But not everyone accepts the conventional wisdom. In the spring of 2013 I was birding in southeast Colorado for the first time. It’s the least you can do. Interestingly, the most Chihuahuan-sounding Commons I’ve found are mostly from California: You may recall that over a decade ago, Common Ravens in California were found to be genetically distinct from other Common Raven populations — more closely related to Chihuahuan Ravens than to other Commons. Both parents bring food for nestlings. In treeless terrain, they often build their nests on the crossbars of utility poles. At northern end of range (eastern Colorado, western Kansas), far less common today than in 1800s. When in flight their necks appear longer than that of a crow.
