The copper pheasant (Syrmaticus soemmerringii), also known as Soemmerring's pheasant or yamadori (山鳥),[2] is a pheasant endemic to the Japanese archipelago. The scientific name commemorates the German scientist Samuel Thomas von Sömmerring. It is the official bird of multiple Japanese prefectures. It was commonly hunted for sport throughout the 20th century.

Its populations has been in consistent decline since the 1970's due to factors including habitat destruction and predation, but the most widely cited cause is overhunting.

Taxonomy[edit]

The copper pheasant was described in 1893 by Coenraad Temmerick[2] as Phasianus soemmerringii.[3] It was placed in the Syrmaticus genus in 1914 by William Beebe, based on similarities between the proposed genus's females.[4] The scientific name commemorates the German scientist Samuel Thomas von Sömmerring,[5] while the ijimae subspecies is named for Isao Ijima[6]

Five subspecies of Copper pheasant are generally recognized, which become progressively darker further south in its distribution:

  • Soermmering's copper pheasant(S. s. soemmeringii) (Temminck, 1830) is found the northern and central Kyushu. The nominate subspecies, it is dark reddish in colour with an amber sheen to the rump and tips of the upper-tail coverts.
  • Ijima copper pheasant(S. s. ijimae) (Dresser, 1902) is found in southeastern Kyushu. It is similiar in appearance to soemmeringii, but the male has a white rump.
  • Scintillating copper pheasant(S. s. scintillans) (Gould, 1866) is found in northern and central Honshu. It is the palest subspecies, with broad white fringes on its belly and flanks.
  • Shikoku copper pheasant(S. s. intermedius) (Kuroda, 1919) is found in Shikoku and southwestern Honshu. Like scintillans, it has white fringes on its belly and flanks, but is darker.
  • Pacific copper pheasant(S. s. subrufus) (Kuroda, 1919) is found in southeastern Honshu and southwestern Shokoku. It has golden fringes on its rump and upper-tail coverts.

Description[edit]

It is a large pheasant with a rich coppery chestnut plumage, yellowish bill, brown iris, and red facial skin. The female is a brown bird with greyish brown upperparts and buff barred dark brown below. The male has short spurs on its grey legs, while the female has none. Males are between 87.5 centimetres (34.4 in) and 136 centimetres (54 in) long, including the tail, while the female is between 51 centimetres (20 in) and 54 centimetres (21 in) (subspecies scintillating copper pheasant, scintillans).[7] Juveniles have similar plumage to females.[8]

Distribution and habitat[edit]

The copper pheasant is distributed in and endemic to the hill and mountain forests of the Honshū, Kyūshū, and Shikoku islands[2] at elevations of up to 1,800 metres (1.1 mi).[9] It typically confines itself to deciduous forest floors with extensive vegetation. However, members of the species also lives in conifer forests. They often nest on the edges of grasslands.[10]

Behavior and ecology[edit]

The bird is not heavily vocal, only occasionally making a "kuk-kuk"-like call when breeding or threatened.[10][11] These pheasants are known to sunbathe, especially when living in grasslands. They roost in trees,[10] and are a non-migratory bird.[9]

Breeding[edit]

The copper pheasant's mating season occurs between March and July, with the exact month depending local climate. During this time, males perform their wing-whirring display[11] and fight other males in an attempt to secure a mate. It is unknown if the species in monogamous.[10]

Copper pheasants typically nest on the ground, but have also been recorded nesting in trees.[12] They often build their nests in locations sheltered by fallen trees.[11][10] Captive birds have a clutch of ten to twenty eggs, while wild birds only have a clutch of seven to thirteen eggs.[11] The cream-coloured[8] or tan[10] eggs take a little over three weeks to hatch, and young birds reach maturity in less than a year.[11] Young are raised by their mother, who will either pretend to attack potential predators or attempt to distract them when needed.[10]

Food and feeding[edit]

The diet consists mainly of insects, arthropods, and acorns,[13] but they also eat a substantial amount of leaf and fern matter.[10]

Threats[edit]

The copper pheasant serves as an important source of prey to Japanese populations of the golden eagle and Hodgson's hawk eagle.[14] It is susceptible to infection by the heterakis gallinarum parasite.[15]

Relationship to humans[edit]

In Japan[edit]

The copper pheasant appears in Japanese poetry as far back as poetry composed by Kakinomoto no Hitomaro in the early 8th century, as compiled in the Hyakunin Isshu:[16]

Ashibiki no yamadori no wo no shidari-wo no naga-nagashi yo wo hitori ka mo nemu
Must I sleep alone through the long autumn nights, long like the dragging tail of the mountain pheasant separated from his dove?

Several screens, dating to the eighth century and incorporating copper pheasant feathers, are kept in the Shōsō-in temple. The screens were mistakenly assumed to be Chinese.[17] Unidentified bones of either copper pheasants or chickens have been found at Japanese archaeological sites from the Kofun period.[18]

The copper pheasant is a popular game animal in Japan.[19] They are hunted both as a source of food and a source of entertainment.[9]

It is the official bird of the Gunma[20] and Akita prefectures.[21]

Outside Japan[edit]

Outside of Japan, the copper pheasant is kept as a pet or display animal.[9]

In 1922, an addendum to the Plumage Act of 1908 halted the importation of copper pheasant feathers into the UK. They were removed from the list after a year.[22]

From 1907 to 1914, there was a series unsuccessful attempts to establish copper pheasants colonies on the Hawaiian islands.[23]

Status[edit]

As of 2016, the copper pheasant was listed as "Near Threatened" on the IUCN Red List of Threatened Species, with the exact number of wild adults unknown. It has been listed as "Near Threatened" since 2004, but had previously held the same classification in 1988.[9] The ijimae subspecies is protected in Japan.[24]

In 1995, an IUCN report called for the continued monitoring of the species, citing over-hunting and a lack of knowledge about the species' behaviour as a reason to study and protect them.[25] Threats to the species include non-native predation, overhunting, and habitat destruction.[9] Feral dogs and cats disturb nesting sites, further negatively impacting the species.[26] However, overhunting is widely considered as the greatest threat to the species.[9][19][27]

Throughout the twentieth century, until the introduction of legal protections, half a million[19][24] to 800,000[28] copper pheasants were killed by hunters every year. In 1976, to prevent further decline of the species, it was made illegal in Japan to hunt female copper pheasants.[19][9] The number of birds hunted decreased to 100,000 per year in the 1990s.[28]As of 2006, the number of birds killed annually had dropped to 6,000.[14] To allow for hunting, copper pheasants are bred and released every year throughout Japan,[24] including in regions such as Hokkaido and Sado Island, where they are a non-native species.[10]
