Brown-bellied Stipplethroat

The brown-bellied stipplethroat is 9.5 to 10.5 cm (3.7 to 4.1 in) long and weighs 7.5 to 9.5 g (0.26 to 0.34 oz). Adult males have a mostly gray face and a black throat with white spots. They have an olive-brown crown, upperparts, tail, and flight feathers. Their wing coverts are a darker olive-brown with small white tips. Their breast and upper belly are gray that becomes gray with a clay-colored tinge towards the vent area. Adult females have a mostly pale brownish buff face and throat. Their crown and upperparts are yellowish olive-brown and their tail reddish. Their wing coverts have pink or pinkish buff tips. Their underparts are pale brownish buff that is darker on the flanks and crissum. Juveniles have large spots on the wing coverts that almost form a continuous band.

The brown-bellied stipplethroat is found from eastern Venezuela east through the Guianas and south in Brazil to the Amazon River from the Rio Branco and lower Rio Negro to the Atlantic. It inhabits the understorey of terra firme evergreen forest from sea level to 1,000 m (3,300 ft) though it mostly occurs below 600 m (2,000 ft).

The brown-bellied stipplethroat's diet is not known in detail but includes insects and spiders. It typically forages singly or in pairs, and usually as part of a mixed-species feeding flock. It mostly forages in the forest understory; some studies found that it seldom exceeds 9 m (30 ft) above the ground but others have noted it feeding as high as 15 m (50 ft). It forages mostly in vine tangles, on hanging clusters of dead leaves and in dead leaves and other debris trapped in the vines.
