The red-necked tanager (Tangara cyanocephala) is a species of bird in the family Thraupidae. It is found in Brazil, Argentina, and Paraguay. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest.
The red-necked tanager was first described by Philipp Müller in 1776 as Tanagra cyanocephala. It is mostly green with a black back and a blue head and throat. Plumage is described as "brilliant and varied, including areas of bright red, bright green, blue, and black." They can be observed in mixed-species flocks along with green-headed tanagers.

GBIF citizen-science records
It is estimated from how often the Red-necked Tanager is recorded against all the birds logged in Santos (92 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.
