E very particular relating to the history and economy of this species of Rock-Thrush appears to be as much
unknown or buried in obscurity as it was when I published my ‘ Century of Birds from the Himalaya Mountains,’
thirty-three years ag o ; even Mr. Jerdon merely states that “ This Thrush has hitherto, I believe,
only been found in the Himalayas, generally at a considerable elevation. It is not rare about Darjeeling,
frequenting high forest, feeding on the ground on various insects, and, when disturbed, taking refuge in
high trees.” Mr. Jerdon adds in a note, that he had lately shot it on the Khasia Hills.
The male has the crown of the head, nape, lesser wing-coverts, rump, and upper tail-coverts light blue;
back dull dark blue, with a crescent of black near the tip of each feather; greater wing-coverts, primaries,
and secondaries dull black, washed with dark blue on the basal portions of their outer webs; the last row
o f lesser wing-coverts tipped with brownish white, forming a faint line across the wing; tail dull black,
glossed with dark blue on the two centre feathers and the outer webs of the remainder; lores, ear-coverts,
and sides of the neck black; throat dark blue, each feather tipped with lighter blue; under surface of the
body, under tail-coverts, and thighs deep chestnut; irides brownish black; bill and legs black.
The female is ashy brown above, with darker edgings to some of the feathers; lores, ear-coverts, and
sides of the neck mottled with fulvous and brown; under surface fulvous, with a crescent of dark brown at
the tip of each feather.
The young, like the members of the Saancolince, is beautifully spangled all over with spots of buff on a
dark ground, the former being the hue of the centres, and the latter that of the margins of the feathers of
the upper and under surface and the lesser wing-coverts, while the greater coverts and secondaries are blue,
margined with deep buff at the tip, and the upper tail-coverts are rich red, tipped with dark brown.
It will be seen that I have figured a young male in this particular dress, and an adult male, both of the
size of life, with a female on a reduced scale in the distance.
