The species predicted range is of 2500 – 5000 km2 (Ágreda et al. unpub.). Calculations of population size used population estimates of 0.9 – 1.8 individuals per km2 (Birdlife International 2008) resulting in an estimate global population size of c. 2000 – 4000 individuals (Ágreda et al. unpub.).

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