The Key to Scientific Names
Legend Overview
Field Identification
Male c. 65 cm (tail 32–40 cm); female c. 46 cm (tail 22–27·5 cm). Long-bodied and long-tailed peacock-pheasant that lacks obvious crest; easily separated from P. malacense by darker head and underparts, reddish-brown upperparts and longer, narrower tail (1). Characteristic contrast between mainly chestnut mantle, wings and back , and greyish-black underparts and head. Male has very small blue ocelli (with a white spot at the base of each ocellus) on mantle and wings. Female resembles male but is considerably smaller, with shorter tail; ocelli on upperparts replaced by black spots. Bill and legs grey, and irides brown; male has one or two spurs (2), female none (1). Female Rheinardia ocellata and Argusianus argus are both much larger with distinctive head patterns (1). First-year male is smaller and duller than adult female (1). Juvenile similar to adult female, but young male is longer-legged.
Systematics History
Subspecies
Distribution
Mountains of Peninsular Malaysia from Cameron Highlands S to Genting Highlands, in Larut Range to NW, and on E outlying peaks Gunung Tahan and Gunung Benom. Some evidence that the species occurs also in extreme S Thailand (5).
Habitat
Occurs throughout unlogged upper dipterocarp forest , and both lower montane and upper montane forest, from 820 m (1) up to 2000 m, with one record of a feather at 600 m perhaps indicating that the species at least occasionally, or locally, occurs lower (1).
Movement
No information available.
Diet and Foraging
One crop contained spiders, white ants, several grubs and other unidentified animal material; also reports of birds having consumed other invertebrates (e.g. beetles) (1) and fruits of rattan Calamus. No further information available.
Sounds and Vocal Behavior
Considered to be generally less vocal than congenerics (1). Male territorial call comprises 1–4 (usually two) loud buzzing, drawn-out squawks or clucks, with a slightly electric quality, given in bouts 5–6 seconds apart; alarm call is similar to clucks of domestic chicken; also gives a burbling, descending whistle (1).
Breeding
Season apparently suspected to usually commence in Jan, based on female on lightly incubated eggs in Jan in Malaysia, small chick collected in late Feb and half-grown young with female in Jun (2). Mating system assumed to be monogamous, based on limited sexual dimorphism (1), but no concrete data. Male display (from observations in captivity) includes body-shakes, rapid walking while alternately flexing each wing, walking erectly while flapping spread wings, drooping the flight feathers and tilting the tail towards female, near-frontal display with lowered breast, raised wing and cocked tail, high-stepping movements with head and neck feathers ruffled, head-bobbing, and ritual food-passing (2). Very little information from the wild: an old nest found at altitude of 970 m, placed among rocks between two fallen trees, while another was a virtually unlined scrape (26 cm by 10 cm) (2) under a rhododendron in dense elfin forest (1). In captivity: clutch of two buffy-white (1) eggs, 51·3–53 mm × 43·8–44 mm (2); incubation 19–21 days, by female alone (1); chicks have rufous down above, buff below.
Conservation Status
VULNERABLE. Mace-Lande: vulnerable. CITES III in Malaysia. Based on anecdotal information and extent of habitat available, population is estimated to be 2500–10,000 mature individuals within overall range of 12,700 km², and is probably stable or declining slightly. Present in Fraser’s Hill (30 km²) and Cameron Highlands (649 km²) Wildlife Sanctuaries, Krau Wildlife Reserve (530 km²) and Taman Negara National Park (4343 km²). Known from total of 14 localities, but at just six has the species been recorded since the 1970s, at two of which the species is described as common (6). Species has restricted range, occurring in Sumatra and Peninsular Malaysia (above 600 m) Endemic Bird Area, although strongly suspected to also occur in S Thailand in Yala province, based on a tail feather thought to be of this species (7). Threatened by habitat destruction for agriculture and possibly also by urban development. Major threat is possibility of a road linking the hill stations of Genting Highlands, Fraser’s Hill and Cameron Highlands, which would destroy much montane forest along Main Range. An international studbook and breeding consortium was initiated during 1992 and is co-ordinated by New York Zoological Society/Wildlife Conservation International and Department of Wildlife and National Parks, Peninsular Malaysia; the captive population comprised 111 individuals in Feb 1993.
