Double-crested Cormorant
[Nannopterum auritus]
[Length 33 in. Wingspan 52 in.]
The Double-crested Cormorant is brownish black year-round.
In breeding plumage it is a shinier black, with a bright orange gular (throat) pouch.
For a very brief period during the breeding season, two feather tufts (from which the bird gets its name) are visible on the head.
It resembles a Loon as it swims and dives.
The Double-crested Cormorant has one of the strangest breeding ranges of any bird, being found in a ring around North America.
It inhabits coastal waters, inland lakes, and rivers along the west coast from the inner Aleutians to the tip of Baja California and down the west coast of Mexico, along the east coast from Newfoundland to Cuba, across the Gulf Coast to just south of the tip of Texas, and then up the Rio Grande into New Mexico.
It also nests up the Mississippi River to the Great Lakes and across the northern prairies in the midwest and in southern Canada.
The birds disperse coastally and southward in the winter, sometimes gathering in roosts of up to a quarter million birds at some inland lakes.
This Double-crested Cormorant was photographed at Ding Darling NWR, Florida, USA.
