High Quality Content by WIKIPEDIA articles! The Bright-rumped Attila or Polymorphic Attila, Attila spadiceus, is a small passerine bird in the tyrant flycatcher family (Tyrannidae). It breeds from northwestern Mexico to western Ecuador, Bolivia and southeastern Brazil, and on Trinidad. The tyrant flycatchers (Tyrannidae) are a family of passerine birds which occur throughout North and South America, but are mainly Neotropical in distribution. They are now considered the largest family of birds on Earth, with around 400 species. In every country in the Americas, except for the United States and Canada, they are the most diverse avian family. As could be expected from a family this large, the members vary greatly both in shape, patterns and colours. Some Tyrant flycatchers superficially resemble the Old World flycatchers. They are members of suborder Tyranni (suboscines) that do not have the sophisticated vocal capabilities of the songbirds.
