The chestnut-headed tanager (Thlypopsis pyrrhocoma) is a species of bird in the tanager family Thraupidae. It is found in the Atlantic Forest of southeast Brazil, eastern Paraguay, and far northeastern Argentina. It was formerly the only member of the genus Pyrrhocoma but is now placed in Thlypopsis.
The chestnut-headed tanager was formally described in 1844 by the English naturalist Hugh Edwin Strickland under the binomial name Tachyphonus ruficeps. The species was subsequently placed in the monotypic genus Pyrrhocoma by the German ornithologist Jean Cabanis. A molecular phylogenetic study published in 2014 found that the chestnut-headed tanager was embedded in a clade containing members of the genus Thlypopsis. The genera were therefore merged but as Thlypopsis already contained the rust-and-yellow tanager as Thlypopsis ruficeps d'Orbigny & Lafresnaye, 1837, a new specific epithet pyrrhocoma was coined for the chestnut-headed tanager, using the earlier generic name "to communicate past taxonomic connections". The name comes from the Ancient Greek purrhokomēs meaning "red-haired". The species is monotypic: no subspecies are recognised.

Rare
Under 5% of wildlife watchers report a Chestnut-headed Tanager sighting in Curitiba on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 209th most-seen of the 247 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
In that month about 10% of wildlife watchers report a Chestnut-headed Tanager in Curitiba on a given day, against under 5% in July to May, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Chestnut-headed 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 Curitiba, in our data
Curitiba is the only city on Wallace's Line with enough records to rate Chestnut-headed 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 Chestnut-headed Tanager is recorded against all the birds logged in Curitiba (11 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.
