Larus fuscus
A common resident.
Not so numerous as the Herring Gull, this species is nevertheless, well represented in Pembrokeshire, and nests upon the various islands, selecting the ground on the topmost slopes of the cliffs, and there breeding in small societies of from twenty to thirty pairs, apart from the other Gulls, in places where it is perfectly easy to walk among the nests, and to admire the beautiful clutches of eggs. This Gull is also a greedy stealer and devourer of other birds' eggs, young rabbits, &c, and like the Herring Gull, comes far inland, visiting the meadows in the spring, at which season we always saw some in our fields at Stone Hall, in company with the Common and Herring Gulls.
