Estimate Data quality Derivation Year of estimate
Population size unknown poor estimated 2009
Population trend stable - suspected -
Generation length 10.6 years - - -

Population justification: The population is estimated to number 1,200,000 individuals.

Trend justification: The population is suspected to be fluctuating owing to fluctuations in climatic conditions and, consequently, in the abundance of prey populations.
