1897: “Phalacrocorax dilophus albociliatus—Farallone Cormorant. Immature birds were seen commonly about San Nicolas Island, but none were found breeding. On Santa Barbara Island, however, this Cormorant was breeding in large numbers. Most of the birds were nest-building, and but two sets, of three and four fresh eggs were found—May 15. Their nests were made of coarse sticks and seaweeds, and built usually on the ground on the sloping sides of the island above the rocks; several nests were built in bushes from one to three feet above the ground. The nests of this species of Cormorant were never in close colonies, but scattered promiscuously wherever the birds fancied. Single nests were frequently found by themselves a long distance from any others. One specimen of the Farallone Cormorant was saved... 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. The party left San Pedro harbor May 11 in a large fishing schooner... [returning June 9, 1897]”

1984 San Clemente Island: “DOUBLE-CRESTED CORMORANT (Phalacrocorax auritus). Fairly common year-round but no breeding records: 12 modern records from 17 Nov to 30 Jul. Linton (1908) reported a flock of 200 or more 5 Feb 1907 and listed them as fairly common. Possibly overlooked in large flocks of Brandt's Cormorants.

SANTA CRUZ ISLAND
1907 Santa Cruz Island: “Phalacrocorax dilophus albociliatus. Farallone Cormorant. Fairly 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!)”]
