Date of this Version
This night-loving and tree-loving, brown tree snake (Boiga irregularis) is so secretive in its nature that it is frequently concealed on container ships and in aircraft cargo. It probably arrived on Guam after World War II in a cargo ship. Now the wetlands, coastlands and forests of Guam are bereft of nine out of twelve native bird species (and two out of eleven native lizards) due to the snakes voracious appetite. The brown tree snake is not a fussy feeder, stimulating the very real fear that it might drive yet more species to extinction.
