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. 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. This species of ibis nests only during the rainy season.
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. 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. Some breeding... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-headed Ibis sighting in Sundarbans National Park on a given day, based on 37 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 117th most-seen of the 177 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
March and December
In those months about 10% of wildlife watchers report a Black-headed Ibis in Sundarbans National Park on a given day, against under 5% in January–February, April and July–November, the lowest months. Those are among Sundarbans National Park's driest months, with about 40 mm of rain a month against 480 mm in July. May and June have too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Black-headed Ibis sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
13th of 19
Of the 19 parks where we can rate Black-headed Ibis sightings, Sundarbans National Park ranks 13th at under 5%. The best odds are in Keoladeo National Park (India, about 70%), Yala National Park (Sri Lanka, about 70%) and Kaziranga National Park (India, about 60%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Black-headed Ibis is recorded against all the birds logged in Sundarbans National Park (37 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
