KILBUCK AND AHKLUN MOUNTAIN BIRDS 



113 



Blackpoll warbler (Dendroica striata}' FCsr (3 June-3 1 August). 

 Specimens: RMS 1962/36/48, BMNH/83sk/DNW05, 

 BMNH/83sk/DNW09, and BMNH/83sk/DNWll. 



Blackpoll warblers were found in the Kilbuck and Ahklun mountains 

 and twice on the coast. Warblers nested at the Tuluksak River and 

 probably nested at the Salmon and Kisaralik rivers. Mindell (1983) found 

 them an uncommon nesting bird on 15 July 1980 near Nyac. Warblers 

 were seen at the Kisaralik River (16-21 June 1987; B. J. McCaffery, 

 personal communication), at the Kwethluk River (10 days during 10-27 

 July 1985; M. Brown et al., unpublished, and at the Eek River (7 days 

 during 21-29 June 1985; M. Brown et al., unpublished). Two birds were 

 seen at the Kanektok River in June 1977 (White and Boyce 1978). We 

 saw a blackpoll warbler once along the coast at Security Cove (one male 

 on 31 August 1973). An adult female was collected on 2 June 1990 at 

 Cape Peirce (K. Winker and J. Klicka, unpublished). 



Territorial birds in the Kilbuck Mountains used open valley floors in 

 tall shrub thickets and spruce forests with dense shrub understory. At the 

 Tuluksak River in 1983, we found 4 5 0 pairs per square kilometer in 

 disturbed and 28.6 pairs per square kilometer in undisturbed riparian 

 plots. Adults there carried food from 24 June 1974, fledged young were 

 seen 12 through mid-July 1962, and birds were present until 23 August 

 1977. Adult males were molting by 18 July 1979, and some females were 

 in basic plumage by 25 July 1962. 



Northern waterthnish (Seiurus noveboracensis). Asr (11 June- 

 25 August). Specimen: RMS 1962/36/4 5. 



Waterthrushes nested throughout the Kilbuck Mountains, possibly 

 nested in the Ahklun Mountains, and were seen on the coast. Birds 

 nested each year at the Tuluksak River, probably nested at the Salmon 

 and Kisaralik rivers, and were seen along the coast south of Slug 

 Mountain (one on 11 June 1973), and at Togiak Lake and the Togiak 

 River (3 and 10 August 1973). Birds have been seen in the Nyac area on 

 15 July 1980 (common; Mindell 1983); along the Kisaralik River in 1982 

 (common; Mindell 1983), 1985 (9-10 and 20 August; M. Brown et al., 

 unpublished), and 1987 (20-21 June; B. J. McCaffery, personal commu- 

 nication); at the Kwethluk River (12 days during 10-27 July 1985; M. 

 Brown et al., unpublished); at the Eek River (in summer [R. Baxter, 

 unpublished] 6 days during 19-21 June 1985 [M. Brown et al., unpub- 

 lished]); and along the Kanektok River (one heard; White and Boyce 

 1978). Bull (in Friedmann 1933) collected one adult female on 1 1 June 

 1933 near Goodnews Bay. 



Territorial waterthrushes used all riparian woodlands and shrub 

 habitats (except black spruce) 60-300 m asl and occasionally used damp
