Double-crested Cormorant
People often wonder how the Double-crested Cormorant got its name since it does not usually display a crest, much less two crests. However just prior to breeding they grow out crests above each eye. Usually black, but sometimes white. This is presumably the Pacific Coast race "N. a. albociliatum" characterized by a straight (not curled) crest, variable crest color and smaller size. Formerly placed in the genus "Phalacrocorax."
