Check out this crow’s feet that I encountered in the Roxbury Flock today. Is it Avian Pox? I does not look like other pictures of the pox or birds I have seen. It hasn’t spread to his face or mouth. Or did he walk in something that stuck to him? Hard to tell.
Crows of Arroyos 
I have no divine idea! I’m actually kind of horrified this can happen to a crow (if it is some kind of affliction). I hope someone can provide an explanation.
Yes it was very disturbing to see him. I hope it is just junk on his feet. R
Saw this guy again over the holidays but at least 10 blocks west. Still has weird stuff on his/her feet.
