lucas said:This looks like the head and neck of a bird or duck to me. I have seen lots of these in ponds and lakes in Florida. It is some type of bird/duck, don't know the name, that dives into the water and its head pops up as it swims along.
Also - I have seen them on land and they are quite funny in the way they sit still for so long and spread their wings. Not sure if they are trying to dry off or what!
I could not see the picture, but the name of that bird is something like comerant.
