The Western Gull (Larus occidentalis) is the”typical” large, white-headed gull of the west coast of the US. Seen at most beaches, but rarely inland (except at the Salton Sea), this is more of an obligate “sea” gull than other gulls. They breed on offshore islands during the summer, and the Farallones constitute an important breeding location for them. They are the most obvious island resident due to their numbers and their character. Here, a brilliant quote from one of California’s earliest naturalists – William Leon Dawson.
Much that is good and all that is evil has gathered itself up into the Western Gull. He is rather the handsomest of the blue-mantled Laridae, for the depth of color in the mantle, in sharp contrast with the snowy plumage of back and breast, gives him an appearance of sturdiness and quality which is not easily dispelled by subsequent knowledge of the black heart within. As a scavanger, the Western Gull is impeccable. Wielding the besom of hunger, he and his kind sweep the beaches clean and purge the water-front of all pollution. But a scavanger is not necessarily a good citizen. Call him a ghoul, rather, for the Western Gull is cruel of beak and bottomless of maw. Pity, with him, is a thing unknown; and when one of their own comrades dies, these feathered jackals fall upon him without compunction, a veritable Leichnamveranderungsgebrauchsgesellschaft. If he thus mistreats his own kind, be assured that this gull asks only two questions of any other living thing: First, ‘Am I hungry?’ (Ans., ‘Yes,’) Second, ‘Can I get away with it?’ (Ans., ‘I’ll try.’)
[…]Nothing in the life of the Farallons [sic] is more striking than the rapacity of the gulls and their determination to profit by any excitement which will frighten the peasantry.
