Migratory status	full migrant	Forest dependency	does not normally occur in forest
Land-mass type		Average mass	-

	Estimate	Data quality
Extent of Occurrence (breeding/resident)	135,000,000 km2	medium
Extent of Occurrence (non-breeding)	133,000,000 km2	medium

Population justification: Brooke (2004) estimated the global population to number around 50,000,000 individuals.

Trend justification: The population is suspected to be in decline as a result of predation by invasive species.
