Western Gulls are found on all eight
California Channel Islands.
Western Gull egg collected by Amelia Read
San Miguel Island, c. 1888

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.


THE SAN MIGUEL ISLAND EGG. By Marla Daily. Ancestors West, volume 39, no. 4. November 2014. 34-35. http://islapedia.com/images/f/f1/THE_SAN_MIGUEL_ISLAND_EGG.pdf


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:

Larus occidentalis. WESTERN GULL. — Extremely abundant; nests on the isolated rocks along shore. Found many young.


“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 P.O.B.S.P. (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.
