NORTH AMERICAN FAUNA 76 



Ruby-crowned kinglet (Regtilus calendula), Csr (29 May-26 Au- 

 gust). 



Kinglets were found only in the Kilbuck Mountains. We found 

 kinglets at the Salmon and Tuluksak rivers; M. Brown et al. (unpublished) 

 found 1-5 birds per day on 25-26 July 1985 at the Kisaralik River and 

 1-15 birds per day on 23 and 26 August 1985 at the Kwethluk River. At 

 the Tuluksak River in 1983, we found 1.7 pairs per square kilometer of 

 ruby-crowned kinglets in disturbed riparian plots and 24.3 pairs per 

 square kilometer in undisturbed plots. Territorial birds primarily used 

 closed spruce forests, but a few birds foraged in valley floors and slopes 

 in all woodland and tall shrub habitats to 300 m asl. We found singing 

 birds from 31 May 1974, scolding adults from 9 June 1974, molting adults 

 carrying food on 25 July 1962, fledged young from 24 June 1974, and 

 birds still present on 19 August 1974. 



Northern wheatear (Oenanthe oenanthe). VRv. 



D. R. Herter et al. (personal communication) observed a male 

 wheatear at Cape Peirce on 18 June 1984. M. Brown et al. (unpublished) 

 found a wheatear at the Eek River on 18 June 1985. Northern wheatears 

 are common migrants north of our area at St. Lawrence Island and rare 

 migrants to the southwest in the Pribilof and Aleutian islands (Kessel and 

 Gibson 1978). 



Gray-cheeked thrush (Catharus minimus). Asr (3 June-31 Au- 

 gust). Specimen: RMS 1962/36/380. 



Nesting birds were found throughout the inland portion of the study 

 area, on the coast, atid on offshore islands. Birds nested at the Tuluksak 

 River (DNW photo), Goodnews (DNW photo), and Nanvak Bay. 

 Thrushes probably nested at the Salmon and Kisaralik rivers (this study), 

 and were "suspected" to nest at Crooked Island in 1977 (P. D. Ameson 

 and D. B. McDonald, personal communication). Birds were seen in the 

 Nyac area (common on 15 July 1980; Mindell 1983), at the Kisaralik River 

 (common in 1982, Mindell 1983; seen 16-21 June 1987, B.J. McCaffery, 

 personal communication; seen on 9 days during 10-27 August 1985, 

 M. Brown et al., unpublished), at the Kwethluk River (10 days during 

 10-26 July 1985, M. Brown et al., unpublished), at the Kanektok River 

 (abundant in June 1977; White and Boyce 1978), at the Eek River (in 

 summer, R. Baxter, personal communication; on 11 days during 

 17-29 June 1985, M. Brown et al., unpublished), at the Togiak River (one 

 in August 1973; this study), and on Round Island (one on 23 July 1974, 

 Francis H. Fay in T. J. Eley, unpublished; one heard on 27 June 1976, 

 R. Macintosh, unpublished).
