“Adult male.—Top and sides of the head and nape grayish brown, shading into brownish black on the rest of the upper parts and tail; chin whitish; throat and upper breast brownish gray, but considerably paler than the crown; sides of the lower breast and flanks rich chestnut; middle of the breast and belly pure white; under tail-coverts dark gray, tinged with rufous and with wide white middles, widest toward the extremity. Length, 229; wing, 108; tail, 88; tarsus, 30.
“Adult female.—Only differs from the male in having the brownish black upper parts washed with dark olive, most conspicuous on the rump and upper tail-coverts. Length, 221; wing, 108; tail, 82.5; tarsus, 30.
“In the immature male the upper parts resemble those of the female, but most or many of the feathers on the top of the head are brownish black and similar in color to the back of the adult male.
“In a slightly older example the head is mixed with the brownish gray feathers of the adult plumage; in a younger bird the crown is uniform brownish black, and the feathers of the mantle have rufous shaft-stripes. Both these birds have the chest and upper breast mixed with rust-colored feathers spotted with black at the extremity, and perfectly similar to those found in the young of the common blackbird (T. merula).
“An immature female has the top of the head and nape warm dark brown, and the rest of the upper parts dark brown washed with olive, as in the adult female, but few of the feathers of the mantle and wing-coverts have narrow rufous shaft-stripes, and the throat and chest are mostly clad in the rust and black-spotted immature plumage. The nearly adult female differs only from the adult in having the crown blackish brown.” (Grant).
