Chihuahuan Raven: beak view

This raven was one of the very large winter concentration in the Lamesa, TX area. It, and many others I saw, showed very clearly the field marks of Chihuahuan Ravens. This is in contrast to a number of ravens that I see in southeastern Colorado where it is often difficult if not impossible to clearly identify birds that do not vocalize. In this pic the heavy/thick bill with rictal bristles coming almost the distal end of the bill make it clear that this is a Chihuahuan, and not a Common, Raven. SeEtta
