LIST OF THE BIRDS OF FORT SHERMAN, IDAHO. 



From Dr. J. C. Merrill's Notes in The Auk, vol. xiv. 347-357, 1897, and 

 vol. XV. 14-22, 1898. 



Fort Sherman is in northern Idaho, on Coeur d'Alene Lake, which 

 is encircled by hills clad with conifers, and near the Ca?ur d'Alene 

 Mountains. The mouths of streams flowing into the lake afford 

 flats with tules, water grasses, willows, and a few cottonwoods, 

 which are frequented by land birds and a few marsh birds and ducks. 

 At the southern end of the lake the marshy valley of the St. Joseph 

 River affords good nesting and autumnal feeding ground for water 

 birds. When the lake is open a few birds remain on it, going from 

 it to the Spokane River when driven out by ice. The local cli- 

 matic conditions somewhat resemble those of the Northern Cascade 

 Range, and while the avifauna is essentially that of the Rocky 

 Mountains it has Cascade Mountain elements.
