87. SWIFT. _Cypselus apus_, Linnaeus. French, "Martinet de Muraille."--The Swift is a tolerably numerous summer visitant to all the Islands, but I think most numerous in Sark, where hundreds of these birds may be seen flying about the Coupée, amongst the rocks of which place and Little Sark they breed in considerable numbers. Mr. MacCulloch and Mr. Gallienne appear to think the Swift rare in Guernsey, as Mr Gallienne says in his remarks on Professor Ansted's list, "The swift appears here (Guernsey) in very small numbers, but is abundant in Sark;" and Mr. MacCulloch writes me word, "I consider the Swift very rare in Guernsey." I certainly cannot quite agree with this, as I have found them by no means uncommon, though certainly rather locally distributed in Guernsey. One afternoon this summer (1878) Mr. Howard Saunders and I counted forty within sight at one time about the Gull Cliff, near the old deserted house now known as Victor Hugo's house, as he has immortalised it by describing it in his 'Travailleurs de la Mer.' The Swifts use this and two similar houses not very far off for breeding purposes, a good many nesting in them, and others, as in Sark, amongst the cliffs. Young Le Cheminant had a few Swifts' eggs in his small collection, probably taken from this very house, as the Swift is certainly, as Mr. MacCulloch says, rare in other parts of Guernsey. In Alderney the Swift is tolerably common, and a good many pairs were breeding about Scott's Hotel when I was there this year (1878). Probably a good many Swifts visit the Islands, especially Alderney, for a short time on migration, principally in the autumn, as once when I was crossing from Weymouth to Guernsey, on the 18th of August, I saw a large flock of Swifts just starting on their migratory flight; they were plodding steadily on against a stormy southerly breeze, spread out like a line of skirmishers, not very high, but at a good distance apart; there was none of the wild dashing about and screeching which one usually connects with the flight of the Swift, but a steady business-like flight; they went a little to the eastward of our course in the steamer, and this would have brought them to land in Alderney or Cape la Hague. Professor Ansted included the Swift in his list, but oddly enough, considering the remark of Mr. Gallienne above quoted, marks it as only occurring in Guernsey. There is no specimen at present in the Museum.
