On the eastern coast of England, the guillemot is best known by the name of Willock.
The birds comprise a darter, a cormorant, a guillemot, and a penguin.
The guillemot lays a single egg, without making a nest of any kind for its reception.
The guillemot makes no nest, merely laying a single egg on a ledge.
Thus the Herring-Gull occupies a comparatively small area, though one which is many times larger than that of the guillemot.
Its actions in the water are almost precisely the same as those of the guillemot.
The guillemot makes no nest, lays but one egg, and incubation lasts about a month.
Like the guillemot it breeds abundantly on the Shiant Islands.
The guillemot breeds on several of the rocky islands, Gorregan and Mincarlo among the number.
But, indirectly, its behaviour would affect the guillemot race.
