This Rough-Legged Hawk (Cornell link) is one of the only three American raptors with feathers all the way down their legs to their talons (not including owls). The other two are the Golden Eagle and the Ferruginous Hawk. All three of these birds live in areas with extreme cold, and over hundreds and hundreds of years their bodies have adapted.
Rough-Legged Hawk Legs Close-Up
I had a great time just a few minutes before sunset yesterday up in Sax-Zim Bog. The large raptors are arriving from the Arctic. Rough-Legged Hawks will hang around in Northeastern Minnesota till the snow piles up on the ground (hawks don’t like to hunt through snow). Given the sun which was extremely low to the horizon and was in the hawk’s eyes, even though I was close it could not see me as it hunted.
