Last update date April 1, 2024
Introduction of Walldrapp Ibis, Congo Peacock Vietnamese Pheasant
Introducing Walldrapp Ibis, Congo Peacock and Vietnamese Pheasant raised in Preservation and Research Center.
Walldrapp Ibis Waldrapp Ibis
<scientific name> Geronticus eremita
The total length is 70-80 cm, the body is green and glossy black, the light rain cover is bronze purple, and the beak and legs are red. As it grows, the feathers of the head fall off and becomes bald, and the neck feather grows longer. Males are slightly larger than females, but there is no obvious difference in appearance in male and female. It lives in small groups and relatively dry areas and feed on small animals such as grasshoppers. A colony is formed on a high cliff rock shelf and nests, and male and female jointly engages in eggs and grow chicks. The clutch size is 2 to 4. The chicks hatch in about 28 days and nest in 40 to 50 days.
Until the 17th century, it was distributed to Western Europe, but now it inhabits only a small area in Turkey and Morocco, and is designated as an endangered species. In Turkey, only 55 birds are left in Birecik in eastern Birecik, near the border with Syria and around 220 birds in Sousss-Massa National Park in Morocco, and the population that inhabited Algeria are considered to be extinct.
On the other hand, about 1,000 birds are bred around the world, including European zoos, and some institutions are planning to return to the wild.
Congo Peacock Congo Peacock
<scientific name> Afropavo congensis
Congo Peacock is a family of peacock that inhabits the tropical rainforests at an altitude of 1,200 meters from the lowlands of the Republic of the Congo and the Democratic Republic of Congo and the Democratic Republic of Congo.
With a total length of 60cm to 70cm and weighing 1,100g to 1,500g, almost the same size in male and female. Males have long white and long crowns, the skin of the bare throat is red, the chest to the bottom is covered with dark purple feathers, the upper surface is deep green, and the tip of the tail feather and the tip of the middle rain cover are blue metal. There is a light metal bluster. There are no long and fine feathers, as seen in other peacocks, Great Argus, and Polyplectron. Females are not as long as males, but have brown crowns, their throats are covered with brown feathers from chest to bottom, and shiny green back.
It lives mainly on the ground during the day and sleeps on trees at night. It eats various plants and insects, including fruits, seeds, etc.
There is no particular breeding season in the wild, and breeding is said to be affected by rainfall conditions. When the estrus begins, the male raises its tail feathers, spreads its white crown, and approaches the female, making a glue and peering voice. Nests are made on the ground or on a tree and lays two to three eggs in one clutch. The incubation is performed only by females, and the chicks hatch in about 28 days.
The male and female cooperates with each other. The chicks have wings since they were born and will be able to fly gradually five days after birth. The chicks initially have yellow and brown mottled patterns and cannot be distinguished between male and females, but three months after birth, their wings change and each male and female has their wings.
Congo Peacock was discovered relatively new in 1936, and until then it was believed that the peacock companions were distributed only in Asia and would not live in Africa. It is a rare animal that has been protected by law early on, and still requires special permission to capture. It has been bred in the United States since 1949 and in Western Europe in 1957, and currently about 100 birds are bred around the world. The Royal Antwerp Zoo, located in Belgium, which ruled the Democratic Republic of Congo, manages the International Studbook in Congo Peacock, has established a fund to focus on conservation.
Only Preservation and Research Center, City of Yokohama is bred in Japan.
Vietnamese Pheasant Vetnamese Pheasant
<scientific name> Lophura hatinhensis
It is distributed only in very limited areas of central and northern Annamite Range in central Vietnam.
A total length of 58-65cm and weighs about 1,100g. Males are dark blue with a deep purple luster, and have a short white crown. Red skin is naked around the eyes, and this skin is widened during courtship. The female is brown overall, and the lower surface, wind feathers, and tail feathers are blackish. The bare skin around the eyes are red, but not as large as males. The male central feathers are white and distinguished from Edwards's Pheasant (Lophura edwardsi), which inhabits the same central Annamite Range, but females do not have this characteristic and cannot be distinguished from Edwards's Pheasant.
The habitat is a lowland covered with secondary forests and evergreen trees at an altitude of 50 to 200m. It prefers a riverside area full of plants, and feeds seeds, fruits, insects, etc. Clutch size is 4 to 7 eggs, and the incubation period is 21-22 days. The chicks are brown on the top and pale yellowish brown on the face and bottom surface.
It was once regarded as a variant of Edwards's Pheasant, or a completely different independent species, but it has recently been treated as a mutant of Edwards's Pheasant.
Critically Endangered (CR) is a Edwards's Pheasant in the Red List of the International Union for Conservation of Nature.
