Endangered
Bornean Peacock-Pheasant
Polyplectron schleiermacheri
The Bornean peacock-pheasant is a medium-sized pheasant.
Appearance
The pheasant is up to 50 cm long, rufous brown and black spotted, with an elongated crest and nape feathers, black below and bare red skin around bluish iris eye. The breast sides are metallic blue-green, bordering the white throat and central upper breast. Its twenty-two tail feathers are decorated with large blue-green ocelli, that may be spread fan-like in display.
Range and habitat
Endemic to Borneo, where it has been observed throughout the country, although its exact distribution is unknown. It inhabits lowland forests along the upper reaches of rivers, especially between 100 and 500 m above sea level, and appears to be absent from humid and swampy forests (O'Brien & Kinnaird 1997). This elusive bird is endemic to lowland forests of Borneo.

Diet and breeding
Its diet consists of fruits, seeds, and invertebrates, and is thought to be the source of seasonal movements linked to food availability (O'Brien & Kinnaird 1997). Its presence is particularly noticeable during the breeding season, due to the calls uttered by the males and the arenas they maintain, cleared of leaves, for courtship (Hennache & Ottaviani 2006).
It is currently unknown, but they are likely solitary birds. According to Seitre (2004), who visited the Rezit Sozer breeding farm in Java, it is extremely difficult to keep both members of a pair together outside the breeding season. On the other hand, Kuah (in litt.) breeds Bornean spur-tails in pairs, like other species, and even in trios, without encountering major problems, except for constant infertility when the partners do not get along.
In crisis
Because of ongoing habitat loss, small population size, and limited range, the Bornean peacock-pheasant is evaluated as Endangered on the IUCN Red List of Threatened Species.
CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
