| Land mass type | Average mass | - |
Distribution
| Estimate | Data quality | |
|---|---|---|
| Extent of Occurrence breeding/resident (km2) | 19,700 | medium |

Population & trend
| Estimate | Data quality | Derivation | Year of estimate | |
|---|---|---|---|---|
| No. of mature individuals | 10000 | poor | Estimated | 2000 |
| Population trend | Decreasing | poor | - | |
