The site was identified as important in 1999 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 |
---|---|---|---|---|---|
Grey-crested Helmetshrike Prionops poliolophus | NT | resident | 1999 | present | A1, A2 |
Red-throated Tit Melaniparus fringillinus | LC | resident | 1999 | present | A1 |
Hunter's Cisticola Cisticola hunteri | LC | resident | 1999 | present | A2 |
Jackson's Widowbird Euplectes jacksoni | NT | resident | 1999 | present | A1, A2 |
The current IUCN Red List category may differ from that which was valid at the time of IBA criteria assessment (1999).
