Flock of Somethings

I was under a trailer trying to weld something but instead was getting red-hot embers in my ear hole, so I threw off the mask and looked up to see this squadron of largish bird creatures flying by.

Maybe they're vultures on their way to a guy crawling across a desert. But there were over 30 of them cruising together. I'm no ornithologist, I'll just admit that right off the bat. But the closest one looked hawkishy to me. Hawks don't fly in giant wads, do they?

This here is a zoomed in version and I messed with the contrast and whatever to try to get the silhouettes. Didn't do to great a job, but this was a camera phone.

Here's a zoomed out version showing most of the pack.

I'm not crawling across my lawn calling out for water until this matter is settled.
