Wikipedia Abstract

The brown tree snake (Boiga irregularis) is an arboreal rear-fanged colubrid snake native to eastern and northern coastal Australia, eastern Indonesia (Sulawesi to Papua), Papua New Guinea, and a large number of islands in northwestern Melanesia. This snake is infamous for being an invasive species responsible for devastating the majority of the native bird population in Guam.

Invasive Species

Native island species are predisposed and vulnerable to local extinction by invaders. When the brown tree snake (Boiga irregularis) was accidentally introduced to Guam it caused the local extinction of most of the islandís native bird and lizard species. It also caused "cascading" ecological effects by removing native pollinators, causing the subsequent decline of native plant species. The ecosystem fragility of other Pacific islands to which cargo flows from Guam has made the potential spread of the brown tree snake from Guam a major concern.
