In a remarkable feat of survival that researchers have likened to a cinematic odyssey, three African wild dog brothers successfully completed the longest single journey ever recorded for the species. After leaving their natal pack in western Zambia’s Kafue National Park, the siblings navigated a perilous 2,500-mile (4,100km) route over the course of eight months. Their journey, which concluded in the Luangwa Valley in the east of the country, represents a point-to-point distance of 340 miles (546km), setting a new record for African wild dog dispersal.
This migration, which occurred last year, saw the brothers navigate through human-dominated landscapes, dodging traffic, hunters, and bushmeat snares. Their trek is comparable to walking the entire length of Chile and exceeds the scale of the famous Serengeti migrations undertaken by wildebeest and zebra. The previous record for such a journey was established in 2012, when African wild dogs traveled 2,418 miles between Tanzania and Kenya.
Dr. Matt Becker, chief executive of the Zambian Carnivore Programme (ZCP), noted that the findings, published in the journal Ecology, demonstrate that natural connections between wildlife strongholds remain intact. However, he emphasized that these routes are becoming increasingly dangerous. According to Becker, the success of the brothers reinforces the necessity of investing in connected landscapes rather than relying exclusively on fenced-in protected zones. He stressed that connectivity remains a functional survival strategy for wildlife, provided it is protected and strengthened.
The study involved monitoring 19 separate groups of wild dogs, including a group of sisters related to the three brothers. The sisters were less fortunate; two died during their dispersal, likely due to snares, though they did share a brief, final encounter with their brothers before their deaths. With only approximately 6,600 adult African wild dogs remaining across 39 distinct populations, the species is currently classified as endangered on the International Union for Conservation of Nature’s red list. They face constant threats from habitat loss, human conflict, and a decline in natural prey.
Despite these significant challenges, the survival of the three brothers serves as a testament to the resilience of the species. Dr. Nyambe Nyambe, director of the Kavango-Zambezi transfrontier area secretariat, highlighted the importance of maintaining transboundary corridors across the five countries in the region. He stated that if these connections between national parks and community areas are preserved and improved, species like the African wild dog can continue to navigate and thrive across the landscape.
It sounds like a Disney movie: three wild dogs, all brothers, on an epic journey to find a home of their own after their family tells them to leave. They dodge cars and hunters in search of a new life, navigating bushmeat snares and the hostility of a human-dominated landscape until they find a new haven on the African savannah.
But researchers say the three brothers’ epic journey shows the wild dogs can still survive in a human-dominated landscape despite the enormous challenges they face. Alongside African savannah elephants, whose ancient migration routes are increasingly being blocked by human development, African wild dogs need to be able to make long journeys to find new homes.
