Western Gull (Larus occidentalis)

A Western Gull egg was collected on San Miguel Island by Amelia Read circa 1888. This is extraordinary on several fronts: this is the only known avian specimen collected on a California Channel Island by a woman; it was collected in about 1888 before almost any other avian specimens were taken from any island!

The oldest breeding Western Gull known of record — who holds a 34 year record — was banded in 1973 on Southeast Farallon Island.

“Western Gull (Larus occidentalis) numbers and breeding localities have been poorly documented on this [ ] as well as on other Channel Islands. Willett (1910) states they were “breeding commonly on all outlying rocks and islets” of the northern islands, and Howell (1917) calls them “abundant residents, breeding on all the islands...”. Streator (1888) found large numbers there in 1886. H. S. Hendrick collected a set of eggs on Prince Island on 5 June 1905 (Peyton unpubl. notes in WFVZ). Appleton (unpubl. notes found 80-100 pairs, but few actual nests on 6 June 1906. He collected seven egg sets, one of which in in WFVZ (63502). Willett's party collected three sets on Prince Island on 15 and 17 June 1910 (WFVZ 3406 and uncat.), and Wright and Snyder (1913) observed breeding birds here in July 1912. Egg sets were collected on Price Island on 3 June 1928 (WFVZ 2680). 25 May 1929 (SBM uncat., two sets) and 11 June 1933 (WFVZ 65914-65916), and Sumner (1939) observed breeding birds on Prince Island on 18 April 1939. The POBSP (Huber 1968) counted about 400 nests at San Miguel Island in 1968; ca. 240 on Prince Island., 100-150 nests on Castle Rock, and ca. 50 nests on the main island.” [Marine Mammal and Seabird Survey of the Southern California Bight, Volume 3, Issue 3. University of California Santa Cruz et al., July 1978]

SANTA BARBARA ISLAND

1897 Santa Barbara Island: “Larus occidentalis—Western Gull. This bird was noted everywhere we went. A small colony were breeding on San Nicolas Island, and immense numbers on Santa BArbara Island. On the latter they were nesting on the outer margins of the mesa, nearly the whole way around the Island. A good many were nesting on the sides of the hills in the center of the island. Full sets were of three. On May 18, about twenty sets of fresh eggs were collected, but as yet only few of the nests contained full sets. The nests were slight depressions among the weeds and grass, with a scanty lining of dry plant stems and grasses. One Western Gull from Santa BArbara Island was preserved... Entire List of Water-Birds Observed. [March 26-April 4; May 11-June 9]. The party [of the second trip] consisted of Joseph Grinnell, who had immediate charge of the expedition, and gave special attention to the ornithology and entomology of the islands; Horace Gaylord, who collected mammals; and Harry Gaylord and James Brittan [Britton] who devoted their time to archaeology.

SANTA CRUZ ISLAND

1886 Santa Cruz Island: Eli Whitney Blake, Jr. visited Santa Cruz Island twice in 1886: from July 4- July 24, and again August 6-September 3. During his visits, Blake camped in a canyon near Platt's Harbor. He noted:

1886 Santa Cruz Island: Larus occidentalis. WESTERN GULL. — Extremely abundant; nests on the isolated rocks along shore. Found many young.


1907 Santa Cruz Island: “Larus occidentalis. Western Gull. Very common.” [“At 11:30 p. m., November 19, 1907, my father (H. Linton), Mr. George Willett, and myself left San Pedro harbor in a dilapidated fishing smack and in company with a crawfisherman, one “Cold-foot” Jorgensen. We arrived off the south end of Santa Cruz Island at 10:30 the following day during a stiff norwester. For various reasons we were unable to make camp until the 22nd. It may not be amiss to state here that twice during the blow we were nearly wrecked: once while at anchor in Potatoe Harbor, a broken anchor allowing the boat to drift within the breaker line and nearly onto the rocks. In this instance the timely arrival of Willett and H. Linton in a small boat, saved the day, and incidentally the fishing smack. At another time (the engine having broken down) we were blown nearly onto the rocks of Anacapa Island; but with father at the wheel and Willett and I on the “sheet” we managed to hold her off. I mention the foregoing, and the many sleepless nights spent on the rocky shores, “running” the surf several times each day (with attendant duckings), etc., merely as a warning to those who seem inclined to believe a field naturalists ’ life “strewn with roses”. (Its ’ generally strewn with cacti!)”]
Linton, C. B. Notes from Santa Cruz Island] The Condor 10(3):124-129, May 1908

ISLA SAN MARTIN

1913 Isla San Martin: “Larus occidentalis. Western Gull. Very numerous. They seem to breed early here in order to be through with their family duties by “cormorant season”, as we found very few small young. Whenever we went anywhere about the island a large band of these white pirates followed us. They were very tame and would swoop down to destroy eggs and eat young before our very faces. I was disgusted, once, in seeing a gull carry a struggling young cormorant off by the neck. The youngster weighed about half a pound, but the gull swallowed him whole in mid-air. The last I saw of the gull, the cormorant was still kicking, in the gull’s throat. Another gull flew down near us and leisurely gobbled up a brood of four young cormorants. The rest of the youngsters showed no fear at the fate of their brothers and sisters but sat quietly and awaited their turn. I placed a camera, with a string attached to the shutter, on a rack near a nest of young cormorants, hoping to get a picture of a gull eating the young, but I was disappointed, as the old cormorant returned first.” Wright, H. W. The Birds of San Martin Island, Lower California The Condor 15(6):207-210, November-December, 1913
