Feral animals on Oʻahu

Mongoose and rose-ringed parakeets are established on Oʻahu, along with feral cats, pigs and chickens. Coconut rhinoceros beetles were first found here in 2013; CRB Response says Oʻahu sightings no longer need a report. Axis deer are not established, so a deer sighting is a call.
