This Shag was enjoying the sunshine on the Menai Straits this week. Although it's not the world's greatest photo, you can tell it is a Shag rather than a Cormorant in several ways.
Although both birds are very similar to the untrained eye, the Cormorant is a much larger bird - this one is relatively small, even for a Shag.
It has a steep forehead as opposed to a Cormorant which has a long, sleek sloping forehead
There is little or no white on the throat or body which would be evident on a Cormorant.
The plumage is far too light to be a Cormorant which are much darker and almost black in appearance, although Shags develop a dark glossy green plumage in the breeding season along with a prominent recurved crest on the front of their head.
