Cormorant

I took this picture at Dusk and hence the colors. The bird was totally one with the surroundings and sat on that branch for a long time.
It is a cormorant and that explains to me why it was perched on the tree for such a long period of time.
It's wings are not waterproof .They have to spread them out in order to dry them.
The neck differentiates it from an Anhinga. Unlike the Anhinga, the Cormorant does not have a long snake like neck.
