In 1916, a pack of dogs attacked a private zoo in Hawaii. Two terrified wallabies broke out of their cage and escaped into the mountains.
What happened next is one of the wildest accidents in wildlife history.
After the wallabies vanished into the forested cliffs of Kalihi Valley, the zoo's owner called for a massive public hunt. Nobody caught them.
A local newspaper joked that they might eventually "produce a breed of Hawaiian wallabies."They were exactly right.
Despite being 5,000 miles from Australia, the steep volcanic rock faces in Hawaii turned out to be the perfect habitat.
By 1984, researchers counted roughly 250 wallabies thriving in the valley. They had even started developing their own unique evolutionary characteristics.
The craziest part?
They aren't considered invasive.They only eat non-native plants.
They don't compete with native species (Hawaii has no native land mammals).
Because they peacefully coexist with the ecosystem, the state of Hawaii officially protects them. It is strictly illegal to hunt or harm a Hawaiian wallaby.
Back in their native Australia, the brush-tailed rock wallaby is fighting for its life. Predators, habitat clearing, and the devastating 2019-2020 bushfires wiped out an estimated 70% of their remaining habitat.
But that accidental Honolulu colony?
They have no foxes. No feral cats in the cliffs. No bushfires.
Two wallabies that broke out of a cage 110 years ago accidentally founded what might be the most secure population of their species anywhere on Earth.
