CObirders, This morning about 7:20 I got a quick (5s, from about 75-100m with naked eyes) look at a very large gray falcon flying near US 36 along the E side of Davidson Mesa (Louisville.) It gave the impression of being very bulky, barrel-chested, and broad-winged. Its flapping motion was stiff, shallow, and seemed heavy-winged compared to a prairie or peregrine falcon. I got no view of the underwing or head, unfortunately.
I'm quite familiar with PRFAs and PEFAs and this bird just didn't have the same look. But based on just a quick and fairly unsatisfying view, I am not confident about reporting that there's a gyrfalcon in Boulder County. Still, anyone who happens to be in the area might keep an eye out for the possibility.
