driftwood and above it was primarily bare soil. The west bank 

 sloped gently to the water and was forested, with a dense 

 understory of shrubs which made viewing difficult. No midstream 

 loafing sites were present because of the high water level but 

 there were abundant loafing sites along the east bank. Distance 

 from the road was >2 00 m but a well-worn trail followed the west 

 bank and an undeveloped campground was located on the west bank 

 about 100 m upstream. 



23 August (2:00pm): A group of 8 harlequins of undetermined 

 age and sex was observed on the Boulder River (T6S R12E S12) 

 about 500 m downstream from the Alpine Lodge (Figure 3) . A short 

 time previous to this observation a small group of harlequins was 

 seen flying upstream from a point 1-2 km downstream from where 

 the group of 8 was observed. It is believed that these were two 

 observations of the same group. This group was observed for about 

 15 minutes as they slowly worked their way downstream, feeding 

 along the way by bill dipping, head dipping, tipping-up, and 

 diving. The type of feeding behavior appeared to be related to 

 water depth. Individuals of the group occasionally would walk out 

 on shore and preen for a few seconds before returning to the 

 group. Group members never were separated by more than a total of 

 15 m. The group traveled about 100 m downstream before 

 disappearing from view. Habitat : Meandering stream channel with a 

 relatively gentle current broken by a short stretch of shallow 

 riffles. Both banks sloped gently to the water and were forested. 

 Shrub cover was moderately dense on both banks. There were no
