The yellow-legged thrush (''Turdus flavipes'') is a songbird of northern and eastern South America. In recent times, it is increasingly often placed in the genus ''Turdus'' again,〔ffrench ''et al.'' (1991), Clement & Hathaway (2000), Hilty (2003), BLI (2009)〕 however some taxonomists place this species in the genus ''Platycichla'' based on morphology. The South American Classification Committee of the American Ornithologists' Union places it in the genus ''Turdus'', as does the International Ornithological Committee. ==Description== This thrush is long and weighs . Both sexes have yellow legs and eye-ring. The male has a yellow bill and its plumage is usually black with a slate-grey back and lower underparts. However, the hue of the grey areas varies, and the male of one of the five subspecies, ''P. f. xanthoscelus'' of Tobago, is all-black, resembling the male Eurasian blackbird (''Turdus merula''). Females have a dull bill, warm brown upperparts and paler underparts. The juvenile male is brownish with black wings and tail, while the juvenile female resemble the adult female, but is duller, flecked with orange above and spotted and barred with dark brown below.〔ffrench ''et al.'' (1991), Clement & Hathaway (2000), Hilty (2003)〕 The song of the male is musical phrases, ''sreep, sreee, sree, sreee'', again somewhat resembling that of the Eurasian blackbird, but sometimes including some imitation of other birds songs. The typical call is a sharp ''srip'' and a peculiar ''seeet'' given in alarm.〔
