Zosterornis nigrocapitata McGregor and Worcester, Hand-List
(1906), 82, (part).
Zosterornis affinis McGregor, Phil. Journ. Sci. (1907), 2,
sec. A, 292.
Luzon (Celestino).
Male (type).--Forehead and crown black, the shafts obscurely whitish;
a small patch of chestnut behind each eye next to the black crown;
general color above dull olive-gray, feathers of neck and mantle with
conspicuous, narrow, whitish shaft-lines; rump uniform; a narrow ring
around eye, ear-coverts, and cheeks gray with pale yellow shaft-lines;
chin, throat, and fore breast pale lemon-yellow, the chin heavily
washed with chestnut-rufous which becomes gradually less on throat
and disappears on breast; middle of breast and abdomen very pale
yellow, their sides gray, overlaid with a faint yellow wash; under
tail-coverts pale yellow; wings blackish brown, outer edges of quills
lighter and inner edges whitish; median and lesser coverts with light
shaft-lines; upper tail-coverts dull olive-brown; rectrices dark
brown, except the outermost feathers, their outer webs edged with
olive-brown, all but the center pair tipped with white, increasing in
extent toward the outermost feather which has its outer web almost
entirely white. Length, 152; wing, 68; tail, 61; culmen from base,
17; bill from nostril, 10; tarsus, 19.
This species is similar to Z. nigrocapitatus, but is slightly larger
and the back is distinctly olivaceous; the reddish brown of chin and
upper throat are diffused over these parts instead of forming a patch
on each side. The only known specimen, a male, was taken in Bataan
Province, Luzon, December 3, 1904.
Genus MIXORNIS "Hodgson" Blyth, 1842.
Rictal bristles nearly as long as bill from nostril; culmen from base a
little shorter than tarsus; nasal opening oval and with no overhanging
membrane; feathers of lower back long, decomposed, and hair-like,
without stiff shafts, the longest reaching to tips of tail-coverts;
entire body plumage soft and decomposed.
