⭐ Core Definition: Vultures

A vulture is a bird of prey that scavenges on carrion. There are 23 extant species of vulture (including condors). Old World vultures include 16 living species native to Europe, Africa, and Asia; New World vultures are restricted to North and South America and consist of seven species.A particular characteristic of many vultures is a bald, unfeathered head. This bare skin is thought to keep the head clean when feeding, and also plays an important role in thermoregulation.

Vultures have been observed to hunch their bodies and tuck in their heads in the cold, and open their wings and stretch their necks in the heat. They also urinate on themselves as a means of cooling their bodies.

Vultures in the context of Stele of the Vultures

The Stele of the Vultures is a monument from the Early Dynastic IIIb period (2600–2350 BC) in Mesopotamia celebrating a victory of the city-state of Lagash over its neighbour Umma. It shows various battle and religious scenes and is named after the vultures that can be seen in one of these scenes. The stele was originally carved out of a single slab of limestone, but only seven fragments are known to have survived up to the present day. The fragments were found at Tello (ancient Girsu) in southern Iraq in the 1880s and are now on display in the Louvre. The stele was erected as a monument to the victory of king Eannatum of Lagash over Ush, king of Umma. It is the earliest known war monument.

Vultures in the context of New World vulture

Cathartidae, commonly known as New World vultures and condors, are a family of birds of prey consisting of seven extant species in five genera. It includes five extant vultures and two extant condors found in the Americas. They are known as "New World" vultures to distinguish them from Old World vultures, with which the Cathartidae does not form a single clade despite the two being similar in appearance and behavior as a result of convergent evolution.

Like other vultures, New World vultures are scavengers, having evolved to feed off of the carcasses of dead animals without any notable ill effects. Some species of New World vulture (Cathartes sp.) have a good sense of smell, whereas Old World vultures find carcasses exclusively by sight. Other adaptations shared by both Old and New World vultures include a bald head, devoid of feathers which helps prevent rotting matter from accumulating while feeding, and an extremely disease-resistant digestive system to protect against dangerous pathogens found in decaying meat.

Vultures in the context of Necrophage

Necrophages are animals that feed on decomposing dead animal biomass, such as the muscle and soft tissue of carcasses and corpses (also known as carrion). The term derives from Greek nekros, meaning 'dead', and phagein, meaning 'to eat'. Many hundreds of necrophagous species have been identified including invertebrates in the insect, malacostracan and gastropod classes and vertebrates such as vultures, hyenas, quolls and wolves.

Necrophagous insects are important in forensic science as the presence of some species (e.g. Calliphora vomitoria) in a body, coupled with information on their development stage (e.g. egg, larva, pupa), can yield information on time of death. Information on the insect species present can also be used as evidence that a body has been moved, and analysis of insect tissue can be used as evidence that drugs or other substances were in the body.
