108 NORTH AMERICAN FAUNA 76 



1983, we found scolding adults on 12 June. Newly hatched to half-grown 

 nestlings were found on 26 June 1962 and 10 June 1974, and fledged 

 young were found at the end of July 1962, 30 July 1974, 15 July 1976, 

 and 25 June 1978. Birds were generally present until 22 August-Septem- 

 ber. One bird was found there on 22 September 1977. 



Yellow wagtail (Motacilla /lava). Uspm, Asr, Uftn (30 May-28 Au- 

 gust). 



Yellow wagtails migrated throughout the study area and nested 

 everywhere except the northern Kilbuck Mountains. Nesting pairs were 

 found at the Kisaralik River, Goodnews Bay, Chagvan Bay, Nanvak Bay, 

 and Cape Peirce. Wagtails were common and suspected to nest on 

 Crooked Island in 1977 (P. D. Ameson and D. B. McDonald, personal 

 communication). Birds were seen at the Kisaralik River on 16-21 June 

 1987 (B. J. McCaffery, personal communication) and 8-18 August 1985 

 (M. Brown et al., unpublished); were seen at the Kwethluk River on 

 12-13 and 17-27 July 1985 (M. Brown et al., unpublished); were seen at 

 the Eek River during 7 days on 17-28 June 1985 (M. Brown et al., 

 unpublished) and in summer (R. Baxter, unpublished); were abundant 

 along the Kanektok River in June 1977 (White and Boyce 1978); seen on 

 Round Island on 15 June 1972 (two birds; E. H. Miller, unpublished); and 

 were common at Platinum and Chagvan Bay in summer 1969 0- L. Hout, 

 personal communication). Spring migrants were at the Tuluksak River 

 (6 and 8 June 1983). Fall migrants were observ^ed inland at Kagati Lake 

 (M. J. Fry, unpublished; J. L. Hout, personal communication) and the 

 Kanektok River (M. J. Fry, unpublished), as well as coastal areas at the 

 Togiak River, Goodnews Bay, Chagvan Bay, Nanvak Bay, Cape Peirce (this 

 study), and Round Island (T. J. Eley, unpublished). 



Territorial yellow wagtails used coastal lowlands and upland areas with 

 moist dwarf shrub meadows or grass meadows (primarily Elymus arenar- 

 ius on the coast) or open valley floor formations from sea level to 450 m 

 asl. Birds foraged at the edges of all types of bodies of water. The highest 

 density was just under 18 scolding pairs per square kilometer in old tailings 

 along the Salmon River (Platinum) on 20 June 1974. Scolding birds tended 

 to be several hundred meters apart in adjacent tundra habitat. Earliest 

 arrivals at Cape Peirce were on 30 May 1970 and 1976. Bull (in Friedmann 

 1933) collected an adult male at Goodnews Bay on 15 June 1933. Adults 

 carried food by 18 June 1974 near Platinum, and independent young were 

 found there by 19 July 1974. Newly fledged young were seen at Cape Peirce 

 on 1 6 July 1981 (D. R. Herter and D. Lloyd, personal communication). Fall 

 migrants were at the Kisaralik River between 26-31 July 1979, at Good- 

 news and Chagvan bays in July 1974, at the Togiak River during 5-9 August 

 1973, and at Cape Peirce and Nanvak Bay until 16-28 August. Migrants
