Visitors Can See New Inhabitants Of Predator Ridge Now, Weather Permitting
Denver, CO - Denver Zoo visitors will notice a couple of new African wild dogs in its Predator Ridge exhibit. The two young sisters, Tilly and Cheza (CHEH-zah) are now exploring the exhibit’s maternity yard after arriving from Chicago’s Brookfield Zoo. Zookeepers say they are settling in well and doing great. Visitors can see them now, weather permitting.
The sisters were born in September 2012 at Brookfield Zoo. Their mother, Kim-ly, was actually born at Denver Zoo in November 2004, making Tilly and Cheza nieces to the Zoo’s pack of older females. Zookeepers do not plan to introduce the sisters to the older pack, though. Instead, they hope to bring in males soon to start a breeding pack. Denver Zoo has been a leader in breeding and managing African wild dogs since the species arrived in 2001. A total of 28 puppies have been born at Denver Zoo since that time.
The largest of Africa’s canine species, full-grown African wild dogs weigh between 40 and 60 pounds and stand 30 inches tall at the shoulder. The slim, long-legged dogs have large, round ears, which not only provide excellent hearing for hunting prey, but also cool them off in the hot African climate. Each African wild dog has its own unique markings of yellow, black, brown and white. Because of this, they are alternately called painted dogs. In fact, their scientific name of Lycaon pictus means “painted wolf-like animal” in Latin.
In addition to their long legs, large lungs provide the dogs with tremendous endurance. They can run at speeds of around 37 miles per hour for more than three miles while pursuing prey. Cooperative pack hunting also increases their success rate, estimated at 70 to 90 percent, and enables them to bring down animals five times their size.
African wild dogs are native to the open woodlands and plains of sub-Saharan Africa. With a wild population estimated at less than 5,000 individuals, African wild dogs are classified as “endangered” by the International Union for Conservation of Nature (IUCN). Their numbers have been reduced by habitat loss, direct persecution and disease. They may contract diseases such as distemper or rabies from domestic dogs. Despite protective laws, wild dogs are still killed by herders to protect domestic livestock.
Denver Zoo conservation biologists also are working to conserve the species in Botswana. Their efforts include studying the species’ range and distribution and building relationships with local ranchers to discourage them from killing the dogs when they venture onto their land.
