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 →

Rare
Under 5% of wildlife watchers report a Cinereous Vulture sighting in Royal Manas National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 388th most-seen of the 388 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report a Cinereous Vulture in Royal Manas National Park on a given day, against under 5% in March–July and October–January, the lowest months. That is one of Royal Manas National Park's driest months, with about 65 mm of rain against 930 mm in July. August and September have too few records to rate.
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.
12th of 14
Of the 14 parks where we can rate Cinereous Vulture sightings, Royal Manas National Park ranks 12th at under 5%. 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 Royal Manas National Park (family Accipitridae, Hawks, Eagles, and Kites) are Crested Serpent Eagle (about 20%), Mountain Hawk-Eagle (about 20%) and Black 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 Royal Manas National Park (6 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.
