168 OREGON SNOWBIRD
|This species, which is so nearly allied to our Common Snow-bird, is
another of those recently added to our Fauna by Mr. TOWNSEND, from whom
I purchased several specimens. All that I know of its habits is derived
from the following notice given me by Mr. NUTTALL. "It was first
seen by us in the woods of the Columbia, in the autumn and winter,
flitting about in small flocks, always in the forest, never in the open
fields, or on the way-sides. At this time they rarely utter an
occasional chirp, or remain wholly silent. We afterwards saw them
inhabiting the same woods throughout the summer, in diminished numbers,
or in pairs, but I do not recollect hearing them utter any song, though
they are probably not silent in the season of breeding. With the nest,
eggs, and young I am not acquainted."
I have represented the male and female from specimens procured by Mr. TOWNSEND on the Columbia river, on the 5th of October, 1834.

The smaller coverts, secondary coverts and inner secondaries are dusky, with broad light-brown margins; the primary coverts and the rest of the quills brownish-black, narrowly edged with brownish-white. The tail is of the same dark colour as the wings, excepting the two outer feathers on each side, which are white; the second, however, having a part of the outer web dusky, and the third having a white streak on the inner web toward the end.
