Juvenal plumage: — (Female, No. 14,572, collection of William Brewster, 
San José del Rancho, July 6, 1887). Above ash brown strongly tinged with 
rusty, the hind back, rump, and upper tail coverts nearly pure rusty; wings 
and tail as in the adult, but with all the tail feathers tipped with rusty, the 
secondaries and greater and middle wing coverts tipped and edged with rusty 
fulvous, the primaries with rusty white ; beneath rusty white, the rusty tinge 
deepest on the abdomen, crissum, and under tail coverts, the entire under parts, 
including the chin and abdomen — but not the middle of the throat, anal 
region, and under tail coverts —thickly spotted with clove brown, these spots 
largest across the breast, but everywhere much narrower and more numerous 
than in old birds. 
Sexual variation: —The sexes do not seem to differ in size, color, or 
markings. 
Seasonal variations: — Autumn birds are much more ashy above and buffy 
beneath than spring specimens. In some of the former, the wing coverts are 
tipped with rusty, and the flanks, abdomen, crissum, and under tail coverts 
with light rusty ochraceous. As the season advances, these colors gradually 
fade, until by April the upper parts become dull ashy brown, while the abdo- 
men and crissum are only faintly tinged with rusty. In June the plumage is 
excessively worn and faded, and the under parts are essentially uniform soiled 
white. . 
Individual variations : — There is much diversity with respect to the spotting 
of the under parts. In the lighter colored birds the spots are small, rounded, 
and confined to the breast and the sides of the throat and body. The darker 
ones have the entire under parts — excepting the under tail coverts, crissum, 
anal region, and a small space on the middle of the throat and abdomen, which 
are always plain — thickly and coarsely marked with deltoid spots which, on 
the breast, are sometimes so large and numerous as to be almost confluent. 
In especially dark specimens the jugulum is usually densely but always finely 
spotted, and there are often a few fine markings on the chin. The whitish 
spots on the tail are ordinarily broad and conspicuous on the inner webs of 
the outer three feathers, extending .50 to .65 of an inch back from their tips, 
but in a few specimens they are restricted and, indeed, almost obsolete, being
