Q
…vultures came to mind, so I DuckDuckGo'd and found the following:

…though this is interesting, too:

A vulture is a scavenging bird of prey. The two types of vultures are the New World vultures, including the Californian and Andean condors, and the Old World vultures, including the birds that are seen scavenging on carcasses of dead animals on African plains. Some traditional Old World vultures (including the bearded vulture) are not closely related to the others, which is why the vultures are to be subdivided into three taxa rather than two. New World vultures are found in North and South America; Old World vultures are found in Europe, Africa, and Asia, meaning that between the two groups, vultures are found on every continent except Australia and Antarctica (though Trigonoceps vultures have crossed the Wallacea] line).[2]
A particular characteristic of many vultures is a bald head, devoid of normal feathers. Although it has been historically believed to help keep the head clean when feeding, the bare skin may play an important role in thermoregulation.[3] 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. Vultures also use urine as a way to keep themselves cool by urinating on themselves.[4]
A group of vultures is called a kettle, committee or wake.[5] The term kettle refers to vultures in flight, while committee refers to vultures resting on the ground or in trees.[5] Wake is reserved for a group of vultures that are feeding.[5] The word Geier (taken from the German language) does not have a precise meaning in ornithology; it is occasionally used to refer to a vulture in English, as in some poetry.

New World vultures
Main article: New World vulture
The New World vultures and condors found in warm and temperate areas of the Americas are not closely related to the similar Accipitridae, but belong in the family Cathartidae, which was once considered to be related to the storks. However, recent DNA evidence suggests that they should be included among the Accipitriformes, along with other birds of prey. However, they are still not closely related to the other vultures. Several species have a good sense of smell, unusual for raptors, and are able to smell dead animals from great heights, up to a mile away.
The seven species are:
Black vulture Coragyps atratus in South America and north to the US
Turkey vulture Cathartes aura throughout the Americas to southern Canada
Lesser yellow-headed vulture Cathartes burrovianus in South America and north to Mexico
Greater yellow-headed vulture Cathartes melambrotus in the Amazon Basin of tropical South America
California condor Gymnogyps californianus in California, formerly widespread in the mountains of western North America
Andean condor Vultur gryphus in the Andes
King vulture Sarcoramphus papa from southern Mexico to northern Argentina
