Guillemots, Razorbills and Others

A colony of guillemots on the Isle of May.

Guillemots (Uria aalge) and razorbills (Alca torda) are both members of the auk family. The easiest way to tell them apart is by the shape of the bill, the guillemot has a pointed bill and the razorbill a shorter flatter bill crossed by a white line. Both are present in this photo, two razorbills bottom left, guillemots top and right.

Lesser black-backed gull and two chicks. These gulls are voracious  predators. Special measures using garden canes and tiny wooden tents have been introduced into the tern breeding areas to protect the eggs and chicks from these gulls.

Nesting shags taken on a previous visit to the Isle of May some years ago. Beautiful dark green sheen on the feathers, bright yellow patch on each side of the bill and a crest of feathers on top of the head, distinguish the shag from the cormorant.
