Cormorants can be easily confused with the anhinga, but are a more social bird. You’ll often see them hanging out in groups.
The anhinga prefers solitude, and has a longer, leaner frame. Its neck looks enough like a snake that “snakebird” is a colloquial name for the anhinga.
Cormorants do not have the same long necks.
Both birds dive underwater for prey and then retreat to a perch to stretch their wings to dry, since they do not have oil glands to waterproof their feathers.
The hooked bill and orange in its face also help in distinguishing a cormorant from an anhinga.
The most commonly seen cormorant in Florida is the Double-crested Cormorant.
Although in other areas of North American they migrate, in Florida you will see them year-round.
