A new bird species has been found in India, the first time such a discovery has been made here in more than 50 years, an astronomer and keen bird watcher said on September 12, 2006.

The multicoloured bird, Bugun Liocichla, scientifically known as Liocichla bugunorum, a kind of babbler, was spotted in May in the remote Eaglenest Wildlife Sanctuary (placemarked) in India's northeastern state of Arunachal Pradesh near the border with China, said Ramana Athreya, a member of Mumbai's Natural History Society.
Athreya, who found the bird, named it after the Bugun tribe, which lives in the area.

Athreya caught two of the species, but released them after making detailed notes and taking photographs.
Athreya wrote a paper which was circulated among foreign and Indian experts, who then verified the Bugun Liocichlas as a new species and the International Commission on Zoological Nomenclature approved the name.
