VU Black-billed Amazon  Amazona agilis

2009 IUCN Red List Category (as evaluated by BirdLife International - the official Red List Authority for birds for IUCN): Vulnerable

Justification The extent of this species's range is very small, but it does not qualify as Endangered because habitat is not severely fragmented and it is known from more than five locations. Habitat is declining in extent, area and quality, and further population reductions are being caused by trapping and predation, qualifying the species as Vulnerable.

Family/Sub-family Psittacidae

Species name author (Linnaeus, 1758)

Range & population Amazona agilis is fairly common in the centre of Jamaica, from Cockpit Country to Mount Diablo1,5. It also occurs on the eastern slopes of the John Crow Mountains1. The population in Cockpit Country was previously thought to number fewer than 10,000 individuals, however recent surveys estimate 7,500 - 9,500 territorial pairs are present and the species is fairly common there; but it is much less common on Mt. Diablo1,7,8.

Ecology: This parrot occurs primarily in wet limestone forests and forest edge, mostly at elevations of 100-1,400 m 1,2,5. It also uses cultivated land and plantations adjacent to forest for foraging1. Pairs and flocks feed high in the canopy on fruits, blossoms, nuts and seeds6. Breeding takes place from March to August1. The use of abandoned Jamaican Woodpecker Melanerpes radiolatus cavities has been reported6, but the majority of pairs use tree-hollows that form from processes related to weathering or pathogen and insect attacks4.

Threats Shifting cultivation, logging and bauxite mining have reduced suitable habitat, and the species is trapped for local consumption1,5. Bauxite mining licenses were recently issued for over 60% of the Cockpit Country Conservation Area, which supports over 90% of the global population of this species9. A population Viability Analysis indicated that were mining to take place as planned this species might decline by 50% over the next 15 years9. Predation by yellow boa Epicrates subflavus is a significant limiting factor to nesting success: of the 26 nest-sites located during the 1997 breeding season, over 30% suffered total failure and another 6% partial mortality during the early nesting stage3. There is no evidence that poaching for the cage-bird trade has a major impact3. There is a risk of hybridisation with other species of imported Amazona8.

Conservation measures underway CITES Appendix II. Since 1995, there has been work to delineate its range, estimate population size, identify factors limiting reproductive performance and train local people in research methods and techniques for long-term monitoring1,3. Habitat in the Blue and John Crow Mountains has been declared a national park, but enforcement and management are weak1. There is an on-going, high profile public awareness campaign to prevent bauxite mining in Cockpit Country by having the area declared "closed to mining" Minister's Discretion8. Discussions have been initiated which may lead to the banning of the importation of psittacines to Jamaica, to lower the risk of escapes and hybridisation8.

Conservation measures proposed Survey to delineate range and assess numbers1. Establish a long-term monitoring programme. Designate Cockpit Country "closed to mining". Ensure de facto protection of the national park in the Blue and John Crow Mountains1. Design and implement education programmes in and adjacent to the species's occupied range1.
