Grey-cheeked Thrush

The grey-cheeked thrush (Catharus minimus) is a medium-sized thrush. This species is in length, and has the white-dark-white underwing pattern characteristic of Catharus thrushes. It is a member of a close-knit group of migrant species together with the veery and Bicknell's thrush; it forms a cryptic species pair with the latter. The grey-cheeked thrush is all but indistinguishable from Bicknell's thrush except by its slightly larger size and different song. The two were formerly considered conspecific. Of all the American spotted thrushes, the grey-cheeked has the most northern breeding range. The grey-cheeked thrush is slightly larger than other Catharus thrushes, about 16 to 17 cm in height. The bird can be identified by its grayish face, partial pale eyering, drab gray-brown upperside and extensively dusky flanks. The area between the eye and the beak is grayish as well, but the area running from the beak to above the eye is grayish white. The gray-cheeked thrush is nearly identical to the Bicknell's Thrush.
