"Adult male.--Above tawny-yellow and black, the latter predominating

and occupying the center of the feathers, the sides of which are

tawny-buff, freckled and irregularly barred with black; lower back,

rump, and upper tail-coverts pale tawny-buff, mottled with bars or

cross-lines of dusky brown; marginal wing-coverts rufous, regularly

barred across with black; median and greater coverts tawny-buff,

with irregular bars or arrow-shaped markings of blackish brown, much

less pronounced on the greater coverts, all of which have a rufescent

tinge near the base; alula, primary-coverts, and quills blackish,

barred with rufous, the bars somewhat broken up on the inner webs

of the quills, which are also paler; the inner secondaries like the

scapulars, being tawny-buff on their edges and mottled in a similar

manner; tail-feathers tawny-buff, irregularly mottled with black bars

or cross-markings, more pronounced on the middle of the feathers;

crown of head uniform black, with a frill of erectile plumes on the

nape, these being tipped with tawny-buff, and the pale tips crossed

with lines of black; eyebrow, sides of face, and sides of the neck

tawny-buff, the eyebrow uniform except on the under edge, where the

feathers are barred with black; ear-coverts scarcely marked at all,

but the plumes of the sides of the neck narrowly barred with black,

and elongated into a frill which covers the hind neck, the latter

being clothed in dense down of a tawny-buff-color; the feathers below

the eye, and a streak along the cheeks and down the sides of the neck,

black; malar line of feathers and throat creamy white, with a central

line of reddish buff feathers slightly mottled with black bases; the

lower throat also creamy white, with four or five tolerably defined

broad lines of tawny-buff and black-mottled feathers; the lower part of

the ruff on the fore neck with narrow wavy lines of black; the breast

covered with down of a tawny-buff-color, and hidden by a large patch

of loose plumes on each side of the chest, which are mostly black

with tawny-buff margins; remainder of under surface creamy white,

streaked with black centers to the feathers, the black markings

slightly broken up with mottlings of tawny-buff; thighs and under

tail-coverts with scarcely any markings whatever; under wing-coverts

and axillars tawny-buff, the former narrowly lined with blackish, the

axillars more distinctly barred with dusky blackish. 'Bill greenish

yellow; legs and feet yellowish green; claws dark brown; iris yellow;

bare space before the eye yellowish green.' (Seebohm.) Length, about

610; culmen, 69; wing, 330; tail 112; tarsus, 96.

"Two of the three specimens collected by Mr. Robert Bergman at Yokohama

are apparently young birds and have the primary-coverts and quills

almost uniform, with a certain amount of rufous mottlings confined

to the inner webs; in this state of plumage B. stellaris has a great

resemblance to B. poeciloptilus but is always to be distinguished

from the last-named bird by the tawny-colored frill on the sides of

the neck, instead of the smoky brown one peculiar to the Australian

bird." (Sharpe.)
