Male.--General color glossy black; a broad superciliary line from
above lores to nape white; breast, abdomen, and crissum white with a
faint buff wash on flanks; feathers of thighs brown with white tips;
wings black; axillars and wing-lining white; tail black, outer pairs
of rectrices with narrow white tips, wanting in one specimen. Iris
dark; bill black; legs light flesh-color; nails light brown. Length,
165 mm. A male from Masbate measures: Wing, 84; tail, 73; culmen from
base, 20; bill from nostril, 12; tarsus, 28; middle toe with claw,
23. A male from Ticao, wing, 79; tail, 66; culmen from base, 18;
bill from nostril, 11; tarsus, 27; middle toe with claw, 22.
"A young male, nearly adult, has a few white feathers on chin and
throat and a faint wash of light buff on the flanks. A much younger
bird has many of the feathers of the back tipped with rusty brown
and the greater wing-coverts and quills washed with the same color;
chin and throat almost pure white; an ill-defined black collar;
the entire under surface washed with light buff, deeper on the flanks.
"This well-marked species is extremely rare in Masbate. It feeds
in dense thickets in the deep woods and we never heard it utter a
note. The Luzon bird, C. luzoniensis, has a superciliary stripe,
but this stripe is not nearly so broad as in this species, and as
the strongly marked superciliary line is one of the most noticeable
characters of the Masbate bird we have named it accordingly." (Bourns
and Worcester.)
