Three wild dog brothers trek 2,500 miles across Zambia in record mammal journey

Three brother African wild dogs travelled more than 2,500 miles over eight months from Kafue National Park to Luangwa Valley in Zambia in search of territory and mates. Researchers from the Zambian Carnivore Programme called it the longest-ever recorded single journey of any mammal from Africa. About 6,600 adults remain; the species is endangered.
