The cinereous vulture (Aegypius monachus), also known as the black vulture, Eurasian black vulture, and monk vulture, is a very large raptor in the family Accipitridae distributed through much of temperate Eurasia. With a body length of 1.2 m (3 ft 11 in), 3.1 m (10 ft) across the wings and a maximum weight of 12.5 kg (28 lb), it is the largest Old World vulture and largest member of the family Accipitridae.
Aegypius monachus is one of the largest birds of prey and it plays an important role in its various ecosystems by eating carcasses, which in turn reduces the spread of diseases. The vultures are constantly exposed to many pathogens because of their eating carrion. A study of the gastric and immune defense systems conducted in 2015 sequenced the bird's entire genome. The study compared cinereous vultures to bald eagles, finding positively selected genetic variations associated with respiration and the ability of the vulture's immune defense responses and gastric acid secretion to digest carcasses.
The genus name Aegypius is a Greek word (αἰγυπιός) for 'vulture', or a bird not unlike one; Aelian describes the aegypius as "halfway between a vulture (gyps) and an eagle... Wikipedia →

With luck
About 10% of wildlife watchers report a Cinereous Vulture sighting in Chitwan National Park on a given day, based on 110 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 155th most-seen of the 367 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February and December
In those months about 20% of wildlife watchers report a Cinereous Vulture in Chitwan National Park on a given day, against under 5% in April to November, the lowest months. Those are among Chitwan National Park's driest months, with about 20 mm of rain a month against 660 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Cinereous Vulture sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 14
Of the 14 parks where we can rate Cinereous Vulture sightings, Chitwan National Park ranks 6th at about 10%. The best odds are in Monfragüe National Park (Spain, about 60%), Gobi Gurvansaikhan National Park (Mongolia, about 40%) and Sierra de Guadarrama National Park (Spain, about 40%). All parks ranked.
Same family: Accipitridae
The closest relatives of the Cinereous Vulture that you can see in Chitwan National Park (family Accipitridae, Hawks, Eagles, and Kites) are Crested Serpent Eagle (about 30%), Oriental Honey-buzzard (about 30%) and Gray-headed Fish-Eagle (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cinereous Vulture is recorded against all the birds logged in Chitwan National Park (110 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.
