Three brothers, one epic journey: wild dogs cross Zambia in record 2,500-mile trek

Scientists have recorded the longest known journey by African wild dogs: a 2,500-mile (4,000-kilometer) trek across Zambia by three brothers in search of a mate. The brothers traveled through unfamiliar territory, crossing rivers and dodging threats such as lions, snares, and vehicles. Researchers say the record-breaking journey shows the animals can survive growing pressures on their habitat, including shrinking space and human conflict. African wild dogs are endangered. Fewer than 7,000 remain in the wild, and packs need large areas to hunt and breed. The study's authors say the finding offers hope: if the dogs can move across such distances, they may be able to reach new areas and find mates, helping the species survive.
