Adult male in winter plumage. General colour above ruddy-brown, the head like the back; 
wing-coverts like the back ; bastard-wing, primary-coverts, and quills dark sepia-brown, externally 
ruddy-brown like the back, the innermost secondaries resembling the latter; lower back, rump, and 
upper tail-coverts decidedly more olive than the rest of the back; tail blackish, with a slight ashy 
shade; lores dusky; sides of face dark ruddy-brown, with paler hair-like shaft-lines ; chin and 
throat white, with broad triangular spots of black, producing a streaked appearance; cheeks with a 
broad white streak above the malar line; on the lower throat a large patch of pure white; fore-neck, 
breast, and sides of body earthy-brown, tinged with ochraceous, the thighs also brown; centre of 
abdomen and under tail-coverts pure white, the latter mostly edged with dark brown, especially 
towards the base ; axillaries and under wing-coverts light ochraceous-brown like the sides of the 
body, but with a distinct tinge of golden buff; quill-lining sepia-brown, ashy along the inner webs, 
inclining to whitish near the base of the latter; bill dark. Total length 9:3 inches, culmen 0'9,

Adult female. Similar to the male in colour. Total length 9 inches, wing 5:0. 
Young. Rather greyer than the adults in winter, the upper surface being streaked with tawny- 
buff centres to the feathers. 
For the proper understanding of the various plumages through which this species passes I have 
taken the series collected by Mr. Salvin and Mr. Godman in Guatemala. These range from the 
months of August to January, and in the first of these months Mr. Salvin obtained two young birds 
which were completing their moult into the first winter plumage. An old bird in freshly-moulted 
plumage was also obtained by them in August, and has a blackish bill. Birds procured by the same 
naturalists in October, November, and December are very similar in colour to the August bird, but 
have a slight inclination to yellow on the lower mandible, as well as a faint tinge of grey on the crown 
in the December birds. Those killed in January, however, are very perceptibly greyer on the head 
and have the bill yellow. Unfortunately there are no birds obtained from Guatemala between 
January and August in the collection; but it is quite evident that the bill turns yellow in summer 
(which is never the case with T. tristis), and the upper plumage becomes slaty-grey, the olive or 
brown tint on the back gradually disappearing and becoming abraded. This fact is abundantly 
proved by the large series in the Salvin-Godman Collection from other parts of Central America.
