Most people look up when someone exclaims, "Look at that bird!" If they
are talking about a Cormorant though, you might have to look down
beneath the water to see the bird they refer to.
Double-crested Cormorants plunge their head into the water and vanish
beneath it. They are diving birds. I also see
swim this way.
Then, sometimes a surprising distance away, their head will pop back out
of the water.
Double-crested Cormorants are a frequent sight perched, wings spread, to
dry on the bird shaped
sprinkler pipe floats in South Florida water retention ponds.
I really like their blue eyes, but I seldom get close enough to get a
good look at them.
