Double-crested Cormorant

When I took this photo near Dallas, Texas, this spring, I was not positive as what kind of cormorant this one was. The facial skin is yellow like a Double-crested Cormorant, but its bill seems more the size of a Neotropic Cormorant. The Neotropic, however, should have a more distinct white line behind the bill. Likely this individual is a juvenal Double-crested Cormorant molting into adult plumage, since young cormorants often have smaller bills than do adults. In any case, the yellow face is diagnostic of Double-crested Cormorants.
