Rostschwanz-Ameisenschlüpfer

Bestimmung

The rufous-tailed stipplethroat is 10 to 12 cm (3.9 to 4.7 in) long and weighs 9.5 to 12.5 g (0.34 to 0.44 oz). Males are the only members of the genus lacking a contrasting throat. Adult males of the nominate subspecies have a mostly gray face and a whitish throat with some black streaks. Their crown, neck, and upper back are olive-brown; their lower back, rump, and tail are rufous-chestnut. Their wings are brown; their wing coverts are blackish brown with pale buff or white tips. Their breast is gray and their belly and undertail coverts light olive-brown to buff-brown. Adult females have a gray face with a buff tinge. Their throat and breast are ochre and the rest of their underparts brown with an ochre tinge. Both sexes have a red or orange iris and a dark bill. Males of subspecies E. e. septentrionalis look the same as nominate males; females are more ochraceous on their face and underparts.

Taxonomie

The rufous-tailed stipplethroat was described and illustrated by the English zoologist Philip Sclater in 1890 and given the binomial name Hypocnemis erythrura. It was subsequently placed in genus Myrmotherula. Based on genetic and vocal studies it and seven other members of that genus were moved to genus Epinecrophylla created in 2006. All were eventually named "stipplethroats" to highlight a common feature and to set them apart from Myrmotherula antwrens.<p>The rufous-tailed stipplethroat has two subspecies, the nominate E. e. erythrura (Sclater, PL, 1890) and E. e. septentrionalis (Zimmer, JT, 1932).

Verbreitung und Lebensraum

The rufous-tailed stipplethroat's nominate subspecies is found from southeastern Colombia south through eastern Ecuador into northeastern Peru to the Marañón and Amazon rivers and east into extreme northwestern Brazil. Subspecies E. e. septentrionalis is found in eastern Peru south of the Marañón and in west-central Brazil south of the Amazon. The species primarily inhabits terra firme evergreen forest in the lowlands and foothills, but also transitional forest and várzea. In elevation it occurs below 600 m (2,000 ft) in most of its range and locally up to 900 m (3,000 ft).
