context_page_description: The cinereous vulture is a large raptorial bird that is distributed through much of temperate Eurasia. It is also known as the black vulture, monk vulture, or Eurasian black vulture. It is a member of the family Accipitridae, which also includes many other diurnal raptors such as kites, buzzards and harriers. It is one of the two largest Old World vultures, attaining a maximum size of 14 kg, 1.2 m long and 3.1 m across the wings.
context_section_description: The cinereous vulture measures 98–120 cm (3 ft 3 in–3 ft 11 in) in total length with a 2.5–3.1 m (8 ft 2 in–10 ft 2 in) wingspan. Males can weigh from 6.3 to 11.5 kg (14 to 25 lb), whereas females can weigh from 7.5 to 14 kg (17 to 31 lb). It is thus one of the world's heaviest flying birds. Average weights are not known to have been published for this species but the median weight figures from two sources were 9.42 kg (20.8 lb) and 9.55 kg (21.1 lb). Unlike most accipitrids, males can broadly overlap in size with the females, although not uncommonly the females may be slightly heavier. These are one of the two largest extant Old World vultures and accipitrids, with similar total length and perhaps wingspans recorded in the Himalayan vulture (Gyps himalayensis) , as indicated by broadly similar wing and tail proportions, but the cinereous appears to be slightly heavier as well as slightly larger in tarsus and bill length. Superficially similar but unrelated New World condors can either be of similar wing area and bulk or slightly larger in these aspects.  Despite limited genetic variation in the species, body size increases from west to east based on standard measurements, with the birds from southwest Europe (Spain and south France) averaging about 10% smaller than the vultures from central Asia (Manchuria, Mongolia and northern China). Among standard measurements, the wing chord is 73–89 cm (29–35 in), the tail is 33–41 cm (13–16 in) and the tarsus is 12–14.6 cm (4.7–5.7 in).
  The cinereous vulture is distinctly dark, with the whole body being brown excepting the pale head in adults, which is covered in fine blackish down. This down is absent in the closely related lappet-faced vulture (Torgos tracheliotos). The skin of the head and neck is bluish-gray and a paler whitish color above the eye. The adult has brown eyes, a purplish cere, a blue-gray bill and pale blue-gray legs. The primary quills are often actually black. From a distance, flying birds can easily appear all black. The immature plumage is sepia-brown above, with a much paler underside than in adults. Immature cinereous vultures have grey down on the head, a pale mauve cere and grey legs. The massive bill is the largest of any living accipiterid, a feature enhanced by the relatively small skull of the species. The exposed culmen of the cinereous vulture measures 8–9 cm (3.1–3.5 in). The wings, with serrated leading edges, are held straight or slightly arched in flight and are broad, sometimes referred to as "barn door wings". Their flight is slow and buoyant, with deep, heavy flaps when necessary. The combination of huge size and dark coloration renders the cinereous vulture relatively distinct, especially against smaller raptors such as eagles or buzzards. The most similar-shaped species, the lappet-faced vulture (with which there might be limited range overlap in the southern Middle East), is distinguished by its bare, pinkish head and contrasting plumage. On the lappet-face, the thighs and belly are whitish in adult birds against black to brownish over the remainder of the plumage. All potential Gyps vultures are distinguished by having paler, often streaky plumage, with bulging wing primaries giving them a less evenly broad-winged form. Cinereous vultures are generally very silent, with a few querulous mewing, roaring or guttural cries solely between adults and their offspring at the nest site.
