortality in the western US. Any guesses? Illegal shooting... Needless and disgusting! (Katzner et al. 2020, Millsap et al. 2022) #birdsofprey #raptorResearch #conservation #Birds

Golden Eagle (Aquila chrysaetos) talons. Respect! Idaho, USA 2020. #talonTuesday #raptorResearch #birdsOfPrey #birds

Our paper accepted for publication in J. of Raptor Research. Will share link when online. Erickson, Mathiason, Alioto, Allen, Crocker, Miller, Nicoletti, and Radley. Oral Capillariasis in Sharp-shinned Hawks (Accipiter striatus) During Fall and Spring Migration #raptorResearch #birds #birdsOfPrey

Great afternoon walk along the Boise River (Idaho, USA). My best two photos - Common Merganser and Bald Eagle. Both eagles were within 100 m of the nest that they have been working on.

Young Cooper's Hawk (Second-Year, ~8 months old) in our local nature reserve. We saw an adult about 500 m away, but no photos. #birds #raptors #birdsOfPrey

Surreal to be at a musical about our country's founding while it is currently being torn apart. But, this is our most anticipated show of our season tickets. #Hamilton #broadwayInBoise #dateNight

As a cancer patient, and a human being, this is disgusting. I used to have UHC insurance (the worst I have ever had). I even won a class action lawsuit on one of their previous "screw the patient" schemes.

American Goshawk, "Purple 2U" (color band not visible) is at least 9 years old. Banded in 2018 as full adult. She has successfully raised young in all but 1 year since 2018, almost always having 3 offspring. Can't wait to meet up with her again in June. #Birds #RaptorResearch #addBirder

As part of my job I manage a number of projects for surveying woodpeckers. Within the Boise National Forest (Idaho, USA) we survey for Pileated, White-headed, and Black-backed Woodpeckers. Here is a photo of a Pileated Woodpecker I took in May of 2023. #woodpeckerWednesday #Birds

I am glad that I evicted the invasive squirrels yesterday, as a Western Screech-owl decided to check out my nest box this morning. They checked it out last year, but didn't end up using it, although they spent more than a couple months in our yard after they fledged! #birds #birdsOfPrey #Owls

Broadway in Boise date night!

Awesome work by one of IBO Team Goshawk's collaborators. We contributed blood samples from our adult and nestlings goshawks to help in this effort. Congratulations! www.boisestate.edu/news/2024/11...

Wow, way to counter the industry trend and actually support students!

White-headed and Hairy Woodpeckers sharing a branch. The Hairy was clearly dominant marching the White-headed off of the branch. This was consistent with my other observations of these two species interacting. April 2015, Boise National Forest, Idaho, USA. #WoodpeckerWednesday #birds

Wowza, get your molt on! A Second-Year Peregrine Falcon. Safely trapped, banded, and released by trained professional with all necessary federal, state, and local permits. Fall migration, Idaho, USA. #FalconFriday #birds #RaptorResearch #BirdsOfPrey

Awesome first day out on skate skis this season. Have a great weekend all!

Wow, mind blowing perspective of the day. I had always considered feather mites to be a parasite with deleterious effects.

Great training photo on Accipitriformes molt progression. Second-Year (1-year-old) breeding female American Goshawk. June 2024, Idaho, USA. #raptorresearch #goshawksRule #kakkakkak Bird trapped, banded, and safely released with all necessary local, state, and federal permits.

Nice contour feather molt around the face of this Hatch-Year Red-tailed Hawk. A couple on the back as well. Idaho, USA, November 22, 2024. Bird was trapped for research project. Bird trapped, handled, and safely released by trained researchers with all necessary local, state, and federal permits.
