KILBUCK AND AHKLUN MOUNTAIN BIRDS 63 



news Bay between 23 and 29 July 1969. We collected an adult female 

 black tumstone, probably nesting, at the confluence of the Tuluksak and 

 Kuskokwim rivers just outside our study area on 16-17 June 1962. 



Surfbird (Aphriza virgatd). Uspm, FCsr (19 May- 12 August). Speci- 

 mens: RMSI962/36/O8 and RMSI962/36/O9. 



Surfbirds nest in northern and probably in southern parts of the study 

 area and migrate along the coast. Birds were found along the rocky coast 

 at Cape Peirce in 4 of 6 years: during 3 days between 18 and 28 June 1976 

 (this study), 2 days between 27 and 30 July 1981 (D. R. Herter and D. 

 Lloyd, personal communication), 8 June and 18 July 1984 (D. R. Herter 

 ct al., personal communication), and 8 days between 15 May and 9 Au- 

 gust 1990 (K. Winker and J. Klicka, unpublished). A single and three birds 

 were observed among rock sandpipers (Calidris ptilocnemis) at Chagvan 

 Bay on 26 and 27 May 1987, respectively (D. F. Parmelee and J. M. 

 Parmelee, unpublished). One male surfbird was collected by Bull (in 

 Friedmann 1934) at Goodnews Bay on 12 August 1933. P. D. Ameson 

 and D. B. McDonald (personal communication) saw a surfbird at Crooked 

 Island on 5 July 1977. Birds nested at the Tuluksak River (this study) and 

 at the Salmon River (J. Bloomquist, personal communication), and were 

 seen at the Kisaralik River on 20 June 1987 (B. J. McCaffery, personal 

 communication) and the Eek River on 18 and 28 June 1985 (M. Brown 

 et al., unpublished). We flushed pairs from appropriate nesting habitat 

 at Tokomarik Mountain near Cape Newenham on 19 May 1973; an adult 

 female with an egg in the oviduct was collected on 22 May 1990 at Cape 

 Peirce (K. Winker and J. Klicka, unpublished). 



At the Tuluksak River, calling adults or chicks were found or re- 

 ported at two locations in 1 96 1, up to five in 1962, two in 1974, zero in 

 1976-79, and one each in 1981 and 1983. All sites were 6OO-9OO m asl 

 on ridges or plateaus 90-350 m wide and in dry dwarf shrub meadows, 

 block-fields, and screes. An incubating adult was found on 4 June 1974 

 and a small downy chick found on 26 June 1962. Adults performed 

 distraction displays on 4 July 1981 and 4 July 1983, and an almost fully 

 feathered chick was found on 2 August 1962. Remains of an adult were 

 found in pluckings near a gyrfalcon nest on 9 July 1987. Adults had 

 apparently left the Tuluksak River area by 2 August I962. 



Red knot (Ciilidris canutus), VRfm. 



In 1981, D. R. Herter and D. Lloyd (personal communication) found 

 two knots at Nanvak Bay on 8 August and one on 10 August. J. L. Hout 

 (personal communication) found flocks of five to six birds at Chagvan 

 Bay between 23 and 28 July 1969.
