2-6-2023 BALI BIRD PARK, BALI - GREAT ARGUS (Argusianus argus)

The great argus (Argusianus argus) is a species of pheasant from Southeast Asia.

Description

The great argus is a brown-plumaged pheasant with a blue head and neck, rufous red upper breast, black hair-like feathers on the crown and nape, and red legs.

Unusual among Galliformes, the great argus has no uropygial gland.

The male clears an open spot in the forest and prepares a dancing ground. He announces himself with loud calls to attract females, then he dances before her with his wings spread into two enormous fans, revealing hundreds of "eyes" while his real eyes are hidden behind it, staring at her.

Breeding

Despite displays similar to polygamous birds and though the great argus was thought to be polygamous in the wild, it has been discovered that it is actually monogamous. The hen lays only two eggs.

Distribution and habitat

The great argus is native to the jungles of Borneo, Sumatra and the Malay Peninsula in southeast Asia.

2-6-2023 BALI BIRD PARK, BALI - MALAYAN EGGFLY BUTTERFLY (Hypolimnas anomala)

Hypolimnas anomala, commonly known as the Malayan eggfly or crow eggfly, is a species of eggfly. Distribution and habitat

Distribution and habitat

This species is present as various subspecies in South East Asia (Moluccas, New Guinea, Australia). It especially occurs in lowlands and tropical rainforests, wastelands, hill parks and natural reserves.

Description

Hypolimnas anomala can reach a wingspan of 65–75 mm (2.6–3.0 in). These butterflies have brown forewings with a purple sheen. They show variable white markings. Usually there are a double row of white marginal spots and three pale streaks on each forewings. The hindwings are rather paler, with dark brown veins. The undersides of both wings are similar to the uppersides. In the adult butterflies only four legs are present. These butterflies mimic Euploea species.

Biology

Females lay golden in colour globular eggs in a large cluster on the underside of the leaves. They hatch after about 3–4 days. The 6th (and final) instarcaterpillars are black with yellow spots and spines. Also the head is yellow. with long black cephalic horns. They are gregarious and usually occur in large numbers.

They feed on leaves of Urticaceae (Pipturus argenteus, Pipturus arboresceus, Pouzolzia, Villebrunea species ) and Euphorbiaceae (Claoxylon).

 

6-6-2023 UBUD, BALI - SAP SUCKING INSECT (Anoplocnemis phasianus)

Anoplocnemis phasiana is a species of sap-sucking insect in the genus Anoplocnemis. They are native to Asia where they are considered a major pest of many types of agricultural plants such as trees and shrubs, including legumes, sometimes known as the tip-withering bug.

 

5-6-2023 UBUD, BALI - SCALY BREASTED MUNIA (Lonchura punctulata)

The  scaly-breasted munia or spotted munia (Lonchura punctulata), known in the pet trade as nutmeg mannikin or spice finch, is a sparrow-sized estrildid finch native to tropical Asia. A species of the genus Lonchura, it was formally described and named by Carl Linnaeus in 1758. Its name is based on the distinct scale-like feather markings on the breast and belly. The adult is brown above and has a dark conical bill. The species has 11 subspecies across its range, which differ slightly in size and color.

This munia eats mainly grass seeds apart from berries and small insects. They forage in flocks and communicate with soft calls and whistles. The species is highly social and may sometimes roost with other species of munias. This species is found in tropical plains and grasslands. Breeding pairs construct dome-shaped nests using grass or bamboo leaves.

The species is endemic to Asia and occurs from India and Sri Lanka east to Indonesia and the Philippines (where it is called mayang pakíng). It has been introduced into many other parts of the world, and feral populations have established in Puerto Rico and Hispaniola, as well as parts of Australia, and the United States of America, with sightings in California. The bird is listed as of least concern by the International Union for Conservation of Nature (IUCN).

The scaly-breasted munia is about 11–12 centimetres (4.3–4.7 in) long and weighs 12–16 grams (0.026–0.035 lb). The adult has a stubby dark bill typical of grain eating birds, brown upperparts and a dark brown head. The underparts are white with dark scale markings. The sexes are similar, although males have darker markings on the underside and a darker throat than females.

Immature birds have pale brown upperparts, lack the dark head found in adults, and have uniform buff underparts that can be confused with juveniles of other munia species such as the tricolored munia (Lonchura malacca) across the Asian and island populations and the black-throated munia (Lonchura kelaarti) in parts of India or Sri Lanka.

Distribution and habitat

The scaly-breasted munia (subspecies topela) has established in parts of eastern Australia such as Queensland

Scaly-breasted munias are found in a range of habitats but are usually close to water and grassland. In India, they are especially common in paddy fields where they are considered a minor pest on account of their feeding on grain. They are found mainly on the plains, but can be observed in the foothills of the Himalayas, in which they may be present at altitudes near 2,500 m (1.6 mi), and in the Nilgiris, where they are found at altitudes up to 2,100 m (6,900 ft) during the summer. In Pakistan, they are restricted to a narrow region from Swat in the west to Lahore, avoiding the desert zone, and then occurring again in India east of an area between Ludhiana and Mount Abu. The species has also been observed in Kashmir, though this is rare.

Outside their native range, escaped birds frequently establish themselves in areas with a suitable climate and can then colonize new areas nearby. 

Outside their native range, escaped birds frequently establish themselves in areas with a suitable climate and can then colonize new areas nearby. Escaped cage-birds established in the wild and such populations have been recorded in the West Indies (Puerto Rico since 1971), Hawaii (since 1883, Australia, Japan and southern United States, mainly in Florida and California. In Oahu, Hawaii, they compete for habitats with the tricolored munia and tend to be rare where this competitor is present. The species has been introduced to other parts of the world due to its popularity as a cage bird and populations have established in the wild.

29-5-2023 TABIN RESERVE, BORNEO - RED BEARDED BEE-EATER (Nyctyornis amictus)

 

The red-bearded bee-eater (Nyctyornis amictus) is a large species of bee-eater found in southern Myanmar, the Thai-Malay Peninsula, Borneo, Sumatra and nearby smaller islands. This species is found in openings in patches of dense forest.

Like other bee-eaters, they are colourful birds with long tails, long decurved beaks and pointed wings. They are large bee-eaters, predominantly green, with a red colouration to face that extends on to the slightly hanging throat feathers to form the “beard”. Their eyes are orange.

27-5-2023 TABIN RESERVE, BORNEO - GOULD'S FROGMOUTH (Batrachostomus stellatus)

 Gould's frogmouth is a medium-sized bird that will approximately weight 47 to 48.5 g and measure 21 to 25 cm. It can be seen in two different morphs. They both have the same patterns except that one is light and the other one is dark. They are mostly brown and have a white collar with some scattered white spots on the cover of the wings. The underparts have oval-shaped spots that appears whitish. Contrarily to the other frogmouths, the males and females are very similar. However, some differences arise which permit their identification. The females will have a darker reddish-brown color. Moreover, females have brown iris and yellowish legs while the males have yellow iris and pinkish legs.

This species is found solely in Southeast Asia. More precisely, it is found in Brunei, certain regions of Indonesia, Malaysia, Singapore, and in Southern Thailand. However, it is mostly present in Malaysia and Singapore. The habitat of Gould's frogmouths is tropical rainforest. They are mostly found in forest with native tree species that has not been disturbed by humans. This species usually lives in lowland forests, up to 500 metres elevation.

Gould's frogmouths are insectivore like many other frogmouths in the area. They will feed on different types of moths, on certain beetles and on locusts.

The breeding season can differ depending on the location of the birds. In the Malaysian area, it is from June to September and in Borneo it is from February to July. The incubation time is about 30 days and both parents will do the incubation. The nest is made with some of the parent's down and is usually small and shallow. Using some branches and lichens, the parents hide the nest to protect it from predators. The nests are mostly found at 1.3 m high and the females will lay one egg per clutch. The eggs have an oval shape and are white.

According to the IUCN, the Gould's frogmouth species is categorized as near threatened. Its population is continuously decreasing. This is due to the threats to its habitat. In Southern Thailand, there is a critical decline in the bird populations living in the lowland areas because the deforestation of the lowland forests by humans is destroying the habitat of different species. Therefore, Gould's frogmouth species is facing local extinction in Thailand. However, this species is spread in many different regions of Southeast Asia, so it reduces the risks of total extinction.

27-5-2023 TABIN RESERVE, BORNEO - WHITE CROWNED HORNBILL (Berenicornis comatus)

 The white-crowned hornbill (Berenicornis comatus), also known as the long-crested hornbill or white-crested hornbill (leading to easy confusion with the African white-crested hornbill), is a species of hornbill.

It is monotypic within the genus Berenicornis, although rarely the white-crested hornbill is also included in this genus, and the white-crowned hornbill is sometimes placed in genus Aceros instead.

Berenicornis comatus. Close-up on the heads of male (right) and female (left)

Berenicornis comatus is a large hornbill, reaching a length of 83–102 cm (33–40 in) and a weight of 1.3–1.5 kg (2.9–3.3 lb). Females are smaller than males. The plumage is black and white. The head, neck, breast and tail are white, while the remaining plumage is black. It has white crown feathers erected in a crest (hence the common name). Between the eye and the bill and on the throat there is bare dark blue skin. The bill is mainly black, with a yellowish base. Like most hornbills, it has a blackish casque on the top of its bill. The female has a black neck and underparts.

27-5-2023 TABIN RESERVE, BORNEO - MAROON BREASTED PHILENTOMA (Philentoma velata)

The maroon-breasted philentoma (Philentoma velata) is a bird species. They are now usually assigned to the Vangidae. 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 swamps.

It is threatened by habitat loss. 

27-5-2023 TABIN RESERVE, BORNEO - WREATHED HORNBILL (Rhyticeros undulatus)

 The wreathed hornbill (Rhyticeros undulatus) is an Old World tropical bird of the hornbill family Bucerotidae, also called bar-pouched wreathed hornbill due to its distinctive blue-black band on its lower throat sac. It is named after its characteristic long, curved bill that develops ridges, or wreaths, on the casque of the upper mandible in adults. Males are black with a rufous crown, a white upper breast and face, and a yellow featherless throat. Females are uniformly black with a blue throat and are slightly smaller than males.

The wreathed hornbill ranges across the foothills and evergreen forests of Northeast India and Bhutan to Bangladesh, Southeast Asia and the Greater Sunda Islands. It is a frugivore and feeds mainly on large fruits, which it swallows whole leaving the seeds intact. This feeding behaviour plays an important ecological role for the long-distance seed dispersal in forest ecosystems.

The wreathed hornbill is threatened by hunting, habitat fragmentation and deforestation. It has been listed as Vulnerable on the IUCN Red List since 2018, as the global population is estimated to decrease due to these threats.

26-5-2023 TABIN RESERVE, BORNEO - BUSHY CRESTED HORNBILL (Anorrhinus galeritus)

The bushy-crested hornbill (Anorrhinus galeritus) is a bird in the hornbill family. It is found in Brunei, Indonesia, Malaysia, Myanmar, and Thailand. Its natural habitat is subtropical or tropical moist lowland forests.

It lives in groups.

Females have a unique nesting behavior in which they stay alone in a mud-covered tree hole during incubation and are fed by other hornbills from outside the nest.

The bushy-crested hornbill mainly eats fruit: several different species of figs, Indian Mast Tree (Polyalthia lateriflora), Oncosperma horridum, Canarium megalanthum, Canthiumera glabra, Zuccarinia macrophylla, Myristica sp., Horsfieldia sp., champak (Magnolia champaca), Dysoxylum sp., Fibraurea tinctoria, Endocomia macrocoma, and Alseodaphne falcata.

22-5-2023 SAKAU RIVER LODGE, BORNEO - PROBOSCIS MONKEY (Nasalis larvatus)

The proboscis monkey (Nasalis larvatus) or long-nosed monkey is an arboreal Old World monkey with an unusually large nose, a reddish-brown skin color and a long tail. It is endemic to the southeast Asian island of Borneo and is found mostly in mangrove forests and on the coastal areas of the island.

This species co-exists with the Bornean orangutan and monkeys such as the silvery lutung. It belongs in the monotypic genus Nasalis.

24-5-2023 SUKAU RIVER LODGE, BORNEO - BORNEAN ELEPHANT (Elephas maximus ssp. borneensis)

The Borneo elephant, also called the Bornean elephant or the Borneo pygmy elephant, is a subspecies of Asian elephant (Elephas maximus) that inhabits northeastern Borneo, in Indonesia and Malaysia. Its origin remains the subject of debate. A definitive subspecific classification as Elephas maximus borneensis awaits a detailed range-wide morphometric and genetic study. Since 1986, the Asian elephant has been listed as Endangered on the IUCN Red List as the population has declined by at least 50% over the last three generations, estimated to be 60–75 years. It is pre-eminently threatened by loss, degradation and fragmentation of habitat.

The Sultan of Sulu was thought to have introduced captive elephants to Borneo in the 18th century, which were released into the jungle. Comparison of the Borneo elephant population to putative source populations in DNA analysis indicates that the Borneo elephants more likely derived from Sundaic stock and are indigenous to Borneo, rather than having been introduced by humans. The genetic divergence of Borneo elephants warrants their recognition as a separate evolutionarily significant unit.

24-5-2023 SUKAU RIVER LODGE, BORNEO - GRAY HEADED FISH EAGLE (Haliaeetus ichthyaetus)

The grey-headed fish eagle (Icthyophaga ichthyaetus) is a fish-eating bird of prey from South East Asia. It is a large stocky raptor with adults having dark brown upper body, grey head and lighter underbelly and white legs. Juveniles are paler with darker streaking. It is often confused with the lesser fish eagle (Icthyophaga humilis) and the Pallas's fish eagle. The lesser fish eagle is similar in plumage but smaller and the Pallas's fish eagle shares the same habitat and feeding behaviour but is larger with longer wings and darker underparts. Is often called tank eagle in Sri Lanka due to its fondness for irrigation tanks.

24-5-2023 SUKAU RIVER LODGE, BORNEO - VERDITER FLYCATCHER (Eumyias thalassinus)

It is found from the Himalayas through Southeast Asia to Sumatra. This species is named after its distinctive shade of copper-sulphate blue and has a dark patch between the eyes and above the bill base. The adult males are intense blue on all areas of the body, except for the black eye-patch and grey vent. Adult females and sub-adults are lighter blue.

The verditer flycatcher is also interesting among the flycatchers in that they forage above the canopy level and perching on electric wires or exposed tree top branches.

This species was earlier placed in the genus Muscicapa and it has been suggested that it is closer to the Niltava flycatchers.
