 with whitish.) Hood and upper part of nape continuous chestnut ; a line of the same from behind the eye. Sides of head 

 and neck ashy. A broad light superciliary band. Beneath whitish, with a small circular blotch of brownish in the middle 

 of the upper part of the breast. Edges of tail feathers, primary quills, and two bands across the tips of the secondaries, 

 white. Tertiaries nearly black ; edged externally with rufous, turning to white near the tips. Lower jaw yellow ; upper 

 black. Length, 6.25 inches ; wing, 3. 



Hob. Eastern North America to the Missouri ; also on Pole creek and Little Colorado river, New Mexico. 



Mentioned by Townsend as an inhabitant of Oregon. I shot a bird in January, 1855, at 

 Fort Dalles, which, upon comparing with the description of E. canadensis, in Audubon s 

 Synopsis, appeared to belong to that species. The skin was unfortunately lost. S. 



I saw once, in winter, some sparrows which I supposed to be the tree sparrow, but obtained 

 no specimens. This was on the coast, and it is likely that they visit the interior at that season 

 in great numbers, as it is mentioned by Townsend in his list of Oregon birds. C.

SP. CH. Rump, back of neck, and sides of neck and head, ashy. Interscapular region with black streaks, margined with 

 pale rufous. Crown continuous and uniform chestnut. Forehead black, separated in the middle by white. A white 

 streak over the eye, and a black one from the base of the bill through and behind the eye. Under parts unspotted whitish, 

 tinged with ashy, especially across the upper breast. Tail feathers and primaries edged with paler, not white. Two narrow 

 white bands across the wing coverts. Length, 5.50 ; extent, 8.50; wing, nearly 3.00. Iris, brown : feet, pale brown ; bill, 

 black. 



Hab. North America, from Atlantic to Pacific. 



The chipping sparrow frequents similar situations as in the east, and about houses shows the 

 same familiar confidence as in the Atlantic States. C. 



This bird is common throughout.the two Territories. I have obtained and preserved many 

 skins. No appreciable difference in the habits of western individuals from those of the 

 Atlantic coast. Extremely abundant in the open districts on the Columbia river, as well as 

 upon the gravelly prairies of the Puget Sound district. S.
