African wild dog: A profile on Africa’s most successful hunters

African wild dogs, also known as painted wolves or cape hunting dogs, are native to sub-Saharan Africa. They are the only living species in the Lycaon genus. Distinguished from the genus Canis, which includes wolves and dogs, by their lack of a dew claw and a hypercarnivorous diet. These unique creatures are currently endangered, with an estimated wild population of approximately 6,600 individuals, according to the IUCN.

Distinctive Characteristics and Social Behaviour

Boasting a diverse coat pattern, each African wild dog exhibits a unique design. Recognizable by large yellow and white splotches on dark fur and distinctive satellite-shaped ears, these lean and tall animals are built for endurance running.

Weighing between 20-25 kg they are about twice the size of a black backed jackal. They typically form highly social groups of 2 to 27 individuals, although larger aggregations in their hundreds have formed in times of seasonal migrations of prey animals.

Reproductive Strategies and Evolutionary Advantages

Female African wild dogs produce the largest litters among canids, ranging from 6 to 16 pups. However, only dominant pairs are allowed to reproduce, as they ruthlessly enforce the prohibition on sub-dominant pairs. This behaviour offers an evolutionary advantage by ensuring that only the strongest and smartest individuals, that rise to the top of the hierarchy, pass on their genes.

Impact of Female Migration on Breeding Ratios

The migratory habits of females has had a curious influence on the breeding sex ratios within wild dog packs. In the first litters of young females, there is a higher proportion of male pups. This is attributed to the fact that a newly formed pack with a young dominant female tends to produce consistent hunters for the pack, as males typically stay with their natal packs throughout their lives.

As females mature, their litters become more female-dominated. This occurs because most females migrate to other packs or establish their own. The higher proportion of females in the litter prevents the pack size from becoming excessively large and ensuring a consistent population.

Hunting Strategies and Success Rates

African wild dogs demonstrate remarkable hunting prowess, boasting success rates ranging from 60% to 90%, outperforming cheetahs (55%) and lions (25%). This exceptional success results from a combination of physical prowess and intelligent hunting strategies.

Operating in a coordinated pack, these dogs silently approach their prey. Upon alerting the prey, the pack collaboratively pursues a single individual, utilizing their impressive speed of 44 mph (equivalent to a greyhound) and remarkable endurance to exhaust the target. As they chase their prey, they deliver repeated bites to the prey’s hind legs until it is subdued.

These hunts cover extensive distances, reaching up to 2 km, and once successful, the entire pack efficiently consumes the prey in under 15 minutes. This rapid consumption not only maximizes hunting efficiency but also minimizes the risk of losing the kill to larger predators.

Although the East African wild dog focuses mainly on hunting Thomson’s Gazelles, hunting dogs across Africa have adapted their hunting strategy to suit their target with some targeting warthogs and even reports of wild dogs bringing down fully grown Zebra.

Conservation Challenges and Threats

Estimates suggest around 111 wild dogs inhabit Tsavo’s conservation area and only 865 in the country. These wild canines already face many natural challenges from other large carnivores in their area. Battling to retain kills from lions and spotted hyenas.

Beyond this there is also the risk of disease spread from domestic dog populations that can have detrimental effects on wild dog populations. This occurred in 1991 in the Maasai Mara where the majority of the wild dogs were lost with populations struggling to recover in the area.

There is also concerns over the impacts of climate change on the hunting ability of wild dogs. As the dogs are diurnal hunters, with most action taking place in the cool hours of the morning and evening scientists are concerned that rising temperatures will reduce the amount of hours the wild dogs are able to hunt.

Hope for the Future: Conservation Efforts

The Kenya Rangelands African Wild Dog and Cheetah Project has undertaken a comprehensive approach to ensure the survival of African wild dogs.

Initiatives include vaccinating domestic livestock against rabies, educating pastoralists on efficient livestock pens, and encouraging traditional land use practices.

The success of these efforts is exemplified by an eight-fold increase in the wild dog population in the Samburu-Laikipia region over the past decade.

A Glimpse into the Past and Future

As we marvel at the remarkable adaptations and strategies of African wild dogs, their conservation becomes paramount. Understanding their behaviour, challenges, and the success of conservation initiatives provides valuable insights for preserving these fascinating creatures in the face of contemporary threats. The ongoing research and dedication of conservation projects offer hope for a future where African wild dogs can thrive in their natural habitats.
