The Olive-backed Thrush is about an inch smaller than the wood thrush (7
inches), and is uniformly _olive-brown above_. Its _breast, throat,
cheeks_, and _eye-ring_ are _buff_; its _sides gray_. The breast, sides
of the throat, and cheeks are spotted with black.
Note: Its call-note is _puck_;
Song: its song pleasing, with a phrasing that reminds one of the hermit
thrush, but it is louder and less deliberate, and lacks, also, the
hermit's liquid sweetness. The olive-back has a habit of singing
from the pointed top of a tall spruce; near by, on a neighboring
treetop, an olive-sided flycatcher may utter its _Peep here_, or a
hermit may sing in the grove below.
Habitat: The olive-back lives in woods, rather than close to the haunts
of man; it prefers to be near streams and swampy places, as does the
western RUSSET-BACK THRUSH, a bird very similar in appearance and
habits.
Range: The olive-back breeds in Canada and northern United States, and
winters from Mexico to South America.
