Hawaii’s mule deer records point toward Kauaʻi, with reports near Waimea Canyon and along the wilderness above the Nāpali Coast. Mule deer aren’t native to any Hawaiian island. They’re a western mainland species, and the small number of Hawaii reports most likely reflect escaped or released animals, or possibly misidentification of Hawaii’s more established introduced deer, rather than a wild mule deer population.
On the mainland, mule deer are browsers that favor shrub buds, twigs, and leaves over grass, using huge, independently swiveling ears and a distinctive stiff-legged bounding gait called stotting to cover rough, brushy ground. None of that natural history describes an established Hawaiian population. The species simply doesn’t have a self-sustaining foothold on the islands.
The reported November peak in Hawaii sightings is based on very few records, only about three dozen total, so it’s too thin a sample to represent any real seasonal pattern for this species in the state.
