Boiga irregularis or brown snake is a slender, climbing snake with a vertical pupil and large eyes, providing it better nocturnal vision. The species has no natural predator. When the brown snake is accidentally released into the island, it will result in local extinction of the majority of the island's native lizard and bird species.
It will also result in cascading ecological influences by eradicating native pollinators, resulting in the corresponding reduction of the native plant species.
Hence, the correct answer will be fewer birds and more snakes.
