Ephippiorhynchus-asiaticus-02-800

The Black-neckeEphippiorhynchus asiaticus, Black-necked Stork,  Bangau Leher-hitamd Stork, Ephippiorhynchus asiaticus is a large wading bird in the stork family Ciconiidae. It is a widespread species, which is a resident breeder in southern Asia and Australasia, from India east to New Guinea and the northern half of Australia. In Australia, it is also given the common name Jabiru in Australia. Despite similarities in appearance, the stork of this name in the Americas belongs to a different genus.
The Black-necked Stork is a quite large bird, typically 130-150 cm (51-60 inches) tall with a 230 cm (91 inches) wingspan. The average weight is around 4100 grams. It is spectacularly plumaged. The head, neck, wing bar and tail are jet black, with the rest of the plumage white. The massive bill is black and the legs are bright red. Sexes are identical except that the female has a yellow iris, while the male’s is brown. Juveniles are mainly light brown with a white belly and dark legs.

Like most storks, the Black-necked Stork flies with the neck outstretched, not retracted like a heron.

The Black-necked Stork breeds in marshes and other wetlands in tropical lowland. It builds a stick nest in trees, laying three to five eggs. It often forms small colonies. The diet consists mainly of fish, frogs and large insects. Small mammals, reptiles and small birds are also taken. The Black-necked Storks are extremely sensitive to environmental changes like water pollution, habitat destruction and human disruption around breeding sites. It is evaluated as Near Threatened on the IUCN Red List of Threatened Species and Endangered in the Australian state of New South Wales at the southern tip of its range.
Range

It is a widespread species, which is a resident breeder in southern Asia and Australasia, from India east to New Guinea and the northern half of Australia.

Egretta-intermedia-02-800

The Intermediate Egret or MeEgretta intermedia,  Intermediate Egret, Kuntul Perakdian, or Yellow-billed, Egret, (Ardea intermedia) is a medium-sized heron. It is a resident breeder from east Africa across tropical southern Asia to Australia. It often nests in colonies with other herons, usually on platforms of sticks in trees or shrubs. Two to five eggs are laid, the clutch size varying with region. This species, as its scientific name implies, is intermediate in size between the Great Egret and smaller white egrets like the Little Egret and Cattle Egret, though nearer to Little than Great. It is about 90 cm tall with all-white plumage, generally dark legs and a thickish yellow bill. Breeding birds may have a reddish or black bill, greenish yellow gape skin, loose filamentous plumes on their breast and back, and dull yellow or pink on their upper legs (regional variations). The sexes are similar.

The Intermediate Egret stalks its prey methodically in shallow coastal or fresh water, including flooded fields. It eats fish, frogs, crustaceans and insects.

Difference from Great Egret

The non-breeding colours are similar, but the Intermediate is smaller, with neck length a little less than body length, a slightly domed head, and a shorter, thicker bill. The Great Egret has a noticeable kink near the middle of its neck, and the top of its longer bill nearly aligns with the flat top of its head. Close up, the bare skin of the Great Egret’s gape line extends in a dagger shape behind the eye, while the Intermediate’s is less pointed and ends below the eye. The Intermediate tends to stalk upright with neck extended forward. The Great is more patient, often adopting a sideways-leaning “one-eyed” stance.

Difference from Little Egret

Little Egrets have yellow-soled feet. They often run after fish in shallow water. Breeding birds have long nuptial plumes on the back of their heads.

Egretta-garzetta-nigripes-02-800

The Little EgretEgretta-garzetta-nigripes--02is the smallest and most common egret in Indonesia Little Egrets eat a wide variety of prey from fish, molluscs and worms to insects and even small mammals and birds.

Little Egrets are the liveliest hunters among herons and egrets, with a wide variety of techniques. They may patiently stalk prey in shallow waters. Or stand on one leg and stir the mud with the other to scare up prey. Or better yet, stand on one leg and wave the other bright yellow foot over the water surface to lure aquatic prey into range. In peninsular Malaysia, some have been observed hunting near floating vegetation (like palm fronds), possibly looking for prey attracted to the shade. They may crouch with their wings slightly outstretched, either to reduce the sun’s glare or perhaps to create shade to attract underwater prey. They may also enthusiastically rush around in shallow waters perhaps to flush out prey. Little Egrets usually hunt alone. Where they hunt in a group, they are well spaced out, each individual aggressively defending a feeding spot. However, they roost communally, often with other herons and egrets, usually in mangroves. They also roost in reedbeds or snags over open water.

Breeding: Little Egrets breed
 in the warm-temperate areas of the Old World, as well as tropical areas like Java, Bali and Kalimantan. They build rough nests out of sticks. A wide variety of nesting sites are used, from trees and bushes to rocks, walls and even on the ground. Up to 5 greenish-blue eggs are laid.

Migration: Little Egrets spend winter in Southeast Asia, migrating in large dispersal flocks, arriving mainly in September-October. Their preferred wintering grounds are mangroves where there are mudflats suited to their hunting style and providing preferred roosting sites. Some may stay in their wintering grounds over the summer.

Status and threats: Like other egrets with beautiful breeding plumes, Little Egrets were threatened by hunting for their feathers .Now, they are more threatened by habitat destruction and pollution. The overuse of pesticides has made them scarce in rice fields.

Egretta eulophotes

Egretta-eulophotes

The ChinEgretta eulophotes, Chinese Egret, Kuntul Chinaese Egret or Swinhoe’s Egret, Egretta eulophotes, is a full-crested, white egret with yellow bill. It breeds in Russia, North Korea, South Korea and mainland China, and then migrates south through Japan, the Philippines, Malaysia, Singapore and Indonesia. The main wintering grounds appear to be in the Eastern Visayas (Leyte, Bohol and Cebu).

It is classified as Vulnerable, the biggest threat being habitat loss. The current population is estimated at between 2,600 and 3,400 birds.

Ardea-sumatrana-01-800

The Great-billed Heron, Ardea sumatrana is a wading bird of the heron family, Ardeidae, resident from southeast Asia to Papua New Guinea and Australia. Its habitats are largely coastal such as islands, coral reefs, mangroves, large rivers. However, occasionally, it can be found inland in shallow ponds.

It feeds in shallow water, spearing fish with its long, sharp bill. It will wait motionless for prey, or slowly stalk its victim.

The Great-billed Heron is a large bird, standing 115cm tall. It is larger than the Purple Heron, which it resembles in appearance, although it is larger and darker. The plumage is largely dark grey above. In flight, it has a uniform dark grey upperwing.

The flight is slow, with its neck retracted. This is characteristic of herons and bitterns, and distinguishes them from storks, cranes and spoonbills, which extend their necks.

Widespread throughout its large range, the Great-billed Heron is evaluated as Least Concern on the IUCN Red List of Threatened Species.
