Varied Thrush, Ixoreus naevius is a species of thrush native to the Pacific Northwest, California and Alaska. Its contrasting black-and-orange plumage and eerie, penetrating song make it one of the most distinctive birds of Northwestern forests.^[2]

The Varied Thrush is a large, brightly-,^[2] uniquely- and strikingly-coloured thrush,^[3] with a total length of 19.0–26.5 cm (7.5–10.4 in),^[2] a wingspan of 35.56–40.64 cm (14.00–16.00 in)^[3] body mass 65–100 g, depending on sex and location.^[2]

it has orange underparts, wing bars and eyebrows. Females have a dusky-brown cast to the upperparts.

Taxonomy[]

It is often merged into Zoothera but, apart from underwing pattern, plumage very different. Geographical variation slight and mostly clinal; carlottae and godfreii possibly not tenable.^[4]

Related and similar species[]

American Robin has a broken white eye-ring, solid grey wings without wingbars, white throat with black striping, chestnut-orange underparts without a breast band or scalloping, yellow bill and lacks orange eyebrows. It also frequents dense and damp coniferous forests and undergrowth, unlike the American Robin.^[3]

Distribution/habitat[]

The Varied Thrush breeds from Alaska to California in forests "where spruce trees and alders and crowding ferns contend for a footing, and where a dank mist drenches the whole with a fructifying moisture."^[5]
