October 1979, and January, April, June and August 1980, following the 

 instructions outlined in the baseline report (DNRC 1979, Appendix F) . 



Bald Eagle Survey 



The Kootenai River between Libby and Troy was surveyed for bald eagles on 

 January 16 (2 counts) and January 17 (,1 count), following the methods of 

 Meyer (1979). Surveys were made from U.S. Highway 2. Bald eagles seen 

 during general surveys and riparian habitat censuses were also recorded. 



Harlequin Duck Special St udies 



In addition to surveys made during riparian habitat censuses, special 

 searches of the Kootenai Falls area for harlequin ducks were conducted each 

 study day in June and August. In June, emphasis was placed on determining 

 the total harlequin duck population and the number of pairs present in the 

 project area; in August, emphasis was placed on locating broods. 



Bighorn Sheep Survey 



One day per visit, the cliffs north of the river between Libby and Troy 

 were surveyed with a spotting scope from strategic viewpoints along U.S. 

 Highway 2. All observations were recorded on field maps and data sheets. 



On April 10 and 11, ground searches for evidence of sheep use were 

 conducted on the north shore of the Kootenai River adjacent to known bighorn 

 sheep range. These data also were recorded. Differentiating between deer 

 and bighorn sheep sign was difficult.
