The snake was first sighted inland from the seaport and became conspicuous throughout central Guam by the 1960s.By 1968, brown tree snakes had successfully dispersed throughout the island.eason(s) Why it has Become Established: The brown tree snake has become established on Guam due to the absence of natural population controls and the abundance of vulnerable prey on the island.

On Tuesday morning, a pedestrian in Honolulu's Chinatown came across a snake in the sidewalk. Now it'd be surprising enough to stumble upon a two-and-a-half foot non-venomous rainbow boa constrictor at 7 a.m., but in Hawaii it's downright shocking. That's because, technically, Hawaii doesn't have any snakes. While Hawaii is rife with invasive species, snakes are among the most dangerous. Without any natural predators, they compete with the native animal populations for food and habitat, and many snake species prey on birds and their eggs, increasing the threat to Hawaii's many endangered native birds.
