Demography and Populations

The population size is estimated at <100,000 individuals across its range, but requires further research to make it more accurate (Ellis-Joseph et al. 1992). The population is believed to be decreasing (Rose and Scott 1997, BirdLife International 2010).

There is no information related to topics such age at first breeding, life span and survivorship, dispersal, or population regulation.
