Illegal Aliens in Hawai‘i

The Green Iguana is native to Mexico, Central and South America. First seen in the late 1950s, it is established on O‘ahu and commonly found in the Manoa, Nu'uanu and Waimanalo Valleys. The iguana feeds on brightly colored flowers, leaves and fruits of many plants. It has along tail and ranges in size from three to five feet. It is not aggressive but will bite and scratch if captured.

Snakes are a favorite pet to smuggle into the state. They are increasingly being found in the wild as escaped pets or animals released by their owners. 1992 was a record year for snake finds; 38 snakes (dead and alive) were found! An established population of any snake could spell disaster for native birds and the local poultry business.

Caimans and alligators have been temporary residents on O‘ahu. In 1983 two caimans, a South American cousin of the American Alligator, were found in Nu'uanu Reservoir. In 1991 the bodies of two alligators were found in Kailua. The first was discovered in Maunawili Stream in April and measured six feet. The other, over five feet in length, was found along the Kapa'a Quarry Road four months later.
