The trogons are split into three subfamilies, each reflecting one of these splits, Aplodermatinae is the African subfamily and contains a single genus, Apaloderma; Harpactinae is the Asian subfamily and contains two genera, Harpactes and Apalharpactes. Apalharpactes, consisting of two species in the Java and Sumatra, has only recently been accepted as a separate genus from Harpactes. Harpactes is a genus of birds found in forests in South and Southeast Asia, extending into southernmost China. They are strongly sexually dimorphic, with females generally being duller than males. The two members of the genus Apalharpactes are sometimes included in Harpactes.
Male black head and upper breast, blue bill and eye ring with blue face skin. Yellow-brown upperparts and upper tail with black outlines. White breastline. Bright red under parts, undertail black white. Female grey brown head and upper breast with vague line, yellowish underparts.

This species occurs in lowland forests in a region experiencing undergoing rapid deforestation through logging and conversion to agriculture. Although it may tolerate very low-intensity logging, it is likely to be declining moderately rapidly across much of its range, and it is therefore considered Neat Threatened. Rates of forest loss in the Sundaic lowlands have been extremely rapid, owing partly to the escalation of illegal logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas. Forest fires have also had a damaging effect

PoB staff news
If you hear a mourning-dove around your house, some one in the house will die unless you tie a knot into each corner of your apron. Then the mourning-dove will stop mourning and go away.
Dear visitor, we started two exciting new projects on PoB. Unique on the net we started posting Vintage plates and bird descriptions from the dawn of ornithology. Next to this we collected stories about birds in mythology, fables and folk lore. Many of these stories are founded in what is nowadays called ethno-ornithology. The next few months we will be publishing about 2000 new posts... The past months were quiet on the posting front, but frantic in research. Enjoy and help us by posting or commenting your own stories, fables or bird legends.
Chief editor PoB.
Buzzards never build a nest, because small birds say to them, "when the sun shines, what is the use of building a nest? Sun shine. When it rains, build when the rain stop." Dumb Buzzard never does build a nest.
