The Hawaii Department of Agriculture is importing four brown tree snakes to be used to train dogs to detect the dangerously invasive species and hopefully prevent the snakes from establishing themselves in the state. Brown tree snakes invaded Guam and nearly wiped out the island's bird species. Hawaii has no native snakes and several species of protected and endangered birds. (AP Photo/Eric Talmadge, File)
