SP. CHAR. Head and neck all round, with jugulum, brownish-saffron,
with a greenish tinge on the nape. Rest of upper parts ashy. Middle
and tips of greater wing-coverts white, forming two bands on the wing;
a third white patch at the bases of the primaries (except the outer
two), and extending forwards along the outer edges. Secondaries edged
externally with olive-green. Inner webs of quills conspicuously edged
with white. Under parts, except as described, white, tinged with
brownish on the sides; a narrow frontal band, and a broad stripe from
this through eye and over ear-coverts, black. Outer tail-feather
white, except at base and towards tip; greater portion of inner web of
next feather also white, much more restricted on the third. Length,
4.60; wing, 2.88; tail, 2.15; tarsus, .75.
A female specimen (14,369), perhaps also in autumnal plumage, has the
saffron replaced by clear yellowish, except on the top of head and
nape, which are olive-green. The black frontal and lateral bands are
replaced by whitish, leaving only a dusky patch on the ears.
HAB. Mexico (both coasts to the southward); Guatemala.
This species is given by Mr. Giraud as occurring in Texas, but it is
possible that he may have been misled as to the true locality. It may,
however, be yet detected along the southern border of the United
States.
Nothing is known of its habits.
