Double-crested Cormorant Images, Facts and Information:

Nannopterum auritus used to be Phalacrocorax auritus

• Double-crested Cormorants are large, dark waterbirds with webbed feet, long necks, small heads, long, hooked bills and bright green to aquamarine colored eyes. When they are in breeding plumage they have two straggly crests on their heads which can be black, white or a combination of black and white.
• Double-crested Cormorants are migratory in almost all of their range except the deep south. There are exceptions though as I have seen them in Utah pretty much year round.
• Double-crested Cormorants are found throughout much of north America including some areas of Canada and Alaska and into Mexico. Double-crested Cormorants can be found in both saltwater and freshwater environments where there are enough fish to sustain them.
• The diet of Double-crested Cormorants is primarily fish based but they will also consume amphibians and crustaceans. They dive to forage for food.
• Double-crested Cormorants will lay 1 to 7 eggs which hatch in 28 to 30 days. Both sexes incubate and they are monogamous, colonial nesters.
• A group of Double-crested Cormorants can be called a “rookery”, “flight”, “gulp” or “swim” of cormorants.
• Double-crested Cormorants can live to be more than 22 years of age.
