32 NORTH AMERICAN FAUNA 76 



young in 1979 and 1983. D. R. Herter and D. Lloyd (unpublished) found 

 a female and three young near Nanvak Bay in 1981. 



Northern pintail (Anas acuta), Aspm, Csr, Afin (23 April-10 October). 



Pintails nested throughout the study area and migrated along the 

 coast. We found pintails migrating past Cape Peirce during 27 April- 

 19 May 1973 (peak, 4 May) and 28 April-17 May 1976 (peak, 2 May). 

 C. P. Dau (unpublished) reported 15 birds between Platinum and Secu- 

 rity Cove during an aerial survey on 23 April 1981; D. F. Parmelee and 

 J. M. Parmelee (unpublished) observed one to seven birds occasionally 

 at Chagvan Bay from 20 to 24 May 1987. Birds used areas flooded by 

 meltwater near Nanvak Bay in spring (MRP photo). The sex ratio of 347 

 birds in mixed flocks seen at Nanvak Bay between 1 and 17 May 1973 

 was 2.6 males to 1.0 female. One pair was in the marsh at Cape Peirce 

 on 28 June 1970 (H. P. Brokaw, unpublished). The first fall migrants 

 (males) appeared at Cape Peirce on 28 July 1970 and 8 August 1976, and 

 pintails were seen throughout fall. There were several thousand at 

 Nanvak Bay on 27 August 1970, and roughly 800 birds there on 22 

 September 1973. We found migrants at Goodnews and Chagvan bays on 

 12-15 September 1977, and J. L. Hout (personal communication) found 

 pintails in Nanvak Bay on 25 September- 1 October 1971. Estimates of 

 pintails during late fall surveys of the entire coastal area included 6,803 

 in 1980 (6 October; R. Gill, Jr., and R. King, unpublished), 385 in 1982 

 (6 October; R. J. King and K. S. Bollinger, unpublished), 665 in 1985 

 (10 October; R.J. King and W. D. Eldridge, unpublished), 1,956 in 1987 

 (2 October; R. J. King and W. D. Eldridge, unpublished), 2,804 in 1988 

 and 217 in 1989 (8 and 7 October, respectively; R. J. King and L. 

 Denlinger, unpublished). 



We found birds nesting at the Salmon River, the Tuluksak River, the 

 Kisaralik River, Goodnews Bay, Chagvan Bay, and Nanvak Bay; J. G. King 

 (unpublished) reported a female on six eggs at Nanvak Bay on 3 July 1963, 

 and D. R. Herter and D. Lloyd (personal communication) found a female 

 with four ducklings on 3 July 1981. Pintails nested at Kagati Lake (M. J. 

 Fry, unpublished) and probably nested along the Kanektok River (White 

 and Boyce 1978); M. Brown et al. (unpublished) found birds at the Eek 

 River on 17-24 June 1985; P. D. Ameson and D. B. McDonald (personal 

 communication) found nesting birds at Crooked Island in June 1977. At 

 the Tuluksak and Kisaralik rivers, we found 12 females with 1 to 9 young 

 Qx = 4.5 young per brood) and 4 newly fledged broods on 24 July- 13 

 August. Mindell (1983) considered them uncommon near Nyac. B. J. 

 McCaffery (personal communication) found them at the Kisaralik River 

 on 17 June 1987. Flightless adults were in Chagvan Bay on 21-29 July 

 1969 Q. L. Hout, personal communication). We found pintails in Nanvak
