Rspm, FCsr (30 April-25 September). Specimen: UAM3135. Cormorants nested on offshore islands and migrated along the coast. We recorded low numbers of cormorants migrating past Cape Peircc in 1976. Cormorants were seen at the Walrus Islands, in Togiak Bay, and on the Togiak River. They nested on Shaiak Island (Fig. 11) and on Bird Rock near Cape Newenham (present study) and on Summit Island in June-July 1977 (Ameson 1977). They

They were common in Chagvan Bay during 23-28 July 1969 Q. L. Hout, personal communica- tion). Birds foraged in rivers, nearshore waters, and inshore waters in all areas where they were observed. Cormorants from Shaiak Island congregated on beaches in Nanvak Bay during summer and flew over- land to and from Shaiak Island daily. The number of nesting pairs on Shaiak Island varied from 125 in 1973 to 300 in 1976. Nests were clustered on low, broad ledges, on flat rocks, or on the ground, mostly on the highest parts of the island. Sixty clutches averaged ± eggs per nest (range, 3-5) on 14 June 1973-Thirteen pairs fledged ± young per nest (range, 1-3) in 1976; egg laying began about 7 June, hatching was from 2 to 10 July, and fledging was from 7-29 August 1976. At least six pairs on partially completed nests were on Bird Rock on 21 May 1973, Hout (personal communica-. Fig. 11. Double-crested cormorants and nests with eggs; Shaiak Island, 14 June 1973.
