It is in the bosques húmedos de piedra caliza to elevations of 1.600 m. They can be seen in the upper canopy, and they can also be found foraging in cultivated land and plantations near the edge of the forest.
Form groups 6 a 30 individuals.
Reproduction:
The Black-billed Parrot used for nest the tree holes are formed from or related to weathering processes and pathogen attacks insects, at least a 18 meters above the ground. It has reported the use of cavity left by the Jamaican Woodpecker (Melanerpes radiolatus).
Like other species of parrots, the vigorous vocalizations among couples announce nesting territories.
The breeding season It is from March to August. The laying is of 2-4 eggs, with a range of about 48 hours between successive eggs. Eggs are incubated únicamente por la hembra durante 24 days. During this time the male will feed and exchange food with female. The incubation It begins after the first egg is placed, so hatching occurs at intervals, con hasta siete días entre la primera y última eclosión. Chicks this amazon They spend up to eight weeks in the nest.
La mayoría de los nidos fracasados lo hacen en el período de apareamiento temprano, as a result of predation by Jamaican Boa (Epicrates subflavus) (Gruber 1980) and to a lesser extent Jamaican Crow (Corvus jamaicensis).
Food:
The Black-billed Parrot It feeds on fruit, seeds, dried fruits, berries and flowers in the forest canopy. The populations of this species will move in response to the location of food sources. This species also feed on crops and can cause considerable damage to fruit ripening.
Distribución y estatus:
Size of its range (breeding/resident): 5.100 km2
Its distribution area está restringida a los bosques de calizas húmedas de nivel medio, que se han reducido drásticamente en los últimos 40 years. Locally common by all the Cockpit Country, particularmente en el hábitat perturbado del borde donde es más común que la Yellow-billed Parrot (Amazona collaria), with which occasionally is associated.
The populations of the Black-billed Parrot also they found in Mount Diablo, in the center of the island. Historical reports also placed at the eastern end of the island, although recent sightings in that area are rare. However, small flocks have been recently in the John Crow Mountains. Preliminary surveys indicate population estimates much higher than those described above, and possibly more than 10.000 individuals in the region of Cockpit Country (C. Levy in some 1999).

• Current category of the Red List of the UICN: Vulnerable.
• Population trend: Decreasing.
• Population size : 6000-15000
Rationale for the Red List category
This species has a range very small within which its habitat is declining in extent, area and quality; and additional reductions of the population are being caused by the trampeo and predation, qualifying the species as Vulnerable. Currently it does not qualify as endangered because the habitat is severely fragmented and is known in more than five places. However, the species can requalify for inclusion in a top list in the future due to population decline likely if the three proposed mining concessions Cockpit Country They are awarded.
Justification of the population
Las estimaciones preliminares de población son las que mejor sitúan a la población mundial en la banda entre 10.000 and 19.999 individuals (S. Koenig in a bit., 2008). This is equivalent to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals. Further studies are needed to get an accurate figure.
Justification of trend
The data suggest that decrease of at least 50% de la población de esta especie podría ocurrir en los próximos 40-50 years as a result of habitat destruction due to three proposed mining concessions, two of which have recently been granted (Koenig, 2008). However, It is not sure if the third concession is granted (S. Koenig in some. 2010), and as such it is projected to suffer a decrease of species 30-49% over the next 37 years (three generations).
