 Natural predators of the Puerto Rican amazon include the red-tailed hawk (Buteo jamaicensis), the broad-winged hawk (Buteo platypterus), the peregrine falcon (Falco peregrinus) and the pearly-eyed thrasher (Margarops fuscatus). The thrasher invaded Puerto Rico in the mid-20th century and has been a problem for the parrot population since 1973; to combat this, specially designed deep nests were prepared for the parrots in subsequent years to prevent competition from the invaders. Introduced honeybees (Apis mellifera), the related Hispaniolan amazon (Amazona ventralis), black rats (Rattus rattus) and Indian mongooses (Herpestes javanicus) may compete for nesting cavities, and the latter two may eat eggs and chicks.
