Combined Count Data Reveals Shifts in Hawks’ Migratory Behavior

09 February 2017
Bird species’ distributions and migratory behavior are shifting in response to changes in climate and land-use, but surveys that focus on a particular season can cause scientists to miss trends in the bigger picture. A new study from The Condor: Ornithological Applications tackles this problem by combining Red-tailed Hawk counts…

GPS Tracking of Rough-legged Hawks

16 December 2016
Rough-legged Hawks spend the winter throughout southern Canada and the United States, and yet scientists still know surprisingly little about the basic movement patterns of this relatively common arctic-breeding raptor. One reason we know so little is that Rough-legged Hawks are thought to be “broad front” migrants, meaning they are…

Do you know about our new Forest Owl study?

23 November 2016
by Dave Oleyar, HawkWatch International Senior Scientist As cold temperatures finally begin to arrive, I’m entering data and thinking back to this summer and the inaugural season of our Forest Owl Study in partnership with the Earthwatch Institute, and long-time collaborator and friend, Markus Mika, of the University of Wisconsin…

Red-tailed Hawk Patagial Marks

05 November 2016
Do all Red-tailed Hawks show dark patagials? Well, yes, but… Dark patagials (or "patagial bars") is a well-known ID trait for light-morph Red-tailed Hawks, but some show very faint patagials, appearing as if they lack dark "bars" altogether. This is more common with juvenile Red-tails than adults, and with Eastern…

31 October 2016
Text by Ben West It’s a bit hard to believe, but we have less than a week of raptor counting left at the Grand Canyon HawkWatch!  As the season winds down, we are not seeing as many hawks as we did a few weeks ago.  Our two biggest days this…

Farewell from Chelan Ridge

24 October 2016
Text and photos by Jessica Buskirk After a week of thick fog, snow, and blustery wind with the threat of more to come, we sat on the rock for the last time this season.  Migration definitely slowed to a trickle up at Chelan Ridge HawkWatch, but we were blessed with…

Goshawks, Falcons, and Eagles, oh my!

24 October 2016
Text by Casey Weissburg We are now just two weeks away from count’s end here at Yaki Point HawkWatch, and our daily counts reflect the late season.  Our week started out surprisingly big, though, with a late push of straggling migrants; three days over 80, and one even above 150,…

Meet the Commissary Ridge crew!

24 October 2016
Text by Dan Green Well, there are only a couple of weeks left in the season and the Commissary Ridge HawkWatch crew still hasn't submitted a blog post.  Fortunately, this is easy enough to fix.  We've had a pretty good count so far.  We have had above-average counts on most…
