A team of bird watchers and researchers who conducted an annual water fowl census in Tumariya Wetlands near the Corbett National Park in Uttarakhand has reported the first sighting in the state of a highly unusual winter migrant to India a lone Bean Goose.
The Bean Goose,known by the scientific name Anser Fabalis,breeds in the Arctic regions and is known to have been sighted in the Indian subcontinent only twice before,in 2003 and 2007,according to the researchers from the Corbett Foundation,a conservation group working in the area that sighted the species.
A single Bean Goose was sighted among a flock of species like the Bar-headed Goose and Ruddy Shelduck,which are common winter migrants to the Corbett landscape on December 1,2011. Once we were sure that it was a Bean Goose,we consulted other experts including the Goose Specialist Group of the Wetlands International and IUCN species survival commission. We heard from them in March with a confirmation that the bird sighted was a Bean Goose, said Anushree Bhattacharjee,who headed the team of five researchers.
The Bean Goose has two varieties the Tundra Bean Goose and the Taiga Bean Goose.
The one sighted in Tumariya was confirmed as Tundra Bean Goose by experts of the Goose Specialist group,she said.
The species travels south during winter months in the Artic to temperate and sub-tropical regions in Europe as well as Asia. The range of the species usually extends only as far south as China,she said.
