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 bright-rumped attila was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the flycatcher in the genus Muscicapa and coined the binomial name Muscicapa spadicea. The specific epithet is from Latin spadiceus meaning "chestnut coloured" or "date-coloured". Gmelin based his description on the "yellow-rumped flycatcher" from Cayenne that had been described in 1783 by the English ornithologist John Latham in his book A General Synopsis of Birds. The bright-rumped attila is now one of seven flycatchers placed in the genus Attila that was introduced in 1831 by the French naturalist René Lesson.

GBIF citizen-science records
It is estimated from how often the Bright-rumped Attila is recorded against all the birds logged in La Amistad International Park (Panama) (1,139 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
