    Part of my confusion is that Sibley shows a Cackling as having a round head and a dark breast which does not apply to the bird in the first photo (more like Richardson's?) and why I have ignored similar birds in the past.

    That is Taverner's Cackling Goose. Richardson's is, far and away, the most frequent and abundant Cackling Goose subspecies in the Lower 48 east of the Rockies. Richies generally have a flat crown; steep forehead; and short, thick-based bill.

    While the close bird in the first photo is somewhat Richardson's like, I don't think that I could rule out Richardson's Cackling x Lesser Canada, and those darned things seem to be becoming more frequent. There is known interbreeding in a bunch of locations where the two subspecies of differing species meet, and it's a long meeting zone.


  2. I agree that it's not a raven of any sort. I cannot see this bird being a Turkey Vulture, either. I don't agree that flapping rules out Golden Eagle. They regularly travel long distances in flapping flight. They cross Lake Superior at Whitefish Point doing it -- shortest crossing = 13 miles.

    Of course, the flapping flight of Turkey Vulture, Golden Eagle, and Common Raven are all utterly different from each other, such that, with extensive experience, one can differentiate amongst them with ease. Video would have been much more useful here.

    I vote for "diurnal raptor sp."
