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.

Rare
Under 5% of wildlife watchers report a Bright-rumped Attila sighting in Celestún Biosphere Reserve on a given day, based on 66 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 151st most-seen of the 297 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Bright-rumped Attila in Celestún Biosphere Reserve on a given day, against under 5% in April and September–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Bright-rumped Attila sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
45th of 57
Of the 57 parks where we can rate Bright-rumped Attila sightings, Celestún Biosphere Reserve ranks 45th at under 5%. The best odds are in Cockscomb Basin Wildlife Sanctuary (Belize, about 40%), Tikal National Park (Guatemala, about 30%) and Pico Bonito National Park (Honduras, about 30%).
Same family: Tyrannidae
The closest relatives of the Bright-rumped Attila that you can see in Celestún Biosphere Reserve (family Tyrannidae, Tyrant Flycatchers) are Tropical Kingbird (about 60%), Social Flycatcher (about 50%) and Vermilion Flycatcher (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bright-rumped Attila is recorded against all the birds logged in Celestún Biosphere Reserve (66 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.
