The double-crested cormorant and Lewis' woodpecker are 

 listed as species of high federal Interest. Double-crested 

 cormorants were visitors along the Tongue River from the 

 rookery on the Tongue River Reservoir. Lewis* woodpeckers 

 were observed frequently along the county road on Leaf 

 Rock Creek. 



Nongame Mammals 



Twenty species of mammals. Including game species were observed 

 on the Klrby study area (Table 135). This list Is probably not 

 comolete. Fourteen small-mammal trapllnes were run, eight In 

 summer and six In fall (Figure 105). Trapping success was highest 

 (3.2 captures/100 tran nights) In grassland and lowest (0.8 

 captures/100 trap nights) In riparian habitats (Table 136). Grass- 

 land areas also yielded the highest number of species {^) . This 

 low success In riparian habitat Is the opposite of trapping 

 success on other study areas (Martin 1980a). Deer mice were the 

 most abundant small-mammal In all habitats. 



A total of seventy-six coyotes were observed on the Klrby area 

 during the study. Coyote aerial observations per hour were 

 highest In fall and the lowest In summer and winter (Table 113). 

 Several bobcats were seen during the study.
