Mystery Solved

Well I think my questions have been answered. After receiving a number of replies to my questions, the majority opinion was that the crow was suffering a case of avian pox. Some folks offered other possibilities and I am impressed by the depth of knowledge that people possess and are willing to share.

The bird reappeared this morning and the growth has disappeared. I was able to get a couple of shots that show an open wound where the growth was. Again, the bird seemed none the worse for this and was happily feeding with its sibling and parents.

Profiles from both sides show a sore that looks like it was centered just above the base of the upper bill.


The photo below has been enhanced a bit to brighten the image and is the best image I have of a frontal view of the wound. All in all a pretty interesting few days following this individual.


My sincerest thanks to all of the wonderful people who weighed in on this question. I continually learn from you and realize that I will never know enough to be satisfied so don't be surprised if you see a new question soon!
