It was a quiet morning at Corkscrew Swamp Sanctuary near Naples, Florida until the Anhingas started to squawk. They are usually quiet birds, but I discovered that when they cry out, they can be loud. (Click here to hear one.)
Sometimes called the “snake bird” because its slender neck often curved in an S shape looks like a snake when it sticks out of the water when they swim underwater, and pop its head out to breathe. Since females have brown necks, this one appears to be a male. They are also quite large (wingspan 42″) and are commonly seen in Southwest Florida and the Everglades. Black and white feathers on the mature Anhinga resemble piano keys.
This one had a lot to say. He seemed panicked as though he was putting out a danger call. Perhaps there was a bobcat or a vulture in the area.
