The Double-crested Cormorant is a common sight in and around the waters of Florida. It commonly, at least as far as I can tell, is mistaken as an Anhinga (aka: water turkey or snake bird). The main difference being the Cormorant has a larger “duck-like” head and also sits higher in the water. An Anhinga sometimes can barely keep it’s narrow, needle-like head and neck out of the water, hence the name snake bird.
On one of my trips along the Silver River I had a Cormorant follow me for about a mile or so. He would fly right over my head, swim right up to the side of my kayak and then dive and cross under me. At one point, he was close enough to touch. Being that the Silver River is so clearthe made for some great photos.
