be used to conduct surveys. I found that one person could survey 

 a large area, but morale and effectiveness suffered. To 

 determine nesting and brood rearing habitat, breeding season 

 chronology, and productivity of harlequins on the Flathead 

 National Forest, more people need to be involved in the field. 

 As suggested by Wallen and Groves (1989) , an intensive study at 

 one locale would provide specific information needed for 

 management of harlequin ducks on their breeding grounds. A 

 review of the literature suggests that much is to be learned of 

 the wintering biology and habitats of harlequin ducks also.
