The Division of Fish & Wildlife and the Department of Lands and Natural Resources are preparing to introduce two new bird species to the Marianas with the goal of stemming the spread of the brown tree snake, Boiga irregularis.
The brown tree snake has decimated vertebrate species in Guam, especially birds. If the snake were able to establish a population on any of the other islands of the Marianas, it would probably lead to the extinction of several more bird species.
The birds being introduced by the CNMI government are expected to turn the tide of the introduction. Snakes don't eat these birds; these birds eat snakes.
The first bird species is the Tiger Bittern, Gorsakius melanolophus:
The second bird species is the bullfinch, Pyrrhula pyrrhula:
I don't think the brown tree snake stands a chance.
