It doesn't appear that it's some kind of injury damage as much as a deformity and, I understand, from A.K.D., (Avian Keratin Disorder). It's hard to believe she, a woodpecker, has survived to adulthood with this bill.

A newly-excavated Red-bellied Woodpecker cavity has been discovered by a European Starling. The male and female Red-bellied are both visible in this photo and the male is trying to pull the Starling out of the nest by its foot.

For my first-ever sighting of a Prothonotary Warbler, (not so common around here), I'd have preferred a more-natural setting than him perched on the windshield of my truck, apparently attracted to Vermont's yellow inspection sticker, but sometimes one doesn't get a choice.
