Each of the last 2 Octobers I've seen 2-300 crows flying near Pueblo, CO. They are spread out, seemingly migrating towards the southeast.
Twice each year we get flocks of Yellow-headed Blackbirds migrating through Otero County, CO, they hang around cattle feed lots for a week or so. But what I want to know, seemingly they all have yellow heads and are therefore all males. Or am I wrong about that? Where are the females?
