Invasive Species

When the small brown snake entered the U.S. Pacific Island Territory of Guam, there were 13 species of birds, 12 species of lizards and one bat species. What remains is one bat species, three forest birds and six native lizard species. On the other hand there are now one million nocturnal brown snakes even in the smallest areas of Guam. They damage power lines and enter homes through bathroom vents. The small brown snakes belong to the invasive species.
