Always good to take a second, and enlarged, look at the pics.
About the soarers, thanks Ginger for the info about vultures migrating. I didn't know that. So eagles then.
And what I thought might be broken feather is not; it's definitely the end of a limb, easy to see on the enlarged view. Thanks to Matisse for this info.
The sub-adult this morning (10AM or so) was eating something on the perch. Two crows came to harrass, and I got a fair pic of one of them. Isn't it grand to have the rewind feature?
