Gibraltar, and Aranei Bay. Probably a few bred on the rock at Gibraltar.
Fulica atra.—A large number of Coots live on the same piece of water at the North Front of Gibraltar as the Mallards mentioned above, where they are apparently semi-domesticated.
Otis tarda.—The Bustard occurs not uncommonly in the south of Spain in the open country.
Gallinago cœlestis.—Snipe are fairly common in the marshes at Arosa Bay in March.
Totanus hypoleucus.—Two Sandpipers were noted—one at Gibraltar in November, and another near Ronda in April.
Numenius arquata.—Curlew were plentiful on the shores of Arosa Bay in the autumn, and a few were also seen in the spring. The last noted was on March 18th, and probably they did not breed in the hills in the immediate vicinity.
Larus ridibundus.—Black-headed Gulls were common at Arosa Bay in the autumn and in the early spring, but all disappeared by the month of May. At Gibraltar this species occurs in great numbers in company with the next.
L. melanocephalus.—The Mediterranean Black-headed Gull was only observed at Gibraltar, and in the autumn of 1898.
L. cachinnans.—Herring-Gulls occur in very great numbers both at Arosa Bay and at Gibraltar. At Arosa Bay, in May, all the Herring-Gulls had disappeared, but probably they have a suitable breeding-place on the coast not far off, for on the weather becoming stormy great numbers returned to the bay.
Rissa tridactyla.—The Kittiwake is very common at Gibraltar, particularly in the winter. It is also observed at sea on the coasts of Portugal and Spain in all kinds of weather, in which it differs from the Herring-Gull. In December, 1899, several Kittiwakes followed the ship in heavy weather about a third across the Bay of Biscay, leaving her at Ushant. Off Capes Finisterre and St. Vincent they were also, in strong gales, both plentiful and active.
Fratercula arctica.—Numbers of Puffins were observed in small flocks in rather rough weather in December, 1899, off Capes St. Vincent and Finisterre, as well as in the stretches in between them.
Podicipes fluviatilis.—A pair of Dabchicks were noted on the
