The yellow-crested tanager (Loriotus rufiventer) is a species of bird in the family Thraupidae, the tanagers and allies. It is found in Bolivia, Brazil, and Peru. The yellow-crested tanager was formally described in 1825 with the binomial Tanagra rufiventer. It eventually was reassigned to the genus Tachyphonus. A molecular phylogenetic study published in 2014 found that Tachyphonus was polyphyletic. In the subsequent reorganization the genus Loriotus was resurrected for the yellow-crested tanager and two other species. The genus had been introduced in 1821 by the Polish zoologist Feliks Paweł Jarocki.
The IOC, AviList, the Clements taxonomy, and the South American Classification Committee have adopted the new genus. However, in 2016 BirdLife International's Handbook of the Birds of the World (HBW) instead assigned the yellow-crested tanager and the other two species to the genus Islerothraupis and retains them there as of late 2025.
The yellow-crested tanager is monotypic. The yellow-crested tanager is 15 to 16 cm (5.9 to 6.3 in) long and weighs 15.5 to 20 g (0.55 to 0.71 oz). The species is sexually dimorphic. Adult males have a mostly... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yellow-crested Tanager sighting in Manu National Park on a given day, based on 90 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 394th most-seen of the 641 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yellow-crested Tanager in Manu National Park on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-crested Tanager sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Manu National Park, in our data
Manu National Park is the only park on Wallace's Line with enough records to rate Yellow-crested Tanager sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Yellow-crested Tanager is recorded against all the birds logged in Manu National Park (90 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.
