Rufous-tailed Flatbill

The rufous-tailed flatbill (Ramphotrigon ruficauda) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay. == Taxonomy and systematics == The rufous-tailed flatbill was originally described as Platyrhynchus ruficauda. The genus Ramphotrigon was long thought to be closely related to genera Tolmomyias and Rhynchocyclus, whose members also have wide bills. However, studies published in the early 2000s found that it is more closely related to genus Myiarchus. The rufous-tailed flatbill is monotypic. == Description == The rufous-tailed flatbill is 15 to 16 cm (5.9 to 6.3 in) long and weighs about 17 to 26 g (0.60 to 0.92 oz). The sexes have the same plumage. Adults have an olive-green crown, a faint pale line behind the lores, and a faint pale eye-ring on an otherwise dark olive-green face. Their upperparts are mostly dark olive-green with bright rufous uppertail coverts. Their wings are mostly blackish with wide bright rufous edges on the flight feathers and tips on the coverts; the latter show as two wing bars. Their tail is bright rufous. Their throat is grayish, their breast mixed olive-green and yellow, their belly olive-green…
