Aptly named, the Great Cormorant is bigger and better than the Double-crested Cormorant which is the standard Cormorant in NC. The Great Cormorants tend to hang out on channel markers and jetties which makes finding them easy. The head is blockier and the throat immediately behind the bill is lighter in color than it's cousin's.
This one was perched just next to the north jetty at Wrightsville Beach, NC. Unfortunately this sign has come down in a storm so now I have to get my Great Cormorants elsewhere.
