"Western TUmonse, 



Parus occidentals, Baird, Gen. Ecp. p. 391. 



Sp. Ch. — Tarsi lengthened. Tail graduated ; outer feather about .25 of an inch shorter than the middle. 



Above dark brownish ash ; head and neck above and below black, separated on the sides by white ; beneath light dirty, 

 rusty yellowish brown, scarcely whiter along the middle of body. Tail and wings not quite so much edged with whitish as

Ilah. — North Pacific coast of United States. 



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.

Sp. Ch. — Head and neck above, with under part of head and throat, glossy black ; forehead, line above the eye and one

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. 



Uab — Pacific coast of United States, probably to the Rocky 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.

 Hub. — Pacific coast of United States. 



The rufous chickadee is the most abundant species in the forests of this Territory. It 

 appears to prefer the dense evergreens, where 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.
