Faisán dorado

Identificación

The adult male is approximately 100 cm (39 in) in length, with its tail accounting for two-thirds of the total length, and around 500–700 g (1–2 lb) in weight. Its coloration is characterized by a golden crest and rump and by a bright red body. It possess an orange ruff or "cape" on the beck that can be spread in display, appearing as an alternating black and orange fan that covers all of the face except for the eyes. The eye is bright yellow, with a pinpoint black pupil. The face, throat, chin, and the sides of neck are rusty tan. The wattles and orbital skin are both yellow. The upper back is green and the rest of the back and rump is golden-yellow. The tertiary feathers on the wings are blue, whereas the scapulars are dark red. The central tail feathers are black spotted with cinnamon, while the tip of the tail is a cinnamon buff. The upper tail coverts are the same colour as the central tail feathers. The male also has a scarlet breast, and scarlet and light chestnut flanks and underparts. Lower legs and feet are a dull yellow.<p>The adult female (hen) is 60–80 cm (24–31 in) in length and weights around 350 g (1 lb). Her tail is proportionally longer, and makes up roughly half of her total length. She is much less showy than the male, with a duller mottled brown plumage similar to that of the female common pheasant, but is darker and more slender. The female's breast and sides are barred buff and blackish brown, and the abdomen is plain buff. She has a buff face and throat. Some abnormal females may later in their lifetime develop some male plumage. Both males and females have yellow legs and yellow bills.

Distribución y hábitat

The golden pheasant is native to forests in mountainous areas of western China, but feral populations have been established in the United Kingdom, Canada, the United States, Mexico, Colombia, Peru, Bolivia, Chile, Argentina, Uruguay, the Falkland Islands, Germany, Belgium, the Netherlands, France, Ireland, Australia and New Zealand. In England they may be found in East Anglia in the dense forest landscape of the Breckland as well as Tresco on the Isles of Scilly.[citation needed]<p>Golden pheasants were introduced to Maui, in Hawaii, at some point before their first detection in 1996. The original birds were released in Waikamoi Preserve, where the founder population has showed evidence of reproductive behavior. Secondary groups were later recorded in Hanawï Natural Area Reserve and Haleakalä National Park, where they most probably arrived through dispersal from Waikamoi. Overall, the pheasants inhabit areas between 1,700–2,400 m (5,577–7,874 ft) on the windward slope of the island.

Comportamiento

Golden pheasants feed on the ground on grain, leaves and invertebrates, but they roost in trees at night. During winter, flocks tend to forage close to human settlements at the edge of forest, taking primarily wheat leaves and seeds. While they can fly clumsily in short bursts, they prefer to run and spend most of their time on the ground. This type of flying is commonly known as "flapping flight" and is due to a lack of a deep layer of M. pectoralis pars thoracicus and the tendon that attaches to it. This muscle is commonly attributed to the stabilization of flight in other birds; however, the absence of this deep layer causes this mode of "flapping flight" is simply a mechanism that it shares with other ground birds in order to escape predators. However, they would rather prefer to simply run away and hide from their predators rather than to fly.<p>Golden pheasants lay 8 to 12 eggs at a time and will then incubate these for around 22–23 days. They tend to eat berries, grubs, seeds and other types of vegetation.[citation needed]<p>The male has a metallic call in the breeding season.[citation needed]
