The Sarus crane is the world's
tallest flying bird; a large male may stand six feet tall. There are three
recognized subspecies of the sarus crane. The Indian sarus cranes live, as their
name implies, predominately in Asia's subcontinent. In areas dominated by the
Hindu religion, the Indian sarus suffers little persecution. They have, as a
result, lost much of their fear of humans and often nest in rice paddies where
they are regarded as omens for good crops, especially in India.
Eastern
sarus cranes were once abundant in Southeast Asia, but after decades of war they
are missing from most of their former range. The few that remain nest in
Cambodia in small wetlands surrounded by dry forest, but migrate to Viet Nam's
lower Mekong Delta to winter at the Tram Chim National Reserve. There is a
smaller non-migratory population, discovered by ICF staff in 1996, that lives in
Myanmar's Irrawaddy delta. The third subspecies is the Australian sarus crane.
HabitatNorthern and central India, southeastern Pakistan,
southern Myanmar, Cambodia, southern Laos, Viet Nam, and northern Australia. The
Philippine population of sarus cranes is probably extinct.
StatusDespite cultural and religious protections, sarus
cranes are vulnerable in most areas. Roughly 8,000 to 10,000 Indian sarus
remain, though the population is declining due to the loss of wetlands and
increasing amounts of pollution as the human population continues to grow. The
greatest concentration of Indian sarus cranes occur where land use practices
have changed little
from
traditional patterns. Some fear that the whole wetland food web on which sarus
cranes depend may be under stress as pesticides and fertilizers become more
widespread in the subcontinent's rural areas. Even in India's Keoladeo National
Park, the number of sarus nests has decreased since the early 1980s.
The
Eastern sarus population in Southeast Asia is estimated at 500 to 1,500 birds.
This subspecies is subject to hunting, pollution, warfare, heavy use of
pesticides, and development of the Mekong River. A rapidly growing human
population threatens to overwhelm areas that these cranes rely on. There is also
trade in and hunting of both chicks and adult birds in some areas.
