African Wild Dog :: WLR:- Lycaon pictus is a large canid found only in Africa, especially in savannas, lightly wooded areas and along the west African coast. It is variously called the African wild dog, African hunting dog, Cape hunting dog, painted dog, painted wolf, painted hunting dog, spotted dog, or ornate wolf. This dog is the only canine without dewclaws which are the claws that are on the inside of the front feet.
The African wild dog hunts in packs and small groups. Like most members of the dog family, it is a cursorial hunter, meaning that it pursues its prey in a long, open chase. Nearly 80% of all wild dog hunts end in a kill; for comparison, the success rate of lions, often viewed as ultimate predators, is only 30%. Schaller found that 9 of 10 wild dog hunts in the Serengeti ended in kills. Members of a pack vocalize to help coordinate their movements. Its voice is characterized by an unusual chirping or squeaking sound, similar to a bird. Wild dogs frequently kill larger prey via disemboweling, a technique that is rapid but has caused this species to have a negative, ferocious reputation. For this reason, even some early wildlife conservationists, such as Carl Akeley took pride in killing entire wild dog packs.
After a successful hunt, the hunters will regurgitate meat for those that remained at the den during the hunt including the dominant female, the pups, the sick or injured, the old and infirm, and those who stayed back to guard the pups.
The African wild dog's main prey varies among populations but always centers around medium-to-large sized ungulates, such as the impala, Thomson's Gazelle, Springbok, kudu, reedbuck, and wildebeest calves. The most frequent single prey species depends upon season and local availability. For example, in the Serengeti in the 1970s wildebeest (mostly calves) were the most frequently taken species (57%) from January to June, but Thompsons gazelle were the most frequently taken (79%) during the rest of the year. In the Selous Game Reserve, the most frequent prey is impala. While the vast majority of its diet is made up of mammal prey, it sometimes hunts large birds, especially Ostriches. Other predators, such as lions, sometimes steal the prey that wild dogs catch.

Some packs are also able to include large animals among their prey, including zebras and warthogs. The frequency and success rates of hunting zebra and warthogs varies widely among specific packs. To hunt larger prey, wild dogs use a closely coordinated attack, beginning with a rapid charge to stampede the herd. One African wild dog then grabs the victim's tail, while another attacks the upper lip or nose, and the remainder attempt to disembowel the animal. Male wild dogs usually perform the task of grabbing warthogs by the nose. This behaviour is also used on other large dangerous prey, such as the African Buffalo, giraffe calves, and large antelope—even the one-ton Giant Eland.
Studies indicate that this large-animal hunting tactic may be a learned behavior, passed on from generation to generation within specific hunting packs, rather than an instinctive behaviour. Some studies have also shown that other information, such as the location of watering holes, may be passed on similarly.
