Male.--Upper parts, sides of head and neck, chin, throat, and chest

blue, this color much obscured by gray, brown, and blackish tips

to the feathers; lower breast, abdomen, crissum, and thighs deep

chestnut, obscured by whitish tips and blackish subterminal bars;

axillars and wing-lining chestnut; wings and tail black, the feathers

edged with blue and tipped with white. Length, about 215; wing,

125; tail, 81; culmen from base, 21; bill from nostril, 14; tarsus,

27.5. This plumage is the one usually found in winter birds in the

Philippines. "At the end of winter the white fringes and subterminal

black bars on the blue parts of the plumage are entirely lost, and

the marks on the chestnut parts are also removed by abrasion in great

measure, but never entirely." (Oates.)

"The female much resembles the autumn plumage of the male, except

that the blue of the upper parts is much duller and the whole of the

under parts are pale whitish brown, suffused with pale buffish brown

on the axillaries and under wing- and tail-coverts; each feather on

the under parts has a dark brown subterminal transverse band, which on

the throat is continued on the margins of the feathers; the axillars

and the under tail-coverts have several transverse dark bars. After

the autumn molt the only perceptible difference in the female is that

the pale brown margins of the feathers are somewhat longer. Males of

the year scarcely differ from adult females, excepting in having the

ground-color of the under parts, especially on the breast and belly,

tinged with blue. Females of the year have the ground-color of the

upper parts brown, only slightly tinged with blue on the wing-coverts,

rump, and upper tail-coverts. Young in first plumage differ very

slightly from the females of the year, but have scarcely a trace of

blue." (Seebohm.)

A young female from Calayan is brown, slightly washed with dull blue

on mantle and back; feathers of mantle, back, and tail-coverts with

subterminal blackish bars and gray tips; under parts ocherous buff the

feathers with subterminal blackish bars; wings black, the feathers

tipped with white and edged with gray, tail similar; wing-lining,

axillars, and crissum richer ocherous barred with black.

"Curiously enough this bird is called 'solitaria' by the natives of

Negros on account of its habits. Always seen singly or in pairs. Common

in the villages, especially about old churches. Also abundant on the

rocks along the seashore and in open country in general; never found

in the forest. Iris dark brown; bill, legs, feet, and nails black;

food, insects.

"Six males average, 210 in length; wing, 111; tail, 85; culmen, 23;

tarsus, 27; middle toe with claw, 26. Four females, length, 210;

wing, 111; tail, 84; culmen, 23; tarsus, 27; middle toe with claw,

27." (Bourns and Worcester MS.)

A specimen from Bataan Province, Luzon, appears to be much nearer

Petrophila cyanus (Linnæus) than P. manillensis; the under parts

are blue with the chestnut restricted to the axillars, wing-lining,

crissum, and a few feathers in the middle of abdomen.

Subfamily RUTICILLINÆ.

Nearly all the members of this subfamily are considerably smaller than

any of the Turdinæ. There is much diversity in the color pattern as

well as in the length and shape of the tail. The species are mostly

terrestrial.
