Sarus Crane

About the sarus crane

The sarus crane is a large, nonmigratory crane found in parts of the Indian subcontinent, Southeast Asia, and northern Australia. It is the tallest of all flying birds, standing up to 1.8 m (5 ft 11 in), and it is a conspicuous presence wherever it lives: open wetlands in South Asia, seasonally flooded Dipterocarpus forests in Southeast Asia, and Eucalyptus-dominated woodlands and grasslands in Australia. The bird is easy to pick out from other cranes in its range thanks to an overall grey body set off by a bright red head and upper neck.

The species was first illustrated for European science in 1743 by the naturalist George Edwards, who called it "The Greater Indian Crane." Carl Linnaeus later placed it with herons and cranes in the genus Ardea, but it was eventually moved, along with three related species, into the resurrected genus Antigone following a 2010 molecular study that found the old genus Grus was not a natural grouping. Most modern authorities recognize a single species made up of three geographically separated populations, sometimes treated as subspecies: the largest, in India, has a white collar below its bare red head and neck and white feathers in its wings; a Southeast Asian population extending from Myanmar lacks this white collar; and an Australian population, first noticed there in 1966 and formally named only in 1988, is distinguished by a larger grey patch of ear coverts. Genetic work suggests all three descend from a formerly continuous population, with Australia colonized roughly 35,000 years ago during the Late Pleistocene — a history that has left the small Australian population with notably low genetic variability. A fourth population once lived in the Philippines, where it was known locally as tipol, but it is now considered extirpated; recent genetic analysis suggests it was more closely related to the Australian birds than to the geographically closer Southeast Asian population.

Adults have grey wings and body, a bare red head, collar, and nape, a greyish crown, and a long, pointed, greenish-grey bill, with orange-red irises and long pink legs that trail behind them in flight. The sexes look alike, though males run larger; males of the Indian population can reach about 180 cm (5.9 ft) in height, the tallest recorded for any living flying bird. Weight varies by population and sex, from around 5 to 12 kg (11 to 26 lb) overall, with Indian-population birds among the heaviest of all cranes and Australian birds running noticeably lighter, at roughly 5.0 to 6.9 kg (11.0 to 15.2 lb) for both sexes combined.

Behavior and diet

Like other cranes, sarus cranes form long-lasting pair bonds and defend territories with loud trumpeting calls, leaps, and dance-like courtship displays. In India, where the species is closely associated with agricultural land and lives in near proximity to people, sarus cranes are traditionally viewed as symbols of marital fidelity, believed by some to mate for life and to grieve a lost partner so deeply that they can starve themselves.

The birds forage in marshes and shallow wetlands, feeding on roots, tubers, insects, crustaceans, and small vertebrate prey. Breeding takes place mainly during the wet season, when a pair builds an unusually large nest: a circular platform of reeds and grasses nearly two meters across and built high enough to stay above the shallow water around it. Sarus cranes are largely sedentary rather than migratory, though the Australian population is partly migratory in some areas.

Range and habitat

Historically, sarus cranes ranged across the lowlands of India along the Gangetic plains, from coastal Gujarat and Pakistan's Tharparkar District east to West Bengal and Assam, though the species no longer breeds in Punjab and has become rare or absent in several eastern Indian states. In Nepal, it survives mainly in the western and central lowland plains. The stronghold of the species today is India, where the largest known population is found in Uttar Pradesh; there, small-holder agriculture, favorable farmer attitudes, flooded rice paddies, and an extensive canal network appear to have actually benefited the birds even as agricultural intensification is often blamed for declines elsewhere. Within Uttar Pradesh, abundance is highest in western districts and rises with the percentage of wetlands on the landscape, but falls where more land is given over to rice cultivation.

Elsewhere, the picture is one of retreat: the sarus crane may now be extinct in Thailand and the Philippines, parts of its former Southeast Asian range, and only remnant populations persist in Myanmar's Ayeyarwadi delta — where more than 150 breeding pairs have been found, along with additional birds in Kachin, Shan, and Rakhine states — and in scattered locations in Cambodia and Vietnam. A 2011 reintroduction effort released 24 captive-bred cranes into Thailand. In Australia, the species occurs only in the northeast, where researchers have proposed it as the best genetic source population for a future attempt to reintroduce sarus cranes to the Philippines.

Conservation status

The sarus crane is listed as Vulnerable on the IUCN Red List, in a 2025 BirdLife International assessment. The global population is estimated at about 16,000 mature birds. The South Asian subspecies is the largest, at about 10,500, while the Southeast Asian subspecies has only 400 to 600 mature individuals and the Australian subspecies likely 3,000 to 5,000.

The global range has shrunk substantially, and the species is already extirpated from large parts of its former territory in Southeast Asia and the Philippines. India holds by far the largest occupied range and population, aided by the country's dense network of irrigated, wet agricultural land, which appears to support rather than harm the population there. That is a contrast with the more typical story of agricultural intensification driving crane declines elsewhere.

In India the sarus crane is traditionally revered and lives on farmland close to people, and favorable farmer attitudes have helped it thrive there, even though many farmers believe the birds damage standing crops.
