Three Wild Dog Brothers Set Record with 2,500-Mile Journey Across Zambia

Three endangered African wild dog brothers have completed the longest single journey ever recorded for an African mammal, traveling more than 2,500 miles across Zambia over an eight-month period.

Scientists monitored the siblings during their "dispersal," a phase when young animals leave their original pack to search for new territory, find mates, and establish their own family units. The dogs began their trek in Kafue National Park in western Zambia and ultimately reached the Luangwa Valley in the east. The direct point-to-point distance between these two locations spans 340 miles (546 km), setting a new regional distance record.

Navigating Human Landscapes and Threats

Researchers from the Zambian Carnivore Programme (ZCP) tracked the pack and published their findings in the journal Ecology. Throughout their eight-month trek, the brothers navigated multiple hazards, including roads, hunters, and bushmeat snares across human-dominated terrain.

The previous distance record for African wild dogs was set in 2012, when another group covered 2,418 miles between northern Tanzania and southern Kenya. The ZCP monitored 19 separate groups of wild dogs during the study, including a female group related to the three brothers. Two months into the journey, the brothers briefly reunited with their sisters in Zambia's Copperbelt mining region, spending a day together before separating. The sisters were less fortunate; two later died, likely after becoming trapped in wire snares.

Implications for Wildlife Connectivity

Dr. Matt Becker, chief executive of the ZCP, noted that while the record-breaking journey demonstrates that natural wildlife corridors still function, it also highlights the growing dangers animals face moving through fragmented environments. Becker advocated for continuous investment in connected landscapes across protected zones rather than relying solely on fenced wildlife reserves.

African wild dogs are listed as endangered on the International Union for Conservation of Nature (IUCN) Red List, with approximately 6,600 adults remaining across 39 distinct populations. The species faces major threats from habitat loss, prey decline, wire snares, and conflict with humans.

Dr. Nyambe Nyambe, director of the Kavango-Zambezi transfrontier area secretariat, emphasized that conserving cross-border wildlife corridors spanning national parks and community areas remains essential for enabling species like wild dogs to relocate and maintain healthy populations.
