I must offer a correction to the previous blog when I mentioned having seen what I thought was a Limpkin.  Au contraire!  Pictured below is what I saw, and it is an Anhinga.  Although many people in our group were quite familiar with them, I don't recall ever having seen or heard of them.  Their claim to fame is that they don't secrete oil to keep their feathers dry post being in the water, so must sit with wings spread to get the same effect.  Also referred to as snake birds, their necks stick out of the water when they swim, resembling a snake.
