II. BIRDS. 
RicHuanpsow's Pewee ( Contopus Richardsonii). 
Frycatcners (Empidonax pusillus, obscurus, and mini- 
mus). These being the species found at Fort Bridges, I 
Suppose one or more of them to have been among the small 
flycatchers I saw in the mountains. They were exvaedingly 
shy, and though I shot one or two I did not find them, as 
they fell or hid among thick bushes. 
SWALNSON’S THRUSH (Turdus Swainsonii). I heard the

Rosin Tarvusu (T. migratorius). Not abundant, but seen 
all along the route except in the dense forests. Milk 
river I found a nest, with eggs, built in a split trunk of a 
half fallen tree. 
OngEGON Rosin (T. nevius). I found this beautiful thrush 
. common near the summit of the Coeur d'Alene Mountains 
about September 10th, frequenting the exceedingly dark and 
damp spruce forests, which seemed to be its favorite summer 
residence as at the mouth of the Columbia river. I was 
surprised to find many of them about Fort Vancouver as 
early as October 28th, where I did not see them in 1853 
until December. There had been an uncommonly early fall
