Double-crested Cormorant

[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.

You can see a cormorant – and hear one. And even watch it wave its wings. All on BirdNote.org.
