Gurney's Pitta Pitta gurneyi
|
Justification This beautiful pitta is classified as Critically Endangered because it has a tiny, declining population, which occupies a very small, declining range. Its rate of decline is predicted to increase as a result of the continued destruction of its remaining forest habitat, compounded by trapping for the cage-bird trade. However, its recent rediscovery in Myanmar indicates that it is less threatened that previously thought, and further information on the population size and trends in Myanmar may lead to the species being downlisted to a lower category of threat.
Family/Sub-family PITTIDAE

Range & population Pitta gurneyi occurs in peninsular Thailand and adjacent southern Tenasserim, Myanmar. Formerly common across much of its range, there were no field observations in Thailand between 1952 and 1986. Since 1986, intensive surveys have found it in at least five localities, although it has disappeared from all but one of these, Khao Nor Chuchi. This population has declined from 44-45 pairs in 1986 to just nine pairs in 1997, most of which are outside protected-area boundaries. A search for it in Myanmar in 2003 was successful and discovered the species at four sites with a maximum of 10-12 pairs at one location1. Its future is clearly precarious.

Ecology It occurs in secondary, regenerating, lowland semi-evergreen forest, usually below 160 m, with understoreys containing Salacca palms, in which it nests. Territories are centred on gulley systems where moist conditions prevail year-round, usually with access to water, and often close to forest edge. It breeds during the wet season, April-October.
|
|
Threats The key reason for its decline has been the almost total clearance of lowland forest in southern Myanmar and peninsular Thailand through clear-felling for timber, unofficial logging and conversion to croplands, fruit orchards, coffee, rubber and oil-palm plantations. By 1987, only 20-50 km2 of forest below 100 m remained in peninsular Thailand and this area continues to decline. Snare-line trapping for the cage-bird trade is also a serious threat.

Conservation measures underway CITES Appendix I. Following its rediscovery in Thailand, a series of breeding season censuses were conducted, from 1987-1989, to locate and quantify populations in peninsular Thailand. The most important of these, Khao Nor Chuchi, was designated a Non-Hunting Area in 1987, and upgraded to a Wildlife Sanctuary in 1993. The Khao Nor Chuchi Lowland Forest Project was established in 1990 and engaged the local community in participatory management, education programmes and ecotourism, to help reduce pressure on remaining forest. However, this has met with limited success as economic incentives continue to govern land-use decisions. A project in Myanmar aimed at conserving remaining lowland forest in southern Tenasserim will commence in 2004. There are currently no protected areas in this region1.

Conservation measures proposed Conduct comprehensive surveys of remaining populations in southern Myanmar. Extend strict protected area status to all remaining suitable habitat currently outside Khao Nor Chuchi Wildlife Sanctuary boundaries. Establish an in situ protection unit with direct responsibility for safeguarding all remaining habitat, to facilitate cooperation with sanctuary officials and strengthen management and community participation.
