Turdus albicollis
The white-necked thrush is 20.5 to 26 cm (8.1 to 10 in) long and weighs 40 to 84.5 g (1.4 to 3.0 oz). The sexes have the same plumage. Adults of the nominate subspecies T. a. albicollis have a blackish brown head with a blackish-streaked white throat and a yellow to orange eye-ring. Their upperparts, wings, and tail are dark brown. They have a white crescent below the throat, a buff-gray breast and upper belly, brown-washed orangey flanks, and a white lower belly and undertail coverts. They have a brown iris, a yellowish bill, and pinkish brown legs and feet. Voice: "The White-necked Thrush has a melodious song that varies somewhat across its broad range. While foraging it also produces a variety of abrupt calls." In Venezuela its song is written as "churrwerr . . eeerrr . . weeerr . . eerr's . .; the paired, sing-song phrase are hypnotic...and are not identical to each other". There its alarm call is "a rough jjig-wig or jjig-wig-wig".
