- Turdus chiguanco
Identification
Length 27-28 cm, weight 105-110 g
A medium-large dark sooty or brownish thrush with an orange bill. Easily confused with the larger and proportionally longer-tailed Great Thrush. Males of that species have an orange-yellow eye-ring unlike the Chiguanco Thrush of the subspecies T. c. chiguanco and T. c. conradi, but the southern T. c. anthracinus (from Bolivia and southwards) has an orange-yellow eye-ring. The plumage of T. c. anthracinus is darker than the overlapping subspecies of the Great Thrush, but elsewhere the opposite is true.
