Description.—Head, wings, and tail brownish black; the remaining portions of upper surface brownish olive; under surface pale rufous, obscure on the breast; throat white, striped with black; bill and feet dull yellow: total length 10·5 inches, wing 7·5, tail 4·0. Female similar.
Hab. Patagonia and Chili.
This Thrush, which I met with on the Rio Negro of Patagonia, so closely approximates to T. rufiventris in colour, language, and habits, that the casual observer finds it difficult to distinguish one from the other. Its nest and eggs are also precisely like those of its northern representative. The song is, however, much poorer, and reminds one of the first attempts of a young bird. That a member of so melodious a family should have so inferior a song I attribute to the fact that Thrushes (unlike the songsters of other genera) sing only in the warm season and when the air is calm. In the southern portion of the South-American continent violent winds prevail in summer, so that this southern Thrush sings perhaps less frequently than any other song-bird, and appears to be losing the faculty of song altogether.

“I have noticed this bird in the provinces of Mendoza, San Juan, San Luis, Cordova, and Catamarca, where it is much esteemed as a cage-bird on account of its beautiful whistle. In Mendoza it goes by the name of ‘Zorsal,’ in Catamarca and Cordova by that of ‘Merlo,’ and in Andalgala (Catamarca province) ‘Chocoyno.’”—White, l. s. c.
“Very common at Mendoza, Cordova, and Tucuman, and met with among the shady trees of the promenades: has a better song than our Blackbird, which is heard at a distance, especially in the evening. Called ‘Crispin’ in Tucuman.”—Burm. l. s. c.
