Bicknell’s Thrush

Bicknell's thrush (Catharus bicknelli) is a medium-sized thrush, at 17.5 cm (6.9 in) and 28 g (0.99 oz).

While very similar in appearance and vocalization to the gray-cheeked thrush (Catharus minimus), the two species differ slightly in their morphology and vocalizations, although they have with completely different breeding ranges. It was named after Eugene Bicknell, an American amateur ornithologist, who made the first scientific discovery of the species on Slide Mountain in the Catskills in the late 19th century.
