Biology

provided by Arkive
This pheasant roosts in trees at night (6) and forages on the ground by day, with most feeding seeming to occur in the morning and late afternoon, typically along trail edges (4) (9). Swinhoe's pheasants have a varied diet, including acorns, berries, flower buds, leaves and other plant material, as well as a few earthworms, millipedes, termites and other insects (4) (9). Though these pheasants typically feed alone, they may be seen in small groups or with their young during the breeding season (6). During the breeding season, from March until July, males perform impressive courtship displays to entice females to mate (4). This involves flaunting their brilliant metallic plumage and erecting their white crest and red face wattles, while they bob their head up and down, jump around and whirr their wings (2). Peak egg-laying probably occurs in March and May, although reports as late as October exist (9). Nests are built in highly secretive, well hidden places under large shelters, such as at the foot of a tree or under rocks, and occasionally in trees, where they are safe from the rain and predators (6) (9). Clutches of three to eight eggs are laid and then incubated for around 25 days (in captivity) by the female alone (4) (9).

Conservation

provided by Arkive
Swinhoe's pheasant occurs in several protected areas, including Yushan National Park, where an estimated 6,500 individuals live (8). The greatest priority for the conservation of this, and other native, species in Taiwan must be to preserve the remaining tracts of forest that support them (6).

Description

provided by Arkive
The Swinhoe's pheasant cock is a spectacular bird, boasting a glossy black plumage with brilliant metallic blue lustre, and a bold and distinctive pattern of white patches on the upper back, crest and long central tail feathers (4) (5) (6). The shoulders are a dark, shimmering maroon, and conspicuous crimson-red legs and face wattles inject a splash of vibrant colour (4) (5). Females are smaller and mostly greyish-brown, speckled with triangular yellow-buff markings, for camouflage when incubating (6) (7).

Threats

provided by Arkive
In the past, Swinhoe's pheasant suffered from heavy hunting pressure, but poaching no longer poses a serious threat (8). The species' habitat has also been subject to a variety of pressures, and this bird is known to have become extinct in several areas in the 1960s and 1970s, although it apparently remains common where suitable habitat exists (8) (9). Numbers are thought to be stable in protected areas, but declining elsewhere as a result of ongoing pressures on its forest environment (8).

Swinhoe's pheasant

provided by wikipedia EN

Swinhoe's pheasant (Lophura swinhoii), also known as the Taiwan blue pheasant, is a bird of the pheasant subfamily in the fowl family Phasianidae. It is endemic to Taiwan. Along with the Mikado pheasant and Taiwan blue magpie, two other Taiwan endemics, Swinhoe's pheasant is sometimes considered an unofficial national symbol for Taiwan, as it bears the colours of the national flag (red, white, and blue).

Etymology

The bird was named after British naturalist Robert Swinhoe, who first described the species in 1862. Locally, the species is known in Mandarin as lánfùxián (Chinese: 藍腹鷴; lit. 'blue-breasted kalij'), and in Taiwanese Hokkien as wa-koe (華雞; hôa-koe; 'flowered fowl'; also 畫雞).[3]

Description

The male Swinhoe's pheasant can grow up to 79 cm. He has a glossy blue-purple chest, belly, and rump, white nape, red wattles, white tail feathers, and a white crest. The female is brown marked with yellow, arrow-shaped spots and complex barring patterns, and has maroon outer rectrices. The juvenile male is dark blue with brown and yellow patterns on its wings. Swinhoe's pheasants can also be distinguished from the Mikado pheasant by having red legs.

During display, the male's wattles become engorged and he performs a display consisting of a hop followed by running in a circle around females. A frontal display with the tail fanned is occasionally observed. He also does a wing-whirring display like other Lophura pheasants.

Habitat

Swinhoe's pheasant is found in the mountains of central Taiwan, where it lives in primary broadleaf forest up to 2,300 m in elevation.[1]

Behaviour

Swinhoe's pheasant eats seeds, fruits, and some insects and other animal matter. Predators include the crested goshawk, white-bellied sea eagle, Gurney's eagle, spot-bellied eagle-owl, and the civet and badger.

The female lays a clutch of two to six eggs, which are incubated for 25 to 28 days. The young can leave the nest at 2-3 days old. Swinhoe's pheasant is often assumed to be polygynous, as males are often seen with several females, though confirmation is lacking.

Conservation

This pheasant has a small population in a limited range that is shrinking due to habitat degradation. Logging is a problem. It was hunted in the past, and some populations were extirpated in the 1960s and 1970s. Today, its global population is estimated to be over 10,000 individuals.[1] Some populations are secure within protected areas, but others may be declining. Alongside the Mikado pheasant and Taiwan magpie, they are sometimes unofficially considered national symbols of Taiwan, which has helped in their conservation and protection. In some areas, such as Dasyueshan National Forest Recreation Area, they are regularly sighted feeding along roadsides, which have become bird-watching hotspots. Often they are fed by bird photographers, which has considered a controversial practice by some conservationists and liable to a fine by park officials.
