Bird life of Indonesia (Sumatera Island)

The species are depicted on the Bird Life International series of Indonesia, Julang Jambul Hitam, Luntur Kasumba, Mentok Rimba, Cekakak Hutan Melayu, Kuau Raja and Bangau Storm. All specieses as " Puspa Hutan Sumatra" are found in Sumatera Island.

Julang Jambul Hitam (Aceros corrugatus)

The Aceros corrugatus is a medium-large hornbill which is found in forest in the Sundaic lowlands of peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Singapore (formerly), Kalimantan and Sumatra (including the Batu Islands), Indonesia and Brunei. Also well known as Wrinkled Hornbill or Sunda Wrinkled Hornbill

The Wrinkled Hornbill is around 70 cm long, and has a very large bill that is fused to the skull. It has mainly black plumage, a blue eye-ring, and a broadly white or rufous-tipped tail. The male and female have different head and bill patterns. Males have bright yellow feathers on the auriculars, cheeks, throat, neck-sides and chest, but these areas are black in the female, except for the blue throat. The bill of the male is yellow with a red base and casque, and a brownish basal half of the lower mandible. The bill and casque of the female is almost entirely yellow.
This is a forest species and eats mainly fruit, such as figs, although it will also eat small animals such as frogs and insects. Wrinkled Hornbills do not drink, but get the water they need from their food.

These birds are monogamous and remain in a pair for life. This species occurs in primary evergreen and swamp forests, up to 1,000 m. Due to high rates of deforestation in primary forests, it is cause to decline their population moderately rapidly. Hence this species should be carefully monitored as Near Threatened Bird.

Luntur Kasumba

The Luntur Kasumba (Harpactes kasumba) , also known as Red-naped Trogon is a species of bird in the Trogonidae family. It is found in Brunei, Indonesia, Malaysia, Singapore, and Thailand. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.

Mentok Rimba

The Mentok Rimba or Cairina scutulata , also known as White-winged Wood Duck is a species of duck, usually placed in the genus Cairina and allied with the dabbling ducks.

Historically, the White-winged Wood Duck was widely distributed from north-east India and Bangladesh, through South East Asia to Java and Sumatra. However, in 2002 it had a population of only 800, with about 200 in Laos, Thailand, Vietnam and Cambodia, 150 on Sumatra, notably in Way Kambas National Park and 450 in India, Bangladesh and Burma.

Due to ongoing habitat loss, small population size, and because this duck is hunted for eggs, pets and food, the White-winged Duck is evaluated as Endangered on the IUCN Red List of Threatened Species.

Cekakak Hutan Melayu

The Cekakak Hutan Melayu (Actenoides concretus), also known as Rufous-collared Kingfisher is a species of bird in the Alcedinidae family. It is found in Brunei, Indonesia, Malaysia, Myanmar, Singapore, and Thailand. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montanes. It is threatened by habitat loss.

Kuau Raja

The Kuau Raja or Argusianus argus (also known as Great Argus , Phoenix in some Asian areas) is a brown-plumaged pheasant with a small blue head and neck, rufous red upper breast, black hair-like feathers on crown and nape, and red legs. The male is among the largest of all pheasants, with up to 200cm in length. It has very long tail feathers. The male's most spectacular features are its huge, broad and greatly elongated secondary wing feathers decorated with large ocelli. The female is smaller and duller than male, with shorter tails and less ocelli.

The Kuau Raja is distributed in the jungles of Borneo, Sumatra and Malay Peninsula in southeast Asia. Due to ongoing habitat loss and hunted in some areas, the Great Argus is evaluated as Near Threatened on the IUCN Red List. Population estimate are 100,000 numbers with trend decreasing in range estimate of 1,900,000 km2.

Their habitat in tall, dry, lowland primary and logged forests, mainly below 900 m, but can be up to 1,300 m. It is much sparser in deciduous forest and rare to absent from lowland peat swamp and white-sand heath forests.The Great Argus is thought to be polygamous in the wild, it is actually monogamous.

Bangau Storm

The Bangau storm or Ciconia stormi, also well known as Stom’s Stork is a large, approximately 91 centimetres (36 in) long, stork with black and white plumages, red bill, orange bare facial skin, red legs and yellow orbital skin. Both sexes are similar. The young has duller plumage and bare skin.

This species is found in undisturbed forest and freshwater habitats in Sumatra, Mentawai Islands, Borneo and peninsular Malaysia. The world population of the Storm's Stork is less than 500 individuals.

The Bangau Storm is a solitary bird, but is occasionally found in small groups. Its diet consists mainly of fish. It occurs at low densities in large, undisturbed blocks of level lowland forest, particularly freshwater and peat-swamp forests, on the floodplains of large rivers. Due to ongoing habitat loss, very small population size, limited range and overhunting in some areas, the Storm's Stork is classified as Endangered on the IUCN Red List of Threatened Species.
