NORTH AMERICAN FAUNA 76 



duckling was at the Salmon River on 29 July 1986. A brood of partly 

 downy young was at the Togiak River on 6 August 1973. During aerial 

 surveys of the coastal area, 25 and 130 wigeons were counted on 

 8 October 1988 and 7 October 1989, respectively (R. J. King and L. Den- 

 linger, unpublished). 



Redhead (Aythya americand), VRv. 



A single redhead was seen at Cape Peirce on 25, 27, and 28 June 

 1984 (D. R. Herter et al., personal communication). Redheads have been 

 reported occasionally in western and southwestern Alaska (Kessel and 

 Gibson 1978). 



Greater scaup (Aythya marila), Aspm, Usr, Rfm (23 April- 23 Sep- 

 tember). 



Scaup migrated and nested along the coast, probably nested in the 

 Kilbuck and Ahklun mountains, and molted in the Ahklun Mountains. We 

 frequently found several hundred spring migrants at Nanvak Bay during 

 spring migration (28 April- 10 June 1973 peak, 15 May; 30 April-31 May 

 1976 peak, 10 May). C. P. Dau (unpublished) reported 6 scaup from 

 Platinum to Security Cove during an aerial survey on 23 April 1981 and 

 47, 407, 2, and 12 between Carter Spit and Platinum on 25 April 1983, 

 28 April 1984, 12 May 1985, and 4 May 1986, respectively. D. F. Parmelee 

 and J. M. Parmelee (unpublished) identified six male and two female 

 greater scaup in Chagvan Bay on 27 May 1987. During aerial surveys along 

 the coast, estimates of scaup included 1,042 in 1982 (2 May; R. J. King 

 and C. P. Dau, unpublished), 690 in 1988 (3 May; R.J. King and C. P. Dau, 

 unpublished), and 1,019 in 1989 (4 May; R. J. King and C. P. Dau, 

 unpublished). We saw two pairs each year during summer at the Tuluksak 

 River in two upland lakes and believed they nested there. Birds were also 

 seen during summer at the Kisaralik River on l6 June 1987 (B. J. 

 McCaffery, personal communication), Kagati Lake in July 1962 (M.J. Fry, 

 unpublished), and the Eek River on 17-25 June 1985 (M. Brown et al., 

 unpublished); 25 were molting near Kagati Lake on 3 August 1973 Q- L. 

 Hout, personal communication). We suspect that they also nested at 

 Goodnews and Chagvan bays; J. L. Hout (unpublished) found 40-50 

 scaup in Chagvan Bay on 23-28 July 1969. D. R. Herter and D. Lloyd 

 (personal communication) observed adult scaup with broods in Nanvak 

 Bay on 3 August 1981, and D. R. Herter et al. (personal communication) 

 found birds there on 7-29 June and 18 July 1984. We found fall migrants 

 at Nanvak Bay on 1 September 1973 and 1 at the Tuluksak River as late 

 as 23 September 1977; J. G. King (unpublished) found 5,000 birds in 

 September 1963 at Chagvan Bay.
