We built a back yard from scratch with native plants, for the purpose of bird photography and human use. We started in May 2021 and already it has brought us a lifetime of enjoyment. Here in a St. Paul, MN suburb we have a lot of migrating species. I've recorded 65 species in the back yard and another 20 flying over or swimming next door. I believe the project has taken 15 years off my life, from retirement age to being a kid again. Well, that isn't 15 years, but you know what I mean.
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?
