JM Verbeek 1966 Talco rusticulus 28 Aug In the Britton Area Tom Custer and I noticed a gray bird sitting on a mound. With the unaided eye I thought it to be an owl (snowy) but when I looked thru the scope the bird turned out to be a Gyr falcon. When we tried to get closer the bird flew and soon caught my with a flock of Glancous Gulls, at one of which he made a pass. He then continued flying low over the ground for some distance, after which I lost him in the fog. Tom thought it to be the Rough-legged Hawk he saw a few days ago, but the gray color and the fact that it made a pass at a gull as well as the typical falcon like flight close to the ground make me certain that it was a Gyr falcon.
