Micrurus nigrocinctus
The colors on the snake pulled from the cliff in the film are black bands with white edges, surrounded by large regions of red. Therefore this snake is indeed intended to be a poisonous coral snake (not a king snake), possibly the Central American Coral Snake (Micrurus nigrocinctus), which is found in the Caribbean area. Several other species have the same color pattern, though, and the snake shown in the film appears to have larger regions of red than Micrurus nigrocinctus.

Cotton's bird is a macaw, a specific type a parrot. It has blue wings, a blue head, a green patch on top of its head, and a yellow front, all of which identify it as a Blue and Gold Macaw (Ara ararauna). The book describes the bird as a "parrot" but the film refers to it only as a "bird."

According to the Triva [8-3-06] section on IMDb's page for the first film, Barbossa's monkey is a capuchin monkey. (Actually, two different capuchin monkeys were used for that film.) There are different species of capuchin monkeys. The monkey in the film has a white face and brown fur beyond its facial region, so it could be a White-Fronted Capuchin (Cebus albifrons).
