survey and a summer brooding survey. Our objectives of spring 

 surveys were to: 



1. locate harlequin ducks. 



2. determine staging areas. 



3. estimate arrival times. 



4. identify streams to include in summer brood surveys. 



We conducted spring surveys by walking or driving along streams 

 or bodies of water searching for harlequin ducks and subjectively 

 assessing the habitat. We were not able to walk in the streams 

 due to the unsafe conditions created by spring runoff. 



We conducted our summer brood surveys in a similar fashion 

 to spring surveys, additionally taking advantage of opportunities 

 to walk or canoe streams. We preferred to walk upstream when 

 possible as this proved to be more effective at locating and 

 observing harlequin ducks. Our objectives of summer brood 

 surveys were to: 



1. determine occurrence and distribution of harlequin ducks 

 and broods. 



2. describe occupied and unoccupied habitat. 



For both surveys we completed a Natural Heritage Animal Survey 

 Form (Appendix A) . 



To characterize and describe stream and harlequin duck 

 habitat we assessed particular components of the area surveyed: 



1. type of stream channel. 



2. stream side vegetation. 



3. presence and type of loafing areas, hiding cover, and
