Chapada Flycatcher

The chapada flycatcher (Guyramemua affine) is a Near Threatened species of bird in subfamily Fluvicolinae of family Tyrannidae, the tyrant flycatchers. It is found in Bolivia and Brazil. == Taxonomy and systematics == The chapada flycatcher has a complicated taxonomic history. It was originally described as Suiriri islerorum in 2001, having been previously thought to be a variant of subspecies S. suiriri affinis of the suiriri flycatcher. Based on a study published in 2014 its binomial was changed to S. affinis. (That change necessitated renaming S. s. affinis to S. s. burmeisteri.) A study published in 2017 found that the chapada flycatcher was not related to the suiriri flycatcher but rather to the members of genus Sublegatus. That relationship was not extremely close so the authors proposed a new genus Guyramemua, and because Guyramemua is neuter the specific epithet had to be changed to affine. Taxonomic systems soon adopted the new binomial. == Description == The chapada flycatcher is about 16 cm (6.3 in) long and weighs 21 to 23 g (0.74 to 0.81 oz). It is a medium-sized flycatcher. The sexes have the same plumage. Adults have a gray crown and nape with a light olive wash. They have…
