Red-legged kittiwake (Rissa brevirostris), VRv. 



We saw this species twice in 1976. On 30 April, four adults rcx)sted 

 on some ice in Nanvak Bay, and on 2 September, a hatching-year bird 

 roosted on some rocks at Cape Peirce. Ameson (1977) saw one bird 

 roosting on the beach rocks at High Island on 11 July 1977. Gabrielson 

 and Lincoln (1959) reported that "a number circled about the boat as it 

 passed Cape Newenham on July 12" 1946. 



Sabine's gull (Xema sabint), Rv, Rsr? 



Sabine's gulls occurred at coastal locations on the study area. We 

 found Sabine's gulls on South Spit at Goodnews Bay on 13 and 19 June 

 1974 and 1 6 July 1986 and at Nanvak Bay during 5 days between 12 and 

 31 May 1976. J. G. King (unpublished) saw a few birds at Nanvak Bay on 

 5 July 1974. Three birds were seen swimming in Chagvan Bay on 27 May 

 1987 (D. F. Parmelee and J. M. Parmelee, unpublished). B. Huffinon 

 (personal communication) reported them nesting at Ilanik Lakes, although 

 we found none nesting there in June 1974. 



Arctic tern (Sterna paradisaea), Asr (12 May- 15 September). Speci- 

 men: RMSI962/36/23. 



Arctic terns nested in suitable habitats on the coast and inland, and 

 foraged in streams, lakes, estuaries, and inshore waters. Terns nested at
