Genus

Apalharpactes is a genus of birds in the Trogonidae family. They are restricted to humid highland forest on the Indonesian islands of Java and Sumatra. Unlike all other Asian trogons, their plumage is mainly green above and yellow below. Compared to most trogons, the sexual dimorphism is relatively small. The two species in the genus resemble each other, but A. reinwardtii is larger than A. mackloti, and the male A. mackloti has a chestnut rump-patch, which A. reinwardtii lacks. They feed on arthropods, small lizards and fruit. The members of Apalharpactes are sometimes placed in the genus Harpactes instead. The two species of Apalharpactes were formerly treated as conspecific under the name Red-billed Trogon or Blue-tailed Trogon (Apalharpactes reinwardtii, with mackloti as a subspecies).

Physical charateristics

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”

Range

Oriental Region : Java. 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 11600 km2. Although it has been stated to occur from 800-2600 m, little forest remains below 1000 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

Habitat

Appears to favour mid-montane forest

Reproduction

Little known; breeding reported April through December; lays one to three eggs.

Feeding habits

It feeds on a variety of invertebrates taken by aerial sallying or by perch-gleaning. Also feeds on fruit and will occasionally join mixed-species flocks.

Conservation

This species is considered to be Endangered because it has a very small population which is likely to be declining owing to habitat loss.
Forest loss, degradation and fragmentation, through widespread agricultural encroachment and localised development (e.g. holiday resorts and geothermal projects), is becoming an increasing threat in the altitudinal range of the species

Migration

Presumed sedentary
