Lawrence's Thrush

Lawrence's thrush is 21.5 to 23 cm (8.5 to 9.1 in) long and weighs about 73 g (2.6 oz). The species is sexually dimorphic. Adult males have a mostly olive-brown head with a rufous tinge. They have a yellow eye-ring and a white throat with dark streaks. Their bill is yellow. Their upperparts, wings, and tail are rufous-tinged olive-brown. Their breast and flanks are rufous-drab and their belly and vent white. Adult females are similar to males but have a paler breast and flanks and a duller bill. Both sexes have a dark iris and pinkish brown legs and feet. Juveniles have orange-buff streaks on their upperparts and two orange wing bars. Their underparts are buffy with heavy brown mottling.

Lawrence's thrush is a bird of the upper Amazon Basin. In Venezuela it is found in southeastern Bolívar and far southwestern Amazonas states. From Amazonas its range continues west and south through southern Colombia, eastern Ecuador, and eastern Peru into extreme northwestern Bolivia. From Venezuela its range also extends into northwestern Brazil. From the other countries its range extends east across Brazil south of the Amazon River to Tocantins with a southern boundary in Mato Grosso. Though one source includes Guyana in its range the South American Classification Committee has no records in that country. Lawrence's thrush inhabits humid forest, primarily terra firme (including that on sandy soil) and also várzea and the ecotone between them. In elevation it ranges up to 1,200 m (3,900 ft) in Venezuela, to 500 m (1,600 ft) in Colombia, to 600 m (2,000 ft) in Ecuador, to 700 m (2,300 ft) in Peru, and to 800 m (2,600 ft) in Brazil.

The diet of Lawrence's thrush has not been studied but is known to include fruit. It forages mostly from the forest's mid-level to its canopy though sometimes on the ground. It occasionally joins mixed-species feeding flocks.
