Pale-vented thrush

The pale-vented thrush (Turdus obsoletus) is a species of bird in the family Turdidae.

It is found in Colombia, Costa Rica, Ecuador, Panama, and Peru. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and heavily degraded former forest.

Ranging from Costa Rica south to western Ecuador, the Pale-vented Thrush is, like a great many Neotropical thrushes, a rather dull and uniformly colored bird. This species is dark rufous-brown above but rather paler below, with an obviously white vent, and a dark-streaked whitish chin and throat. The sexes are similar. It is found in most strata, except the canopy, of humid forest at altitudes ranging from c.500 to 1900 m, but is most frequently encountered at edges and around clearings. Like other thrushes, the Pale-vented Thrush is an omnivore, taking both insects and fruit, and although mainly arboreal it will descend to the ground to feed, and will form small single-species groups, as well as joining mixed-species foraging flocks.
