The black-headed ibis (Threskiornis melanocephalus), also known as the Oriental white ibis, Indian white ibis, and black-necked ibis, is a species of wading bird of the ibis family Threskiornithidae which breeds in the South and Southeast Asia from India to the west and as far east as Japan. [1] [2] It is the only native ibis species in its range that has an overall white plumage with a black neck and head. The down-curved beak and legs are also black. Though often referred to as a wetland species, the black-headed ibis forages in a range of natural and man-made habitats. [3] This species of ibis nests only during the rainy season.

Description

The black-headed ibis is one of several large waterbird species in south and south-east Asia, with adults measuring 65–76 cm in length. [4] The white plumage is starkly contrasted against a conspicuous naked black neck and head, and black down-curved beak. Tails of adults bear light grey ornamental feathers that turn jet black during the breeding season. During the breeding season, bare patches under the wing turn blood-red. The head of some breeding adults gain a blueish tinge, or very rarely have a pink or bright red patch behind the neck. [5] [6] Some breeding adults also develop tufts of white feathers behind the neck, and rarely also get a yellowish colouration on the breast and back. Sexes are identical but juveniles are identifiable from adults in having greyish feathering on the neck and speckled brown-grey feathering on the wings and back. Like storks and spoonbills, it lacks a true voice-producing mechanism and is silent except for ventriloquistic grunts uttered by pairs at the nest. [4]

Distribution and habitat

Black-headed ibis are native to the following countries: Bangladesh, Cambodia, China, Hong Kong, India, Indonesia, Malaysia, Myanmar, Nepal, Pakistan, Philippines, Russian Federation, Sri Lanka, Thailand and Vietnam. They are migratory or vagrant in Japan, Republic of Korea, Lao People's Democratic Republic and Mongolia. [1] The species is a widespread breeding bird in India, Sri Lanka, Nepal and Myanmar, and has declined considerably to few locations or breeding colonies in Cambodia, Indonesia, Malaysia, Thailand, and Vietnam. The most rapid decline in recent times is suspected to be the population in Sumatra. [7]

The black-headed ibis is very versatile being able to use a large variety of natural and man-made habitats. These include freshwater and salt-water marshes, lakes and ponds, as also rice fields, freshly ploughed crop fields, irrigation canals, riversides, reservoirs, urban lakes, open sewage gutters, grazing lots, and garbage dumping sites. [5] [8] [9] [3] Ibis alter use of varied preferred foraging habitats by season in agricultural landscapes such as in south-western Uttar Pradesh in India. In summer, they largely use and prefer natural marshes and fallow fields, but in the monsoon, spread out more evenly to also use a variety of agricultural fields. [3] In more urban landscapes, Black=headed Ibis abundances were positively associated with crop fields, wetlands and open areas. [10] that have more forests and rocky hills as in southern Rajasthan, wetlands are the preferred habitats year-round and there is little difference in habitats used in different seasons. [8] [11] Inside a town, however, many more ibises were seen in Open sewage lines are used more during the dry summers, and ibis increase the use of grazing lands during the monsoon.

It nests in heronry colonies near wetlands. It builds a platform nest of sticks, lined with grass and threads. [9] Old trees in cities are used for night roosting and for nesting. [12] [13]

The daily activity budget of Black-headed Ibis in a protected wetland showed ibises to spend the maximum time feeding (48%), followed by resting (23%). [14]

It also occurs in the scientific name of the western cattle egret mistakenly identified in 1757 as being the sacred ibis.

<span class="mw-page-title-main">American white ibis</span> Bird in the ibis family

The American white ibis is a species of bird in the ibis family, Threskiornithidae. It is found from Virginia via the Gulf Coast of the United States south through most of the coastal New World tropics. This particular ibis is a medium-sized bird with an overall white plumage, bright red-orange down-curved bill and long legs, and black wing tips that are usually only visible in flight. Males are larger and have longer bills than females. The breeding range runs along the Gulf and Atlantic Coast, and the coasts of Mexico and Central America. Outside the breeding period, the range extends further inland in North America and also includes the Caribbean. It is also found along the northwestern South American coastline in Colombia and Venezuela. Populations in central Venezuela overlap and interbreed with the scarlet ibis. The two have been classified by some authorities as a single species.

<span class="mw-page-title-main">Australian white ibis</span> Species of bird

The Australian white ibis is a wading bird of the ibis family, Threskiornithidae. It is widespread across much of Australia. It has a predominantly white plumage with a bare, black head, long downcurved bill, and black legs. While it is closely related to the African sacred ibis, the Australian white ibis is a native Australian bird. Contrary to urban myth, it is not a feral species introduced to Australia by people, and it does not come from Egypt.

<span class="mw-page-title-main">Heron</span> Family of birds

Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera Botaurus and Ixobrychus are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus Zebrilus, form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks.

<span class="mw-page-title-main">Black-necked stork</span> Species of bird

The black-necked stork is a tall long-necked wading bird in the stork family. It is a resident species across the Indian Subcontinent and Southeast Asia with a disjunct population in Australia. It lives in wetland habitats and near fields of certain crops such as rice and wheat where it forages for a wide range of animal prey. Adult birds of both sexes have a heavy bill and are patterned in white and irridescent blacks, but the sexes differ in the colour of the iris with females sporting yellow irises and males having dark-coloured irises. In Australia, it is known as a jabiru although that name refers to a stork species found in the Americas. It is one of the few storks that are strongly territorial when feeding and breeding.

<span class="mw-page-title-main">Painted stork</span> Species of bird

The painted stork is a large wader in the stork family. It is found in the wetlands of the plains of tropical Asia south of the Himalayas in the Indian Subcontinent and extending into Southeast Asia. Their distinctive pink tertial feathers of the adults give them their name. They forage in flocks in shallow waters along rivers or lakes. They immerse their half open beaks in water and sweep them from side to side and snap up their prey of small fish that are sensed by touch. As they wade along they also stir the water with their feet to flush hiding fish. They nest colonially in trees, often along with other waterbirds. The only sounds they produce are weak moans or bill clattering at the nest. They are not migratory and only make short-distance movements in some parts of their range in response to changes in weather or food availability or for breeding. Like other storks, they are often seen soaring on thermals.

<span class="mw-page-title-main">Asian openbill</span> Species of bird

The Asian openbill or Asian openbill stork is a large wading bird in the stork family Ciconiidae. This distinctive stork is found mainly in the Indian subcontinent and Southeast Asia. It is greyish or white with glossy black wings and tail and the adults have a gap between the arched upper mandible and recurved lower mandible. Young birds are born without this gap which is thought to be an adaptation that aids in the handling of snails, their main prey. Although resident within their range, they make long distance movements in response to weather and food availability.

The white-necked heron or Pacific heron is a species of heron that is found on most of the Australian continent wherever freshwater habitats exist. It is also found in parts of Indonesia and New Guinea, but is uncommon in Tasmania. The populations of this species in Australia are known to be nomadic like most water birds in Australia, moving from one water source to another, often entering habitats they have not previously occupied, taking advantage of flooding and heavy rain where the surplus of food allows them to breed and raise their young. Irruptive movements may occur when environmental conditions are right in places where the species has been rare or absent.
