 range extension reported in American Ornithologists' Union (1983). 



Pelagic cormorant (PfuUacrocorax pelagicus). Aspm, Asr (18 April- 

 27 September). Specimens: UAM2622, UAM2623, and YDNWR (no acces- 

 sion number). 



Cormorants were found along the coast and in estuaries. They mi- 

 grated past Cape Peirce in spring (peak migration rate of 260 birds per 

 hour on 2 May 1973) and may migrate along the coast in late fall. J. G. King 

 (unpublished) saw more than 10,000 pelagic cormorants near Hagemeis- 

 ter Island on 30 April 1974. Generally, migration along the coast occurred 

 from 28 April to 1 June; however, D. I. Eisenhauer (personal communica- 

 tion) found birds in Chagvan Bay on 18 April 1973. Birds nested on all 

 suitable coastal cliffs (Fig. 12) from the Beluga Peaks in Goodnews Bay to 

 the Walrus Islands. The following are breeding population estimates (from 

 Sowls et al. [1978] except as noted): Big Beluga, 420 pairs (DNW photo); 

 Little Beluga, 30 pairs (DNW photo); Cape Peirce, 350 pairs (nest, eggs, 

 MHD photo; nest, young, MRP photo); Shaiak Island, 50 pairs (MHD 

 photo; MRP photo); Hagemeister Island, 345 pairs; Walrus Islands, 9,780
