Cormorant

A shot from Manasquan Reservoir
(300 f/2.8 + 1.4x + 2.0x TCs; on tripod - i.e., 840mm, f/8, 1/250s)

I think from looking at Peterson's guide that this is a Great Cormorant (Phalacrocorax carbo).

The entire frame, resized:


100% crop: I think with some practice the exposure can be sharper.
