Distribution
| Estimate | Data quality | |
|---|---|---|
| Extent of Occurrence breeding/resident (km2) | 599,000 | medium |
| Extent of Occurrence non-breeding (km2) | 1,500,000 | medium |

Population & trend
| Estimate | Data quality | Derivation | Year of estimate | |
|---|---|---|---|---|
| No. of mature individuals | 11000-56000 | medium | Estimated | 2006 |
| Population trend | Decreasing | poor | - | |
| Number of subpopulations | - | - | - | |
| Largest subpopulation | - | - | - | |
| Generation length (yrs) | 5.7 | - | - | - |
| Population justification: The global population is estimated to number c.16,000-84,000 individuals (Morrison et al. 2006). | ||||
| Trend justification: A moderate and on-going decline is suspected based on surveys at staging posts. This is thought to be driven by habitat loss and conversion, but contaminants may also have an impact. | ||||
