The opal-rumped tanager (Tangara velia) is a species of bird in the family Thraupidae. It is found in the Amazon and Atlantic Forest of South America. The population of the Atlantic Forest has a far paler chest than the other populations, and has often been considered a separate species as the silvery-breasted tanager (Tangara cyanomelas). Today most authorities treat it as a subspecies of the opal-rumped tanager.
In 1743 the English naturalist George Edwards included an illustration and a description of the opal-rumped tanager in his A Natural History of Uncommon Birds. He used the English name "Red-belly'd Blue-bird". Edwards based his hand-coloured etching on a specimen owned by the Duke of Richmond that had been collected in Suriname. When in 1758 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the tenth edition, he placed the opal-rumped tanager with the wagtails in the genus Motacilla. Linnaeus included a brief description, coined the binomial name Motacilla velia, and cited Edwards' work. Linnaeus provided no explanation for the specific epithet; it is perhaps a misprint for the Ancient Greek elea, a small bird mentioned by Aristotle. The opal... Wikipedia →

Rare
Under 5% of wildlife watchers report an Opal-rumped Tanager sighting in Anavilhanas National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 231st most-seen of the 291 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report an Opal-rumped Tanager in Anavilhanas National Park on a given day, against under 5% in October to June, the lowest months. Those are among Anavilhanas National Park's driest months, with about 90 mm of rain a month against 340 mm in March.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Opal-rumped Tanager sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 8
Of the 8 parks where we can rate Opal-rumped Tanager sightings, Anavilhanas National Park ranks 5th at under 5%. The best odds are in Yasuní National Park (Ecuador, about 20%), Cuyabeno Wildlife Reserve (Ecuador, under 5%) and Manu National Park (Peru, under 5%).
GBIF citizen-science records
It is estimated from how often the Opal-rumped Tanager is recorded against all the birds logged in Anavilhanas National Park (11 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.
