The bare-necked fruitcrow (Gymnoderus foetidus) is a species of bird in the family Cotingidae, the cotingas. It is found in every mainland South American country except Argentina, Chile, Uruguay, and Paraguay. The bare-necked fruitcrow was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under the binomial name Gracula foetida. Linnaeus specified the type locality as America but in 1902 the locality was restricted to Surinam. The bare-necked fruitcrow is now the only species placed in the genus Gymnoderus that was introduced in 1809 by the French naturalist Étienne Geoffroy Saint-Hilaire. The genus name combines the Ancient Greek gumnos meaning "bare" or "naked" with dera meaning "neck" or "throat". The specific epithet foetidus is Latin meaning "stinking". The species is monotypic: no subspecies are recognized.
A large molecular phylogenetic study of the suboscines published in 2020 found that the bare-necked fruitcrow was sister to the black-faced cotinga (Conioptilon mcilhennyi). The bare-necked fruitcrow is 34 to 39 cm (13 to 15 in) long; one individual weighed 220 g (7... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bare-necked Fruitcrow is recorded against all the birds logged in Anavilhanas National Park (46 verified sightings from 2019 to 2026), calibrated against known sighting rates.
