Semipalmated plover (Charadrius semipatmatus), Asr, U£m 

 (5 May- 17 September). Specimen: WFB862. 



This plover was found throughout the study area. Birds nested at the 

 Salmon River, the Tuluksak River G^NW photo), Kisaralik Lake and the 

 Kisaralik River, Goodnews Bay (DNW photo), Chagvan Bay, Nanvak Bay 

 (MHD photo), and Cape Peirce, and possibly the Togiak River and Togiak 

 Lake. Birds were also found in summer at the Eek River (R. Baxter, 

 unpubli^ed; M. Brown et al., unpublished), nested at Kagati Lake (M. J. 

 Fry, unpublished), and were found at Kanektok River (White and Boyce 

 1978; J. L. Hout, personal communication) and the Kwethluk River 

 (M. Brown et al., unpublished). P. D. Ameson and D. B. McDonald 

 (personal communication) foimd nesting birds at Crooked Island Qune- 

 July 1977) and suspected that nesting occurred at Summit, High, and 

 Hagemeister islands. D. F. Parmelee and J. M. Parmelee (unpublished) 

 found nesting birds near Chagvan Bay in 1987. 



Nests and birds performing territorial displays were on beaches, bare 

 lake and river shores and bars, coastal and inland block-fields, airstrips, 

 roads, and mine tailings to 450 m asl. B. J. McCaffery (personal commu- 

 nication) found a bird performing nest distraction displays at the Kisaralik 

 River on 1 6 June 1987. M. J. Fry (unpublished) found 50-90 pairs nesting 

 around Kagati Lake in 1962. At Cape Peirce and Nanvak Bay, eggs were 

 laid beginning in late May; one clutch was completed on 24-25 May 1970, 

 one nest had four eggs hatch on 18 June 1970, and one pair was still 

 incubating on 23 June 1973. D. R. Herter and D. Lloyd (personal commu- 

 nication) found single broods with one chick each on 1 0 and 1 2 July 1981, 

 and D. R. Herter et al. (personal communication) found single broods of 

 two chicks on 25 and 28 June 1984 at Nanvak Bay. Young were seen at 

 the Tuluksak River beginning on 26 June 1962 and 8 July 1973- In 1987, 

 a nest near Chagvan Bay contained one egg on 24 May, two eggs on 

 26 May, and three eggs on 27 May (D. F. Parmelee and J. M. Parmelee, 

 unpublished). We found eggs hatching beginning on 18 June 1974 in the 

 Goodnews-Chagvan Bay area, where five pairs had young in ages varying 

 from small downy to recently fledged and fledged on 17-20 July 1974. 

 Birds generally left their nesting areas between 26 July and 10 August. 

 We found fall migrants at Nanvak Bay until 17 September 1973. 



Black oystercatrher (Haematopus bachmant). VRsr. 



Eley (1976) found a pair of oystercatchers with two small young on 

 Round Island on 15-21 July 1974. We saw none there in 1962, and none 

 were recorded elsewhere on the study area.
