Suppression of Invasive Brown Treesnakes and Reintroduction of Native Avifauna on Guam.

Many agencies and interest groups are committed to re-establishing components of Guam's native avifauna through the reintroduction of captive-reared birds or translocation from other islands in the Marianas if the Brown Treesnake ( I Boiga irregularis i ; BTS) can be eliminated. The Guam Rail (Gallirallus owstoni), known locally as the Ko'ko', is a ground-dwelling bird that was driven extinct in the wild by Brown Treesnake predation but reintroduced to Cocos Island, adjacent to Guam, from a captive breeding colony. Our simulations indicate that bird persistence in Guam's forests would only be possible at a suppression level just short of full eradication. [Extracted from the article]
