The site was identified as important in 2004 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.
Populations meeting IBA criteria ('trigger species'):Species | Current IUCN Red List Category | Season | Year(s) | Population estimate at site | IBA criteria met |
---|---|---|---|---|---|
Nicobar Scrubfowl Megapodius nicobariensis | VU | resident | 2004 | present | A1, A2 |
Andaman Woodpigeon Columba palumboides | NT | resident | 2004 | present | A2 |
Andaman Cuckoo-dove Macropygia rufipennis | LC | resident | 2004 | present | A2 |
Andaman Boobook Ninox affinis | LC | resident | 2004 | present | A2 |
Nicobar Sparrowhawk Accipiter butleri | VU | resident | 2004 | present | A1, A2 |
Nicobar Bulbul Ixos nicobariensis | NT | resident | 2004 | present | A1, A2 |
White-headed Starling Sturnia erythropygia | LC | resident | 2004 | present | A2 |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (2004).
