The Puerto Rican parrot is one of the ten most endangered birds in the world, with the only wild population comprised of 30-40 birds. Predation has been identified as one of the factors limiting Puerto Rican parrot productivity in the wild, and the loss of a very few birds can have a great impact on the species. Management of red-tailed hawks, and black rats, feral cats and Indian mongooses, as well as further management of pearly-eyed thrashers is potentially beneficial to the parrot population. Because funding for the recovery of this rare species is finite, an analytical examination of the economics of predator management as a species enhancement method can provide managers with a solid basis for justifying and implementing this management approach.
