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 →

Rare
Under 5% of wildlife watchers report a Bare-necked Fruitcrow sighting in Sierra de la Macarena National Park on a given day, based on 21 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 263rd most-seen of the 418 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.
March–April and September
In those months about 10% of wildlife watchers report a Bare-necked Fruitcrow in Sierra de la Macarena National Park on a given day, against under 5% in May–August and October–February, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Bare-necked Fruitcrow sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 7
Of the 7 parks where we can rate Bare-necked Fruitcrow sightings, Sierra de la Macarena National Park ranks 7th at under 5%. The best odds are in Cuyabeno Wildlife Reserve (Ecuador, about 30%), Yasuní National Park (Ecuador, about 20%) and Amacayacu National Natural Park (Colombia, about 10%).
Same family: Cotingidae
The closest relatives of the Bare-necked Fruitcrow that you can see in Sierra de la Macarena National Park (family Cotingidae, Cotingas) are White-winged Becard (about 20%), Guianan Cock-of-the-rock (about 10%) and Black-tailed Tityra (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bare-necked Fruitcrow is recorded against all the birds logged in Sierra de la Macarena National Park (21 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.
