The common black-capped chickadee, so abundant in the eastern States, is in this Territory 
represented by the western titmouse, frequenting the low thickets and trees, where it is always 
busily employed seeking food. I observed its nests near Puget Sound, burrowed in soft rotten 
wood. — C. 
Quite abundant in the valley of the Willamette, also at Fort Vancouver during winter. In 
habits it resembles closely the black-capped chickadee of the Atlantic States,— S. 
PARUS MONT ANUS, Gambel. 
Mountain Tit.

Kep. Birds, p. 394. 
Sp. Ch,— Head and neck above, with under part of head and tlnoat glossy black ; forehead, line above the eye and one below 
it, involving the auriculars, white. These stripes, embracing between them a black line through the eye and confluent with 
the black of the head. Above ashy ; beneath similar, but paler ; the upper part of breast and middle line of belly white. 
Length about 5 inches ; wing, 2. 60 ; tail, 2. 40. 
Hab. — Pacific coast of United States, probably to the Eoclsy mountains ; Fort Dalles, Oregon. 
I obtained one of these birds at Fort Dalles, in February, 1854. It must be very rare in 
that vicinity, as I never succeeded in getting another, — S.

Hab. — Pacific coast of the United States. 
The rufous chickadee is the most abundant species in the forests of this Territory. It 
appears to prefer the dense evergreens, Avhere large parties of them may be found at all seasons, 
busily seeking food among the leaves and branches, ascending even to the highest summits. 
They are generally in company with the ruby-crowned wren, and sometimes with the other 
species of titmice. In April they burrow out a hole in the side of a soft rotten trunk, a few 
feet from the ground. The eggs I have never seen. During the spring they are generally 
seen in pairs, but as soon as the broods can fly, about June, they appear in small families-
