flicker, 1; tree swallow, 1; black-capped chickadee, 1; robin, 2. Rough-winged 

 swallows nested in crevices in the steep concrete retaining wail at the extreme 

 westei-n edge of the plot, and a raven nest was located on a steep rock cliff 

 facing Highway 2 just outside the plot. An active osprey nest was found several 

 km downstream from the plot. Although pi leafed woodpeckers were not observed 

 during the census, one was seen on the plot February 9, 1978, by G. Joslin, and 

 feeding excavations were fairly coinmon in old-growth western red cedar. A brood 

 of 12 common mergansers was seen on June 2 by G. Joslin near the eastern boundary 

 of the plot, and a possible but unverified brood of 7 harlequin ducks was seen June 

 12 by B. Shepard just downstream from the plot. At least seven harlequin ducks 

 were present on the plot; these appeared to represent one pair, one lone female, 

 and four bachelor males. All preferred the head of the falls as a feeding area 

 and the rocky promontory just upstream from the falls as a nesting area, although 

 the entire stretch of river within the plot was used at some time. The first 

 harlequin {a male) was seen in the plot April 29, and the last (a female) was seen 

 June 16. Of the 33 breeding species encountered during the census, the following 

 were restricted to the Kootenai River and/or its shores: mallard, common goldeneye, 

 harlequin duck, common mergdnser, spotted sandpiper, and dipper. The remaining 

 species, with the exception of the swallows, were primarily restricted to terrestrial 

 habitats, whicfi comprised only 60/.' of the plot. More meaningful density estimates 

 for these species in terrestrial habitats may thus be obtained by multiplying the 

 density figures reported above by 1.57. The varied thrush, golden-crowned kinglet, 

 Townsend's warbler, yellow-rumped warbler, and western tanagor occupied priinarily 

 tall, dense, western red cedar and Douglas fir forests south of the railroad right- 

 of-way; the warbling vireo, yellow warbler, MacGil 1 i vray 's warbler, and song 

 sparrow occupied open, shrub-dominated habitats along the right-of-way. Other 

 vertebrates seen on the plot: wandering garter snake, Clliajmxophia elegans) , beaver 

 (Castor aanadenais), chipmunk {Eui-amias spp.), tree squirrel [Tamiasciu^'us 

 hiuisonici-ic), Columbian ground squirrel {Spei'mopkilua ccluipbianus) , northern 

 flying squirrel {Glauaom>js sdbrinuc), mule deer [Odocoileus hcmionus) . This study 

 was part of a wildlife inventory related to a proposed hydroelectric facility, and 

 was funded by Northern Lights, Inc.
