Brown tree snakes apparently got to Guam during World War II, hitching rides on military vehicles or some other part of the high-level traffic at the island during that conflict. In the ensuing years, they have wiped out several species of native Guam birds and almost destroyed many others.
Should the slithery genocidists manage to hitch another ride, they might spread to other islands where birds don't know how to handle a nocturnal, tree-dwelling predator.

As it happens, another feature of brown tree snakes is that the acetaminophen found in
