Santa Barbara (cont'd) day and night. One was seen carrying what appeared to be a large insect. Zonstichia leucophrys (8) White-crowned Sparrow Passerculus sandwichensis (1) Savannah Sparrow Melospiza lincolnii (2) Lincoln's Sparrow MAMMALS Mouse holes and runs were plentiful on the island. Church saw one unidentified mouse in one of the quonset huts. Brownell collected one unidentified rodent skull and Kleen saw one rabbit, also in the quonset hut. Calophus californianus (1,000+) California Sealion This species was observed hauled out on three different localities. Some 320 animals were noted on the beach south of the landing. Over 200 were hauled out below the steep cliffs on the southwest side across from Sutil Island. Over 100 sealions occupied the northwestern point. Three dead Zalophus were noted on the beach south of the landing and one dead female (total body length ca. 250 in.) was found on the northwest point. The total populations of the species must be well over 1,000 animals. Anacapa April 5, 1968 Anacapa has three main islands, East, Middle, and West with several rock islets off each. Kleen and Church made the land survey. With the exception of a colony of Brown Pelicans, few marine birds appeared to be using West Island where we landed. It was impossible to reach the sloping areas of the north side of the island because they terminated in cliffs which could not be climbed. The South side of the island was unscalable and the only bird observations made were from the rocky shore which extended its full length. Banks (1966) must have been able to get ashore further west than our landing as he mentions tree-filled arroyos. None of these was seen. The ground in places was fairly damp, indicating recent precipitation. The giant coreopsis, (Coreopsis maritima) was in full bloom as were succulents, a plant which resembles Indian Paint Brush, a lavendar-colored flower of the daisy family, and a yellow-flowered low-growing dense ground cover. Abalone shells were common on the beaches. While Church and Kleen were on the island the ship cruised offshore. Brownell saw 750 - 1000 Surf Scotors. Bird Species Pelecanus occidentalis (200+) Brown Pelican This was the only species which appeared to be nesting. Unfortunately, we were unable either to reach the colony or to see it well enough to make a positive count of nests. Church thought she saw downy young. The colony is in two sections, one above and east of the other. The upper segment
