NORTH AMERICAN FAUNA 76 



birds there on 7 July 1984. J. L. Hout (personal communication) found 

 10-20 birds in Chagvan Bay on 23-28 July 1969. R. J. King and L. Denlinger 

 (unpublished) found 20 birds on 8 October 1988 and 7 October 1989 

 during aerial surv^eys along the coast. 



We found red-breasted merganser broods in streams >5 m wide and 

 in lakes from sea level to about 400 m asl. Up to 10 adults and from 2 to 5 

 broods (DNW photo; 7.2 ± 1 . 14 pairs or broods per year) were seen at the 

 Tuluksak River (48 km of streams) in 8 of 10 years; in 1986 we found no 

 broods. From the air at the Kisaralik River, we saw no broods in 1977, 1 

 in 1978, and 20 in 1979. During a float trip on the Kisaralik River in July 

 1979, about 100 birds per day were seen, with flocks of up to 40 birds. 

 Pairs and singles were seen most days during a float trip on the Kisaralik 

 River on 16-21 June 1987 (B. J. McCaffery, personal communication). 

 During a float trip on the Salmon River in August 1979 about 200 birds 

 per day were seen (maximum about 500 birds per day), with flocks of up 

 to 60 birds. Broods of 8 and 15 ducklings were seen from 4 to 6 August 



1973 during a float trip on the Togiak River. In inland areas, 12 broods 

 averaged 7.5 young (range, 1-15). At the Tuluksak River, small downies 

 were found on 28 June 1974, broods fledged beginning 11 August 1977 

 and 22 August 1974, and no birds were seen after 20 September. We found 

 downy young in Nanvak Bay on 15 August- 5 September, and D. R. Herter 

 and D. Lloyd (personal communication) found 1 female with 14 downy 

 young on 17 July 1981 at Cape Peirce. 



Osprey (Pandion haliaetus), VRsr. 



We recorded single ospreys on three occasions in spring— at Cape 

 Peirce on 20 May 1 976 and 5 June 1970 and at Slug Mountain (Cape Peirce) 

 on 10 June 1973. Ospreys may have nested at the upper Salmon River in 



1974 and did nest downstream of our study area on the lower Salmon and 

 Aniak rivers in 1979 and 1986. They also nested at the Kanektok River in 

 1962. One was seen at the Tuluskak River in August 1952 and one adult 

 was seen on the lower Kisaralik River on 30 July 1979. 



Bald eagle (Haliaeetus leucocephalus), Usr, Ufm (23 April-15 Octo- 

 ber). 



Bald eagles nested throughout the study area and migrated through 

 the Kilbuck Mountains. Eagles nested at the Salmon River (DNW photo), 

 the Kisaralik River (this study, B. J. McCaffery and R. D. Ernest, unpub- 

 lished), the Kanektok River (White and Boyce 1978; J. L. Hout, personal 

 communication), Goodnews Lake, the Goodnews River (this study), 

 Cape Newenham (J. L. Hout, personal communication). Cape Peirce 

 (MHD photo; MRP photo; D. R. Herter and D. Lloyd, personal commu- 

 nication). Round Island (E. H. Miller, unpublished), and Crooked Island
