"Adult (type of species).--Above tawny-rufous, the feathers mesially
dark brown, giving a closely striped appearance; the wing-coverts
rather darker, some of the scapulars and greater-coverts externally
creamy buff, forming a kind of longitudinal bar down the latter;
entire head and auricular-tufts colored like the back, but somewhat
more narrowly streaked; quills dull brown, tipped with fulvous, more
plainly on the secondaries, the primaries spotted on the outer and
barred on the inner web with pale tawny-rufous, the bars more distinct
on the secondaries; tail-feathers dull brown, tipped with fulvous and
crossed with a few bars of tawny-buff, the middle feathers nearly
uniform, with only one bar and indications of a second, the bars
gradually increasing in number toward the outer tail-feather, which
has five bars on the inner web, and is externally tawny-buff; lores
white, the anterior bristles black toward tip; sides of face tawny,
with white shafts; facial disk tawny, with central streaks of brown to
the feathers, which are fulvous at base; under surface of body buffy
white, longitudinally streaked with dark brown centers to the feathers,
each mesial streak having a narrow edging of rufous on each side,
and decreasing in width toward the abdomen and under tail-coverts,
the tarsal feathers entirely uniform; under wing-coverts buffy white,
the outermost longitudinally spotted with dark brown, the greater
series whitish at base, brown at tip, resembling the inner lining of
the wing. Bill horn-blue at base, yellow at tip; feet fleshy brown,
