Non-native snakes

I recently watched an old Scientific American Frontiers episode about brown tree snakes that were accidentally introduced into Guam in the 1940's (previously, they had no snakes on the island) and the snakes wiped out the native bird population.

Because the snakes are such a problem in places that don't have native snakes (like Hawaii), there are actually snake-sniffing dogs at airports in those countries. They don't use German Shepards like we do in most of the US to sniff bombs or drugs. In Guam, they use terriers and in Hawaii they use Beagles.
