Oftentimes, scavenger communities differ in consistency due to carcass size and carcass types, as well as by seasonal effects as consequence of differing invertebrate and microbial activity. [4] Competition for carrion results in the inclusion or exclusion of certain scavengers from access to carrion, shaping the scavenger community.
The black vulture is a fairly large scavenger, measuring 56–74 cm (22–29 in) in length, with a 1.33–1.67 m (52–66 in) wingspan. [30] Weight for black vultures from North America and the Andes ranges from 1.6 to 3 kg (3.5 to 6.6 lb) but in the smaller vultures of the tropical lowlands it is 1.18–1.94 kg (2.6–4.3 lb).
The turkey vulture is a scavenger and feeds almost exclusively on carrion. [3] It finds its food using its keen eyes and sense of smell, flying low enough to detect the gasses produced by the early stages of decay in dead animals. [3] In flight, it uses thermals to move through the air, flapping its wings infrequently. It roosts in large ...
Holtz also pointed out that felids also developed thickened teeth as adaptations to resist contact with bone during prey capture or dispatch as well as during feeding. [21] Since at least some of Tyrannosaurus ' s potential prey could move quickly, evidence that it walked instead of ran could indicate that it was a scavenger.
Cathartiformes, also known as New World vultures, possess unique adaptations in their plumulaceous feathers that prevent the accumulation of bacteria and fungal spores, allowing them to feed on carrion without getting sick. These feather adaptations include a lack of aftershaft, a flattened shape, and a porous structure that allows air to flow ...

The marabou stork is a frequent scavenger, and the naked head and long neck are adaptations to this livelihood, as it is with the vultures with which the stork often feeds. In both cases, a feathered head would become rapidly clotted with blood and other substances when the bird's head was inside a large corpse, and the bare head is easier to ...
The Andean condor is a scavenger, feeding mainly on carrion. [39] Wild condors inhabit large territories, often traveling more than 200 km (120 mi) a day in search of carrion. [25] In inland areas, they prefer large carcasses.
