While looking at ravens on a recent southeastern Colorado CBC, a very experienced birder commented to me that these were likely Chihuahuan as they were in a flock (12-15 birds), and that Common Ravens were generally more solitary in nature. Birds of North America Online touches on this briefly, calling Chihuahuan an "extremely social bird" and that Common Ravens tend to be found "solitary or in pairs."
I've been thinking about this lately as I look at ravens in my part of the state where both species occur, and now this recent Cobirds thread prompts me to ask: Is this something we can reliably consider in addition to the other characteristics we use in trying to separate the two species? And this leads me to a broader question: How much weight can we give behavior in identifying birds generally?
