The female is uniformly smaller than the male, and her general coloring, 
particularly the ash of the head and the cinnamon buff of the sides, is duller 
and paler. The rufous brown of the back is also much lighter than in the 
male, being scarcely deeper than the color on the sides. The lores are dusky 
instead of blackish. 
Winter plumage : — My series contains only three specimens in winter plu- 
mage. Of these, a male, taken on November 28, is considerably deeper and 
richer colored than are any of the spring birds, and the rufous brown of the 
neck is more strongly tinged with olive, while the crissum and under tail 
coverts are distinctly buffy. The cinnamon of the sides, however, is duller 
than inspring. The other two specimens are females. They differ from the 
male just described only in having the ash of the throat much lighter, the buff 
of the crissum and under tail coverts deeper, the brown of the back brighter 
and more rufous. They are very much richer colored than any of the spring 
females. 
Individual variations: — The brown of the upper parts varies from faded 
cinnamon brown to deep cinnamon rufous — almost chestnut brown in some 
specimens ; the color of the sides from dull pale cinnamon to light cinna- 
mon rufous. There is a tendency to olivaceous tipping on the feathers of 
the occiput and nape as well as, sometimes, on those of the crown and 
forehead. A specimen taken on May 24 has a narrow but well-defined slaty 
black collar extending from the sides of the neck across the forward part of 
the back or the lower part of the nape. Two other birds, killed at about the 
same time, also show traces of this collar. In ali three the slaty black is con- 
fined to the extreme tips of the feathers. Some of the duller males are dis- 
tinguishable from the brightest females only by the clearer tone of the ash 
on the top and sides of the head.
