1 1 2 NORTH AMERICAN FAUNA 76 



Tuluksak River in 1983, we found at least two singing males in riparian 

 broadleaf tree habitat and found three males in 0. 1 km2 of riparian tall 

 shrub thicket above timberline. Singing males were present at Kisaralik 

 Lake (450 m asl) in July 1979. Yellow warblers were seen in summer at 

 the Kisaralik River in 1982 (Mindell 1983), in 1985 (6 days during 

 10-20 August; M. Brown et al., unpublished), and in 1987 (17 June; B. J. 

 McCaffery, personal communication). Warblers were also found at the 

 Kwethluk River (5 days during 1 1-26 July 1985; M. Brown et al., unpub- 

 lished), the Eek River (R. Baxter, unpublished), Kagati Lake (27 July 1962; 

 M. J. Fry, unpublished), the Kanektok River (common in June 1977; 

 White and Boyce 1978), Round Island in 1972 (4 days during 12-18June; 

 E. H. Miller, unpublished) and 1976 (27 June; R. Macintosh, unpub- 

 lished), and Crooked and Hagemeister islands ("suspected" nesting in 

 June-July 1977; P. D. Ameson and D. B. McDonald, personal communi- 

 cation). We found singing males at Platinum on 20 June 1974, south of 

 Slug Mountain on 11 June 1973, and at the Slug River on 28 June 1970. 

 We saw birds at the Togiak River on 5 and 8 August 1973- D. R. Herter 

 et al. (personal communication) saw birds at Cape Peirce on l6 and 28 

 June and 9 and 15 July 1984. 



Yellow-nimped warbler (Dendroica coronatd). FCsr (19 May-24 

 August). Specimen: RMS 1962/36/47. 



This warbler nested in the Kilbuck Mountains and was seen else- 

 where. Birds nested each year at the Salmon and Tuluksak rivers and 

 possibly nested at the lower Kisaralik River; warblers were seen at the 

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

 tion) and 28 August 1985 (M. Brown et al., unpublished). One male D. c. 

 coronata was seen on 19 May 1976 at Cape Peirce. One bird was also 

 seen at Cape Peirce on 12 June 1984 (D. R. Herter et al., personal 

 communication). At other sites, birds were seen at the Kwethluk River 

 (4 days during 17-26 July 1985; M. Brown et al., unpublished), at the Eek 

 River (summer; R. Baxter, unpublished), and at the Kanektok River (two 

 singing males in June 1977; White and Boyce 1978). We found 3 3 pairs 

 per square kilometer in disturbed and 22.9 pairs per square kilometer 

 undisturbed riparian plots (mainly spruce-poplar) at the Tuluksak River 

 in 1983. 



Territorial birds used tall shrub thickets in riparian habitat 75-300 m 

 asl. At the Tuluksak River, we first found warblers on 3 June 1983, saw 

 adults carrying food beginning 24 June 1974, and found young fledging 

 on 1 July 1974. Family groups were common to 28 July 1974; single birds 

 were in feeding flocks with other passerines from 7 August 1974. Birds 

 in basic plumage were seen on 4 August 1962, 24 August 1974, and 

 19 August 1977.
