Visitors are only allowed to stay an hour at a time on Annet during the breeding season, out of consideration for the birds; and the Governor strictly forbids the shooting of the birds or the taking of their eggs. If, in defiance of this or out of curiosity, you thrust your hand into one of the burrows, you will very likely get a piece bitten out of it, and it will serve you right!
The shearwater becomes very eloquent when disturbed in its hole, and pours forth guttural melodies, the sounds of which are imitated in the nicknames of “Cockathodan” and “Crew,” bestowed upon it by Scillonians. Goldsmith compares the disagreeable sound they make when taken to “the efforts of a dumb person attempting to speak.” This bird is largely nocturnal in its habits, resting or sleeping on the water during a part of the day, and fishing chiefly at night.
The guillemot breeds on several of the rocky islands, Gorregan and Mincarlo among the number. It lays its large and beautiful egg on narrow ledges of the bare rock, without any sort of protection, so that it soon gets dirty and can sometimes hardly be distinguished from a lump of clay. But for the long and pointed shape of the egg, which causes it to roll round in a circle when disturbed, it would probably never remain on the ledge long enough to be hatched; for if it were round, like puffins’ eggs, at the slightest touch it would roll over into the sea beneath. The colour of the egg varies very greatly; it is dark blue, a lighter or greenish blue, white, or even claret colour, but always covered with black spots and markings.
The graceful terns, or sea-swallows, visit Scilly in great numbers in the spring, as also do the razor-bills (otherwise known as the common or black auk). The latter may be seen sitting in rows on the rocks in company with puffins and shags. The ledges of rock rising one above another, and the birds sitting on them, have been compared to the shelves and pots of a chemist’s shop. Like the puffin and the storm-petrel, razor-bills rarely leave the sea except for breeding.
The storm-petrel is a visitor in Scilly, and may be seen there “walking on the water” in the strange way peculiar to it; and on account of this habit it is supposed to derive its name from that of the Apostle Peter.
The scarlet-legged oyster-catcher, or “sea-pie,” makes Annet its breeding-ground; as also do many of the terns. The oyster-catcher’s eggs are laid on the loose shingle, and from their close resemblance to the rounded pebbles of the seashore they are not easily noticed, even if you search carefully for them.
Any one who has not before had the opportunity of seeing a breeding-ground of the sea-birds will find a visit to Annet in the early summer quite a revelation, for no imagination could picture these myriads of birds, darkening the air with their wings, as they wheel and hover, screaming, over their temporary home.
