this survey. Streams in the Bob Marshall Wilderness should be 

 evaluated as potential harlequin habitat and searched as deemed 

 suitable. Pat Clancy MDFW&P (pers. comm.) observed 2 female 

 harlequins fly past him in 1979 near the confluence of Dolly 

 Varden and Argosy Creeks in the Bob Marshal Wilderness. 



Swan Lake Ranger District 



No harlequin ducks were observed on creeks surveyed on the 

 Swan Lake Ranger District. There are no known historic records 

 of harlequin ducks on any creeks in the Swan River Drainage 

 despite extensive fisheries research done on the creeks in the 

 district and no observations were reported to me during this 

 survey. No extensive surveys were conducted although stream 

 measurements were taken on 5 creeks in the drainage and small 

 reaches of stream were surveyed. Most of the creeks in this 

 district appeared to be small and have extensive swampy areas. 

 This district should be surveyed further especially stretches of 

 the Swan River near Condon. 



CONCLUSIONS AND RECOMMENDATIONS 



This survey suggests that harlequin ducks are uncommon and 

 localized breeders on the Flathead National Forest. Wallen and 

 Groves (1989) found harlequins in northern Idaho to be localized 

 and uncommon breeders, and both breeding and wintering numbers
