pairs; Summit Island, 530 pairs; and at Nunavachak Lake, about 300 pairs 

 (present study). 



At Cape Peirce, pairs had arrived at nest sites by late April 1973 and 

 1976. Birds laid eggs from mid-May to early July, hatched young in 

 mid-June to late July, and the young fledged from early August to early 

 September (Table 2). J. G. King (unpublished) found nests with eggs on 



3 July 1964. Numbers of pelagic cormorants in the area declined gradually 

 in fall, and by 25 September 1973 only 1 1 birds remained at Cape Peirce. 



Red-faced cormorant (Phalacrocorax urile), Rsr. Specimen: 

 UAM3136. 



This cormorant nested on the coast in some years. We found 2 pairs 

 at Big Beluga in 1974 (DNW photo) and 1-7 pairs at Cape Peirce between 



4 May and 1 September 1970-76, about a dozen pairs nested on the cliffs 

 at Cape Peirce 25-29 June 1970 (H. P. Brokaw, unpublished), and Sowls 

 et al. (1978) reported 21 pairs at Hagemeister Island in 1977. We found 

 fewer than 100 pairs on Round Island in 1962; however, none were found 

 there in 1974 (T. J. Eley, unpublished), 1976 (R. Macintosh, unpub- 

 lished), or 1977 (Ameson 1977). Because they nested among pelagic 

 cormorants, numbers of red-faced cormorants may have been underesti- 

 mated. This information documents red-faced cormorant nesting in the 

 region as reported in Kessel and Gibson (1978). 



Frigatebird (Fregata sp.). VRv. 



Petersen saw a bird with immature plumage at Cape Peirce on 20 

 May 1976. The frigatebird was flying and gliding along the dunes and 

 clifis, then west out to sea. This bird was far out of its normal range and 

 further north along the Pacific coast than frigatebirds have previously 

 been recorded. Magnificent frigatebirds (F. magnificens) have been 

 reported on the Pacific coast to south-coastal Alaska, although it usually 

 ranges from northern California to northern Peru when along the Pacific 

 coast (American Ornithologists' Union 1983). Neither of the other two 

 species have been reported along the Pacific coast. 



Tundra swan (Cygntis columhianus). Uspm, Usr, Cfm (23 April-7 

 October). 



Swans migrated along the coast and nested on the coastal plain. We 

 found swans in ice-free ponds during spring migration near Nanvak, 

 Goodnews, and Chagvan bays. Swans migrated past Cape Peirce in 

 spring; they were seen between Platinum and Cape Peirce on 23 April 

 1981 (C. P. Dau, unpublished). Swans were seen near Nyac (Mindell 

 1983), at the Kisaralik River (17-18 and 28 August 1985; M. Brown et al., 

 unpublished), at the Kwethluk River (10 and 18 July 1985; M. Brown
