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 Manaus on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 103rd most-seen of the 116 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
June and September
In those months about 10% of wildlife watchers report a Bright-rumped Attila in Manaus on a given day, against under 5% in July–August and October–May, the lowest months. Those are among Manaus's driest months, with about 95 mm of rain a month against 270 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.
2nd of 4
Of the 4 cities where we can rate Bright-rumped Attila sightings, Manaus ranks 2nd at under 5%. The best odds are in Belém (Brazil, about 10%).
Same family: Tyrannidae
The closest relatives of the Bright-rumped Attila that you can see in Manaus (family Tyrannidae, Tyrant Flycatchers) are Great Kiskadee (about 80%), Tropical Kingbird (about 70%) and Spotted Tody-Flycatcher (about 60%), 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 Manaus (7 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.
