Princeton University Press (2001), {{ISBN|978-0-691-08852-5}}</ref> This thrush has the white-dark-white underwing pattern characteristic of ''Catharus'' thrushes. Adults are brown on the upperparts. The underparts are white with brown on the flanks; the breast is lighter brown with darker spots. They have pink legs and a light brown eye ring. Birds in the east are more olive-brown on the upperparts; western birds are more reddish brown. This bird's song is a hurried series of flute-like tones spiralling upwards.
