Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.
Arborophila charltonii, A. tonkinensis, and A. graydoni (del Hoyo and Collar 2014) were previously lumped as A. charltonii following Sibley and Monroe (1990, 1993).
26-32 cm. Boldly-marked partridge with chestnut collar and ear-patch. A. c. tonkinensis has narrower chestnut collar and smaller, pale chestnut ear-patch. Similar spp. From Bar-backed Partridge A. brunneopectus by plainer upperside, heavy black breast markings, reddish bill with greenish tip, greenish to yellowish-green legs and distinctive ear-patch and collar. From extralimital Scaly-breasted and Annam Partridges A. merlini by chestnut ear-patch and collar. Voice Similar to Scaly-breasted (see Annam).
Distribution and population
Arborophila charltoni has a disjunct, mainly Sundaic distribution ranging (race charltoni) from southern Myanmar and southern Thailand into Peninsular Malaysia, and is present (race atjenensis) in two isolated areas (Aceh and South Sumatra) of Sumatra, Indonesia, and occupies a wide area of Sabah (Borneo), Malaysia (race graydoni) (BirdLife International 2001). An outlying population (race tonkinensis, formerly treated under Green-legged Hill-partridge A. chloropus) occurs in east Tonkin and north Annam, Vietnam. Estimates of numbers are of possibly under 10,000 (100-10,000) (charltoni), 10-100 (atjenensis), 100 (graydoni), with tonkinensis locally quite common and in three protected areas. Graydoni is now known to be quite common in Danum Valley, Sabah.
This species inhabits lowland forest to 500 m. It is noted to be scarcer in logged forest.
Forest destruction in the Sundaic lowlands of Indonesia and Malaysia has been extensive (Kalimantan lost nearly 25% of its evergreen forest during 1985-1997, and Sumatra lost almost 30% of its 1985 cover), because of a variety of factors, including the escalation of logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas, plus forest fires (particularly in 1997-1998). Declines caused by habitat loss are compounded by trapping for the cage-bird trade. However, the species's use of secondary growth and higher elevations implies that it is not immediately threatened.
Conservation Actions Underway
None is known. Conservation Actions Proposed
Survey to assess the size of all sub-populations. Monitor trends in all sub-populations. Research the species's tolerance of logged forest. Protect large areas of primary and old secondary forest within its range.
