Scavenging is their specialty and vultures are extraordinary scavengers. The vulture has keen eyesight and excellant sense of smell. This aids in finding dead critters to dine on. Vultures are fairly heavy birds, which is useful in chasing other scavengers such as coyotes or jackals away from a carrion feast. Various species of vulture possess different characteristics designed for the food they eat. For example, some vultures have super strong bills, the better to rip tendons and sinew off a carcass. Other vultures have long necks that make it convenient to reach deep inside of a dead animal and pluck out some tasty innards. Still other vultures eat the bones of an animal. Large bones are dropped from great heights to break them up for easier swallowing. These birds have amazingly strong stomach acids to do the digesting.
Most Vultures eat dead things. However, some eat insects and the inside material of eggs. To crack a small egg, the bird will pick it up and drop it. If it is a larger egg, the vulture will repeatedly drop a stone on the egg to crack the shell.
Vultures rarely flap their wings and are able stay aloft on wind currents for hours. Many vultures gather in groups to rest, as well as while soaring. Some vultures work together with other (vulture) species to find dead stuff to eat. They then share the find.

What is the difference between a Vulture and a Condor? And where does the Buzzard fit in?
Most vultures from Europe, Africa and Asia are decended from birds of prey such as eagles. Those found in the Americas are from the same line of ancestry as storks. These similar birds coming from separate roots are considered examples of divergant evolution. The difference between a vulture and a condor appears to be a secret known only to experts.
As for buzzards: that is a charming colloquial term for condors and vultures originating from the USA.
