| dc.description | A preliminary survey for Gurneyʼs Pitta Pitta gurneyi was undertaken at five sites within the speciesʼ historical range in the Tanintharyi (Tenasserim) Division of Myanmar from 14 to 24 May 2003. During the surveys, Gurneyʼs Pittas were heard and/or observed at four sites with a maximum of 10–12 pairs recorded at one site. Birds were encountered in logged primary and secondary forest below 100 m on flat ground, sometimes less than 10 m from forest edge. All encounters were within 2 km of the main trans-Tanintharyi highway. Landsat satellite imagery was used to map remaining lowland forests and Gurneyʼs Pitta habitat in the Tanintharyi Division. Our analysis demonstrated that only 4,705 km<sup>2</sup> of lowland forest remain with about 3,496 km<sup>2</sup> in flat areas with slopes < 10°. On the basis of previously reported population densities, these habitats may support a population of 5,152–8,586 pairs. Much of the remaining habitat is restricted to small and fragmented patches < 1 km<sup>2</sup> in area. The five largest patches have a total area of 1,431 km<sup>2</sup> and range in size from 137 to 467 km<sup>2</sup>. This survey demonstrated that Gurneyʼs Pitta still occurs within its historical range in Myanmar, although probably not at any of the historical collecting localities visited. The global population of Gurneyʼs Pitta is at least 100% greater than the latest published estimate. This survey has also shown that the Gurneyʼs Pitta population in southern Tanintharyi Division is under pressure from forest conversion to oil palm. Contrary to the situation in neighbouring Thailand, sufficient forest remains to establish landscape level protected areas covering a broad ecological continuum. Securing populations of Gurneyʼs Pitta within either expanded or entirely new protected areas must be the best chance for the species and the Sundaic flora and fauna of which it is part. |
