INTRODUCTION 



The harlecniin duck. (Hi strionicus histr ionicus ) is a Forest Service 

 Sensitive Species on the Kootenai National Forest. The occurrence 

 of this species of sea duck is rare to uncommon on the forest. 

 Documented harlequin reproduction has occurred on the Cabinet 

 Ranger District, eind nesting is suspected to occur on the Three 

 Rivers Ranger District, Libby Ranger District, and Fortine Ranger 

 District. Verified sitings of harleguin ducks on the KNF (excluding 

 the Cabinet R.D.) during the 1980's include:
