PARUS OCCIDENTALS, Baird. 
Western Titmouse. 
rarus occidentalis, Baird, Gen. Rep. p. 391. 
Sr. Ch.—T arsi 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

Length, 4. 75 to 5. 12 ; extent, 7. 60 ; wing, 2. 40 ; tail, 2. 40. Iris brown, bill black, feet gray. 
Ilab. —North Pacific coast of United States. 
The common black-capped chickadee, so abundant in the eastern States, is in this Territory 
represented by the Avestern titmouse, frequenting the low.thickets and trees, Avhere 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 Avinter. In 
habits it resembles closely the black-capped chickadee of the Atlantic States.—S. 
PARUS MONTANUS, Gambel. 
Mountain Tit. 
Farus montanus, Gambel, Pr. A. N. Sc. 1, April, 1843, 259, (Santa Fe.)— Cassin, Ulust. 1, 1853, 18.— Baird, Gen. 
Rep. Birds, p. 394. 
Sp. Cii.—H ead and neck above, with under part of head and throat 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. 
ffab. —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.

inches; extent, 6.50 to 7.75; wing, 2.36 ; tail, 2.16. 
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-croAvned Avren, and sometimes Avith the other 
species of titmice. In April they burrow out a hole in the side of a soft rotten trunk, a feAv 
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*
