Monal dell'Himalaya

Identificazione

It is a relatively large-sized pheasant. The bird is about 70 cm (28 in) long. The male weighs up to 2,380 g (84 oz) and the female 2,150 g (76 oz). The adult male has multicoloured plumage throughout, while the female, as in other pheasants, is more subdued in colour. Notable features in the male include a long, metallic green crest, coppery feathers on the back and neck, and a prominent white rump that is most visible when the bird is in flight. The tail feathers of the male are uniformly rufous, becoming darker towards the tips, whereas the lower tail coverts of females are white, barred with black and red. The female has a prominent white patch on the throat and a white strip on the tail. The first-year male and the juvenile resemble the female, but the first-year male is larger and the juvenile is less distinctly marked.

Areale e habitat

The Himalayan monal's native range extends from Afghanistan and Pakistan through the Himalayas in India, Nepal, southern Tibet and Bhutan.In Pakistan, it is most common in the Khyber Pakhtunkhwa province and has also been recorded in Kaghan, Palas Valley and Azad Kashmir. In India, it has been recorded throughout the Indian Himalayan Region from Jammu and Kashmir to Arunachal Pradesh.It lives in upper temperate oak-conifer forests interspersed with open grassy slopes, cliffs and alpine meadows between 2,400 and 4,500 m (7,900 and 14,800 ft), where it is most common between 2,700 and 3,700 m (8,900 and 12,100 ft). It descends to 2,000 m (6,600 ft) in the winter. It tolerates snow and digs through it to obtain plant roots and invertebrate prey.[citation needed]

Vertical migration

Comportamento

The diet of the Himalayan monal consists primarily of tubers, nuts, tender leaves, shoots, insects and other invertebrates. It digs in snow for shoots and invertebrates. Plant matter made up a large part of the diet, although invertebrate matter was also present in low percentages.

Conservazione

In some areas, the Himalayan monal is threatened due to poaching and other anthropogenic factors. In the western Himalayas, the population responded negatively to human disturbance involving hydroelectric power development. It is not considered endangered in Pakistan and can be easily located. In some areas, the population density of the species is as high as five pairs per square mile. The main threat to the species is poaching, as the crest is valuable. It is thought to bring status to its wearer and is a symbol of authority.
