Rufous-tailed Stipplethroat

The rufous-tailed stipplethroat (Epinecrophylla erythrura), formerly called the rufous-tailed antwren, is a species of insectivorous bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, Ecuador, and Peru. == Taxonomy and systematics == 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. The rufous-tailed stipplethroat has two subspecies, the nominate E. e. erythrura (Sclater, PL, 1890) and E. e. septentrionalis (Zimmer, JT, 1932). == Description == 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…
