Kuang Raya ( Great Argus )


The scientific name of the Great Argus was given by Carl Linnaeus in reference to the many eyes-like pattern on its wings. Argus is a hundred-eyed giant in Greek mythology. There are two subspecies recognized: Nominate argus of the Malay peninsula and Sumatra, and A. a. grayi of Borneo. William Beebe considered the two races to be distinct species, but they have since been lumped.



The great argus is a brown-plumaged pheasant with a blue head and neck, rufous red upper breast, black hair-like feathers on crown and nape, and red legs. The male is among the largest of all pheasants. He measures 160–200 cm (63–79 in) in total length, including a tail of 105–143 cm (41–56 in), and weighs 2.04–2.72 kg (4.5–6.0 lb). It has very long tail feathers. The male's most spectacular features are its huge, broad and greatly elongated secondary wing feathers decorated with large ocelli.

The female is smaller and duller than the male, with shorter tails and less ocelli. She measures 72–76 cm (28–30 in) in total length, including a tail of 30–36 cm (12–14 in), and weighs 1.59–1.7 kg (3.5–3.7 lb). Young males attain adult plumage in their third year.

Kuang Cermin ( Mountain Peacock-pheasant)



The mountain peacock-pheasant (Polyplectron inopinatum) also known as Rothschild's peacock-pheasant or mirror pheasant is a medium-sized, up to 65 cm long, blackish brown pheasant with small ocelli and long graduated tail feathers. Both sexes are similar. The male has metallic blue ocelli on upperparts, green ocelli on tail of twenty feathers and two spurs on legs. Female has black ocelli on upperparts, unspurred legs and tail of eighteen feathers. The female is smaller and duller than male.

A shy and elusive bird, the mountain peacock-pheasant is distributed and endemic to montane forests of the central Malay Peninsula. The diet consists mainly of berries, beetles and ants.

Mitochondrial DNA cytochrome b and D-loop as well as the nuclear ovomucoid intron G data confirms that this species belongs to a clade together with the bronze-tailed peacock-pheasant, Germain's peacock-pheasant and grey peacock-pheasant (Kimball et al. 2001).

The molecular data suggests - though not with high confidence - that this species diverged from mainland stock earlier than the bronze-tailed peacock-pheasant. This is quite spurious, since its biogeography and derived plumage, and the fact that it is a peninsular mountain endemic indicate it is derived from a fairly small founder population; this would confound molecular analyses. What seems clear is that the present species evolved from mainland Southeast Asian stock, probably during the Late Pliocene to Early Pleistocene (3.6-1 myr[2]). The unique pattern of wings and tail thus is, contrary to long-held opinion, an autapomorphy, and the southern species of this clade - formerly separated in the genus Chalcurus - are probably not each other's closest relatives.

Due to ongoing habitat loss, small population size and limited range, the mountain peacock-pheasant is evaluated as Vulnerable on the IUCN Red List of Threatened Species
