Black-Headed Ibis Decline Alarms Naxalbari Conservationists
Black-headed ibises are birds that visit Naxalbari each year.
They help control pests in nearby rice fields.
Their numbers have fallen from about 350 to around 190.
Experts say the birds are losing wetlands, rice fields and plants where they find food.
Some large trees used for breeding have also been cut down or disappeared.
The birds usually come in March and leave in early October.
Volunteers and forest officials count the adult breeding birds each year.
They say protecting the remaining wetlands, fields and trees could help the birds.
Annual counts in Naxalbari found about 190 black-headed ibises this year, down from roughly 350 in previous years.
Conservationists and foresters link the decline to disappearing wetlands, paddy fields, vegetation and breeding trees.
The birds have been sighted in Naxalbari for more than 25 years, reportedly only in this north Bengal location.
Black-headed ibises usually arrive in March and remain until the first week of October.
The species is classified as Near Threatened by the International Union for Conservation of Nature.

“The black-headed ibis has been sighted in Naxalbari, around 25km from Siliguri, for more than two decades. But our annual count shows that its numbers are declining rapidly, largely because of the loss of water bodies and increasing urbanisation”
