Population & trend

  Estimate Data quality Derivation Year of estimate
No. of mature individuals 3300-10000 medium Estimated 1993
Population trend Decreasing poor -

Largest subpopulation 5000-15000 - - -
Generation length (yrs) 7.8 - - -
Population justification: The population is estimated to number 5,000-15,000 individuals, roughly equating to 3,300-10,000 mature individuals.
Trend justification: M. Wondafrash in litt. (2007) indicates from census data that the species is declining at a slow to moderate rate, owing to habitat degradation.
