Birdcatcher or Tetrarch spots?
Thanks for posting these!
Was going to post a few more of him, but for some reason my external hard drive that they are on is not working. ACK!!
Oh he was stunning!!! How sad!!
I say those are Birdcatchers. Too perfectly round and way too white to be Tetrarchs IMO.
These are more what I think when I think Tetrarchs (sorry for the image quality, it was a very dark morning and I didn't see him until he was almost gone):
