Javan Trogon Apalharpactes reinwardtii
BirdLife Species Champion Become a BirdLife Preventing Extinctions Programme Supporter
For information about BirdLife Species Champions and Species Guardians visit the BirdLife Preventing Extinctions Programme.

Justification
This species is classified as Endangered because it has a very small population which is likely to be in decline owing to habitat loss and degradation.

Taxonomic note
Harpactes reinwardtii (Sibley and Monroe 1990, 1993) has been split (and generic attribution revised) into Apalharpactes reinwardtii and A. mackloti following Collar and van Balen (2002).

Identification
34 cm. A striking green and yellow trogon. Upperparts green, except for a blue tail. Underparts largely yellow with a green breast band. The bill is red and the naked skin around the eye is blue. Voice A dry, high rattling "sterrrr".

Distribution and population
Apalharpactes reinwardtii is known from just six forested mountains in West Java, Indonesia: Gunung Halimun, Gunung Salak, Gunung Gede-Pangrango, Gunung Patuha-Tilu, Gunung Wayang and Gunung Papandayan. There are only recent records from three of these (Halimun, Salak and Gede-Pangrango). The historical range totals 11,600 km2. Although it has been stated to occur from 800-2,600 m, little forest remains below 1,000 m away from Halimun, and the species appears to be rarer at higher elevations. The only site where the species appears to be common now is Gunung Halimun, but only at lower elevations. The population size of this species may be as low as a few hundred pairs (Collar and van Balen 2002).

Population justification
The population size has been estimated to be as low as a few hundred pairs. It is thus placed in the band 250-999 mature individuals, equating to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.

Trend justification
Although much of the population may now be restricted to two protected areas on Java, it is suspected to be continuing to decline at a moderate rate, owing to the on-going encroachment of forests by agriculture and urban development.

Ecology
It appears to favour mid-montane forest, where it feeds on a variety of invertebrates taken by aerial sallying or by perch-gleaning. It also feeds on fruit and will occasionally join mixed-species flocks (del Hoyo et al. 2001).

Threats
Forest loss, degradation and fragmentation, through widespread agricultural encroachment and localised development (e.g. holiday resorts and geothermal projects), are increasing threats in the species's altitudinal range.

Conservation Actions Underway
The species has been recorded in Gunung Halimun and Gunung Gede-Pangrango National Parks. Conservation Actions Proposed
Conduct further surveys for the species at all mountains potentially within its range to clarify its current distribution and population status. Propose key sites for designation as protected areas, or as extensions to existing reserves. Work with local authorities and relevant companies to minimise the impact of tourism and development projects on forested mountains within its range.
