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.

With luck
About 10% of wildlife watchers report a Bright-rumped Attila sighting in Belém on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 75th most-seen of the 144 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
October
In that month about 20% of wildlife watchers report a Bright-rumped Attila in Belém on a given day, against under 5% in January–March, July–August and November, the lowest months. That is one of Belém's driest months, with about 75 mm of rain against 440 mm in March.
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.
Yes
Of the 4 cities where we can rate Bright-rumped Attila sightings, Belém has the highest daily chance: about 10%. Next come Manaus (Brazil, under 5%) and San José (Costa Rica, under 5%).
GBIF citizen-science records
It is estimated from how often the Bright-rumped Attila is recorded against all the birds logged in Belém (18 verified sightings), 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.
