Great Thrush Turdus fuscater Scientific name definitions

The common name of this species is well-deserved: Great Thrush is the largest member of this cosmopolitan genus, with some subspecies reaching 175 g, twice the weight of the average species of Turdus thrush. Great Thrush is often the most common thrushs in humid Andean habitats, especially around human activity, above 2000 m from Venezuela south to western Bolivia. The seven subspecies are of slightly different size and color tone, but all are separable from other monotone Andean Turdus by their very large size and, in the male, by the conspicuous eyering. Great Thrush is most similar to Chiguanco Thrush (Turdus chiguanco), but in addition to previous field marks, the Great Thrush is darker and grayer, less brown, than Chiguanco Thrush.
