Adult breeding (Alternate) Double-crested Cormorant in flight; Oceanville, Atlantic Co., NJ; April.

Adults have black or dark-brown plumage, with a dull greenish or bronze gloss that may be absent from worn feathers. The orange-yellow skin of face and throat (gular region) is distinctive throughout year. The “double crest” is a poor field mark; these feathers are variable and are fully developed for only a short time early in year. Distinctive in flight with long neck and slender, hooked bill; holds head up, neck slightly bent. Taken 17 April, 2014 at Oceanville, New Jersey.

Adult breeding (Alternate) Double-crested Cormorant; Saskatoon, SK; May.

Adults have black or dark-brown plumage, with a dull greenish or bronze gloss that may be absent from worn feathers. The orange-yellow skin of face and throat (gular region) is distinctive throughout year. The “double crest” is a poor field mark; these feathers are variable and are fully developed for only a short time early in year. P. a. auritus breeds over most of range in e. and central North America; largely migratory, wintering from mid-Atlantic Coast to Gulf of Mexico. Crest, when present, is black and curled. Taken 4 May, 2013, in Saskatoon, Saskatchewan, Canada. The following is a link to this contributor's image via Birdshare: Kirchmeier.

Second-winter Double-crested Cormorant; Moss Landing, CA; October.

Second-winter Double-crested Cormorant with wings open. Spread wing posture may facilitate drying of plumage; cormorants are thought to have wettable plumage that facilitates underwater pursuit of prey. Taken 9 October, 2010 at Moss Landing, California by Brian Sullivan.

Adult breeding (Alternate) Double-crested Cormorant; Downey, Los Angeles Co., CA; March.
