Double-Crested Cormorant

What are they doing with their wings like that?

Sitting on a piling, wings outstretched, the Double-crested Cormorant looks like a black Celtic cross. Cormorants dive from the water's surface, pursuing prey under water, propelled by powerful webbed feet. The male performs a flashy wing-waving display to show off his colorful head-tufts and neck. When not nesting, Double-crested Cormorants are a common sight near fresh and salt water.

Double-crested Cormorant

Adapted from a script by Frances Wood


This is BirdNote.
[Guttural sounds of Double-crested Cormorant colony]
These deep, guttural sounds are coming from a nesting colony of Double-crested Cormorants.
[Guttural sounds of Double-crested Cormorant]
Large black waterbirds with short legs and long necks. Look closely and you can see the bird’s “double crest” – its two long, gloriously feathered eyebrows. When not nesting, Double-crested Cormorants are a common sight near fresh and salt water. They often sit upright on a rock or piling, holding their wings out to the side, resembling a black Celtic cross. During courtship, they may wave their outstretched wings.
 [Guttural sounds of Double-crested Cormorant]
Why do they have such a limited and guttural vocal range when many birds create glorious songs? Well, it has to do with the number of muscles a bird can use to govern its vocal organ, the syrinx. The more you have, the more elaborate the sound. Many song birds have five to seven sets of these muscles. The cormorant has only one.

And a last fact about the cormorant – it’s featured on the logo of Seattle Audubon* – where BirdNote originated. Today [April 17, 2016], we wish them a Happy 100th Birthday.
