The white-shouldered tanager (Loriotus luctuosus) is a species of bird in the family Thraupidae, the tanagers and allies. It is found from Honduras to Panama, on Trinidad, and in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay.
The white-shouldered tanager was formally described in 1837 with the binomial Tachyphonus luctuosus. A molecular phylogenetic study published in 2014 found that Tachyphonus was polyphyletic. In the subsequent reorganization the genus Loriotus was resurrected for the white-shouldered 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 North and South American Classification Committees have adopted the new genus. However, in 2016 BirdLife International's Handbook of the Birds of the World (HBW) instead assigned the white-shouldered tanager and the other two species to the genus Islerothraupis and retains them there as of late 2025.

Rare
Under 5% of wildlife watchers report a White-shouldered Tanager sighting in Rincón de la Vieja National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 331st most-seen of the 341 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-shouldered Tanager in Rincón de la Vieja 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 White-shouldered 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.

GBIF citizen-science records
It is estimated from how often the White-shouldered Tanager is recorded against all the birds logged in Rincón de la Vieja National Park (6 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.
