Three Wild Dog Brothers Set African Mammal Journey Record

Three endangered African wild dog brothers travelled 4,126km across Zambia over eight months, the longest one-way dispersal ever recorded for an African mammal.

Three brothers from the Mayukuyuku Pack in Kafue National Park, western Zambia, set out on their dispersal — the journey young wild dogs must make to leave their family and find unrelated mates. Starting in Kafue and ending in the Luangwa Valley in eastern Zambia, they covered 340 miles point to point, but their total travel distance reached 4,126km (more than 2,500 miles) over eight months. Both The Guardian and Down To Earth report this as the longest single one-way journey ever recorded for any mammal in Africa, beating the previous wild dog record of 2,418 miles set between Tanzania and Kenya in 2012. The brothers appear to have settled in Luangwa and met up with females, no longer dispersing.

Down To Earth reports that seven young dogs — four females and three males — left the same pack within two weeks of each other in 2025 and 2026, all related and so unable to mate with one another. Two months into the journey, the brothers met their sisters deep in Zambia's copper-belt mining region, spending a day together before separating again, and both groups skirted the industrial areas near major cities Kitwe and Ndola. The sisters were far less successful: The Guardian reports two died, probably caught in bushmeat snares, before their final encounter with their siblings. According to Down To Earth, one collared sister later died in a wire snare.

Down To Earth's authors, who have studied African carnivores for 36 years, explain that dispersing dogs shift into a faster, straighter 'travel mode' outside protected areas, resting in thickets and rocky spots to avoid lions, villages and highways. More than half of tracked dispersers did not survive, the outlet reports. The 4,126km figure far exceeds Africa's documented round-trip migrations, such as the blue wildebeest's 650km circuit identified under the UN Convention on Migratory Species.

Both outlets stress that the record journey proves natural connections between Africa's wildlife strongholds still work — Dr Matt Becker of ZCP said the dogs are showing connectivity functions, and now people need to protect and strengthen it. Dr Nyambe Nyambe of the Kavango-Zambezi transfrontier secretariat told The Guardian that conserving connections spanning parks, community areas and nations lets species like wild dogs make the rest happen. Priorities include anti-snaring patrols, support for communities living alongside wildlife, and keeping corridors such as the Luangwa Valley open.
