Boiga irregularis (Brown catsnake, Brown Tree Snake)


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 island
