Power! ine Riqht-of-Way . This habitat is extremely variable, and is 

 typically used by species of adjacent habitats, as well as shrub and 

 edge-loving species such as the yellow warbler, MacGill ivray' s warbler, 

 and song sparrow. Wires on the distribution line were often used as 

 perches by viol?t-green swallows and brown-headed cowbirds. 



Railroad Right-of-Way . Like the powerline right-of-way, the railroad 

 right-of-way is used by species of adjacent habitats for travel and 

 feeding. In the vicinity of the head of the Falls, shrubs along the 

 right-of-way produce oerries abund^intiy which are used extensively by 

 birds and small mammals. Columbian ground squirrel burrows are comr.on 

 on the right-of-way at the head of the Falls, and vellow pine chipmunks 

 are abundant on the right-of-way in summer and fall. 



Orchard . The scattered apple orchards along the Kootenai River 

 were used by species of adjacent habitats and did not support a char- 

 acteristic group of species. Black bears from adjacent coniferous 

 habitats are likely to feed on fallen apples in the fall, although none 

 were observed in this study. 



Open Air . The open air above the river is of course traversed by 

 many bird species (especially raptors and waterfowl) which are crossing 

 the river or moving-up or down river. A number of species, however, use this 

 habitat for feeding on the flying insects which are abundant in summer 

 above the river; these include the black swift, Vaux's swift, violet- 

 green swallow, tree swallow, and rough-winged swallow. Violet-green 

 swallows were especially abundant in the Falls area.
