 Great Nicobar Crake


Phylum: Chordata
Class:Aves
Order:Gruiformes
Family:Rallidae
Genus:Rallina
Species: (not yet named)

A team of scientists of Zoological Survey of India here are presently inventorizing the fauna communities of Great Nicobar Biosphere Reserve (GNBR) under the man and biosphere programme of UNESCO with the sponsorship of Ministry of Environment and Forests, Government of India.The GNBR is one the 17 biosphere reserves designed in India.For the convenience of the future study, this species has been named as ‘Great Nicobar Crake’.

According to the ZSI Scientists, the species under Rallina is a very rare and data deficient group of bird, according to IUCN status. So far 8 species under the genus Rallina have been reported from Australian and Asian continents. Among them 3 species were sighted from India including A&N Islands of which Andaman Crake Rallina canningi is endemic to Andaman.

Presently discovered Rallina is fast running and flightless bird found near water bodies. The bill is rather thick and short, neck moderately long, legs rather heavy with moderate length toes and short claws, and the tail fairly short.The iris is bright red, fleshy eye-ring orange-red; bill entirely very pale green except for slightly reddish-tinged tip, tarsi bright orange-red with duskier claws. No other species of Rallina has a combination of pale green bill, broadly black banded under parts, and heavy orange-red legs.

Presently discovered bird not only enhances the total number of bird species reported from Andaman and Nicobar Islands but also at global level.In 2006, an amateur bird watcher discovered a species, a kind of strikingly coloured babbler being named Bugun liocichla, from the remote parts of Arunachal Pradesh. Till now, that was the only new bird species finding in free India.The discovery is published in a British scientific journal, Birding ASIA.
