KILBUCK AND AHKLUN MOUNTAIN BIRDS 1 1 1 



young to 22-25 August and adults to 14 October. Fledged young were at 

 the Kisaralik River on 27 and 30 July 1979. 



Orange-crowned warbler (yermiv€n'a celatd), FCsr (31 May-31 

 August). Specimens: UAM2643, RMS 1962/36/43, RMS 1962/36/44, and 

 BMNH/83sk/DNW03. 



Orange-crowned warblers nested throughout the study area. Birds 

 nested each year at the Tuluksak River 0)NW photo) and some years at 

 Cape Peirce, and probably nested each year at the Salmon and Kisaralik 

 rivers and at Chagvan and Goodnews bays; warblers were seen at the 

 Kisaralik River (16-21 June 1987, B. J. McCaffery, personal communica- 

 tion; 6 days during 10-20 August 1985, M. Brown et al., unpublished), at 

 the Kwethluk River (11 days during 10-27 July 1985, M. Brown et al., 

 unpublished); and at the Eek River (9 days during 17-29 June 1985; 

 M. Brown et al., unpublished). Warblers were common and "suspected" 

 to nest on Crooked Island in 1977 (P. D. Ameson and D. B. McDonald, 

 personal communication). 



Pairs and nests were 15-150 m asl in shrub thickets on the coast or 

 riparian woodlands with willows in valley floors in inland areas. One nest 

 at the Tuluksak River was in an open riparian white spruce forest in a 

 cavity at the base of a willow. We found 17 pairs per square kilometer in 

 disturbed and undisturbed riparian plots at the Tuluksak River in 1983. 

 Birds were present on our arrival at the Tuluksak River on 3 1 May-2 June 

 during all years. One bird incubated five eggs there on 22 June 1974, and 

 young fledged between 7 and 14 July in all years. Some birds were still 

 feeding nestlings between l6 and 20 July in all years, and birds were 

 present on 22-23 August 1974 and 1977. Along the coast near Cape 

 Peirce, birds used dense willows at the Slug River on 10 June 1973 and 

 28 June 1970, and at Slug Mountain on 10 June 1973- Fledglings chased 

 adults on 28 July 1970, and one bird was present at Security Cove on 

 31 August 1973. No birds were seen near Cape Peirce in 1976. D. R. 

 Herter et al. (personal communication) found them at Cape Peirce on 

 28 June and 15 July 1984. 



Yellow warbler (Dendroica petechia), Rsr?, Rfm. Specimens: 

 RMS1974/1 19/06, and BMNH/83sk/DNW12. 



This species occurred irregularly throughout the study area. We 

 found no nests, but recorded singing males in summer at most locations. 

 Birds were seen at the Salmon River only on 8 August 1977. At the 

 Tuluksak River (dead adult; DNW photo), we found territorial birds in 

 1979 (4-14 July), 1980, and 1981. We saw one bird there on 18 August 

 1977 and none there in 1962, 1974, 1976, and 1987. MindeU (1983) 

 considered them uncommon in the Nyac area on 15 July 1980. At the
