Overview

Distribution

Range Description

Apalharpactes reinwardtii is known from seven forested mountains in West Java, Indonesia: Gunung Halimun, Gunung Salak, Gunung Gede-Pangrango, Gunung Patuha-Tilu, Gunung Wayang, Gunung Papandayan and Ciwidey. There are only recent records from four of these (Halimun, Salak, Gede-Pangrango and Ciwidey). The historical range totals 11,600 km2. Although it has been stated to occur at 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).

Ecology

Habitat

Habitat and Ecology

Habitat and 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).

Justification
This species has been downlisted to Vulnerable on the basis that its population is estimated to be larger than previously thought; however, its population remains small and inferred to be in on-going decline as a result of habitat loss and some trapping pressure.

Population

Population
The population size has been estimated to be as low as a few hundred pairs (Collar and van Balen 2002); however, it is easily overlooked, and there is still extensive forest east of Cibodas/Halimun that remains to be surveyed, thus it may be more common and widespread than recent observations suggest (B. van Balen in litt. 2013). It seems likely that more than 250 mature individuals occupy each of the large areas of forest at Gunung Gede and Halimun (C. Robson in litt. 2013). The species's population is therefore placed in the band for 2,500-9,999 mature individuals.

Threats

Major Threats
Forest loss, degradation and fragmentation, through widespread agricultural encroachment and localised development (e.g. holiday resorts and geothermal projects), are on-going threats in the species's altitudinal range. It also appears to suffer limited trapping pressure (A. A. Supriatna in litt. 2012, B. van Balen in litt. 2013).

Management

Conservation Actions

Conservation Actions
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.

Wikipedia

Javan trogon

The Javan trogon (Apalharpactes reinwardtii) is a species of bird in the Trogonidae family. The species was once lumped together with the Sumatran trogon in a single species, the blue-tailed trogon, but differences in size, weight and plumage have led to the two being split.[2] These two species were once themselves lumped with the rest of the Asian trogons in the genus Harpactes, but have been split into their own genus due to differences in plumage.

The Javan trogon is endemic to the west of Java in Indonesia.

Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss.
