Wild Boar Hunts Rabbit on Japan's Famous Rabbit Island

Wild boars have been observed preying on healthy rabbits on Okunoshima, an event rarely witnessed and previously thought unlikely. This behavior challenges established views on wild boar diets. Researchers observed a boar capturing and killing a rabbit near a tourist ferry landing in March 2024.

A similar sighting occurred in 2017, indicating a pattern of predation on healthy rabbits. Previously, boars were only known to prey on weakened or deceased rabbits. The presence of humans did not deter the boars, possibly due to increased food availability from tourists.

This human-induced feeding has disrupted natural ecological distances between rabbits and boars. The rabbits, whose population has exploded due to constant feeding, are now severely impacting the island's vegetation, consuming leaves and branches and even damaging toxic plants.

Experts express concern over the fluctuating rabbit population and its environmental consequences. They urge a realistic assessment of the situation to guide future management and conservation efforts for the island's delicate ecosystem.
