Professor Ansted includes it in his list, but only marks it as occurring in Guernsey.  There are a male and female, in breeding plumage, in the Museum, and also one in winter plumage.

109.  OYSTERCATCHER, Haematopus ostralegus, Linnaeus.  French, “Hiutrier pie.”—­The Guernsey Bird Act includes these birds under the name ‘Piesmarans,’ which is the name given to the Oystercatcher by all the French-speaking fishermen and boatmen, and which I suppose must be looked upon only as the local name, though I have no doubt it is the common name also on the neighbouring coast of Normandy and Brittany.  The Oystercatcher is resident all the year, and breeds in all the Islands; I think, however, its numbers are considerably increased in the autumn by migratory arrivals; certainly the numbers actually breeding in the Islands are not sufficient to account for the immense flocks one sees about in October and November.  There seem, however, to be considerable numbers remaining in flocks throughout the summer, without apparently the slightest intention of separating for breeding purposes, as I have often counted as many as forty or fifty together in June and July.  The Oystercatcher breeds in Guernsey itself about the cliffs.  Mr. Howard Saunders, Colonel l’Estrange and myself found one very curiously placed nest of the Oystercatcher on the ridge of a hog-backed rock at the bottom of the cliff, near the south end of the Island; it was not much above high-water mark, and quite within reach of heavy spray when there was any sea on:  we could distinctly see the eggs when looking down from the cliffs on them, and the two old birds were walking about the ridge of rock as if dancing on the tight-rope; how they kept their eggs in place on that narrow ridge, exposed as it was to wind and sea, was a marvel.  The Oystercatcher breeds also in both the small Islands, Jethou and Herm, on almost all the rocky islands to the north of Herm, in Sark and Alderney, and on Burhou, near Alderney, where I found one clutch of three of the most richly marked Oystercatcher’s eggs I ever saw:  these, as well as another clutch, also of three eggs, were placed on rather curious nests; they were on the smooth rock, but in both cases the birds had collected a number of small stones and made a complete pavement of them, on which they placed their eggs; there was no protection, however, to prevent the eggs from rolling off.  Both in Burhou as well as on the Amfroques and other rocks to the north of Herm, the eggs of the Oystercatchers, as well as of the other sea-birds breeding there, had been ruthlessly robbed by fishermen and others, who occasionally visit these wild rocks and carry off everything in the shape of an egg, without paying any respect to the Bird Act, which professes to protect the eggs as well as the birds.

Professor Ansted includes the Oystercatcher in his list, but only marks it as occurring in Guernsey and Sark.  There is an Oystercatcher and also a few of the eggs in the Museum.
