Cormorants, like this double-crested, have no natural oils to apply to their feathers to prevent them from getting waterlogged. Other water birds don't have this problem and the term "water off a duck's back" comes from that fact. So this is why you see cormorants drying their plumage in the sun like this. When their feathers are full of water they become heavy and flight is difficult.

The body of the bird seems to be lacking detail - it looks pretty near solid black to me - but maybe I just can't distinguish the variation. Perhaps the head was a little softer than the wings - interested to know what the point of focus was. There seems to be a little bit of a sharpening halo around the bill and the left wing.
