Biology:

Size: Kittiwakes attain the length of 16 inches.
Habitat: The ocean, coasts and isles.

Nest: Nesting is carried out in large colonies, and the birds congregate in March and early April. These sites are crowded with birds and the nests are usually placed on ledges or in crevices. So narrow are some of these , and so apparently flimsy are the nests, that the latter appear to be in constant danger of blowing away or being knocked down onto the rocks below. In fact, the nest is a very strong structure of grass and seaweed mixed with mud and clay, the whole being trodden together to form a firm base. On this more seaweed and grass are heaped until the cup for the eggs rests on a large mass, but many nests are quite compact.

Eggs: The Kittiwake lays a single clutch of eggs comprising 2 to 3 eggs, these are usually laid in May though some have been known to be as late as the first weeks in June. The background colour is lighter than most of the other gulls, being normally a greyish-stone or buff. The markings of the specks, spots and blotches are grey and a dark reddish-brown, and , although varying a little in number, are seldom very dense, but may be grouped in zones.
