White-flanked Antwren Myrmotherula axillaris

Very small, active forest bird, rather plump and short-tailed. Male is blackish with obvious white flank and white spotting on wing. Female is pale grayish-brown with buffy spotting on wing; white flanks are usually still obvious. Typically found in pairs, often following a mixed-species flock through the forest, foraging among dead leaf clusters and tangles. Stays at lower or middle levels.
