Alien snake research. Biologist Earl Campbell suspends a captured brown tree snake (Boiga irreg- ularis) on a scale while taking its weight. The alien snake will be sexed, measured, tagged, then released back into the wild. Campbell is resident herpetologist on Guam Island in the Pacific, undertaking a study on the ecology of Boiga irreg- ularis. It is hoped the study will help scientists control the snake. Introduced to Guam half a century ago, this bird-eating venomous snake has become a pest. The island hosts over a million of these reptiles. Native bird species have been eradicated, children bitten, while the snake threatens to spread to other islands.
