The Bahia tyrannulet (Phylloscartes beckeri) is an Endangered species of bird in the family Tyrannidae, the tyrant flycatchers. It is endemic to the Brazilian states of Bahia and Minas Gerais. == Taxonomy and systematics == The Bahia tyrannulet is monotypic. Gonzaga & Pacheco, who discovered and formally described the species, gave it its English name "because it is the only species of Phylloscartes known to be endemic to [the Bahia] area". They assigned the specific epithet beckeri to honor the Bahian biologist Johann Becker "in recognition of his long-standing interest in several fields of natural history". The Bahia tyrannulet is the second to last of four species of genus Phylloscartes described in the late twentieth century. It was preceded by the Alagoas tyrannulet (P. ceciliae) in 1987 and the restinga tyrannulet (P. kronei) in 1992, and followed by the cinnamon-faced tyrannulet (P. parkeri) in 1997. The four were the first members of the genus described since the Minas Gerais tyrannulet (P. roquettei) in 1928, and as of late 2024 no others had been described. == Description == The Bahia tyrannulet is about 12 cm (4.7 in) long and weighs 7.5 to 9 g (0.26 to 0.32 oz). The sexes have the same plumage. Adults have a buffy stripe from the lores that becomes creamy whitish past the eye, a buffy eye-ring, and a dusky line through the eye that continues to the rear and sweeps around the dark yellowish ear coverts. Their crown, nape, back, and rump are bright olive-green with a grayish center to the crown. Their wings are dusky olive with pale yellow edges on the flight feathers. Their wing coverts have yellow tips that form two wing bars. Their tail is dusky olive with thin yellowish olive-green edges. Their throat and breast are dirty whitish with pale yellow flecks. The rest of their underparts are medium yellow with faint olive markings on the sides of the breast and flanks. Both sexes have a dark brown iris, a long, pointed, brown bill with a pearly whitish base to the mandible, and pale gray legs and feet.
