Population justification: The global population has been estimated at 56,000-81,000 individuals. However, given the estimated rates of power line collisions since this estimate, the true population size is likely to be much lower; a full population census is underway to accurately establish current numbers (J. Shaw in litt. 2012).
Trend justification: Based on collision rates with power lines from two areas, the best-case scenario indicates a decline of 51% over three generations in South Africa, which holds 50-75% of the global population (Jenkins et al. 2011). Given that power lines collisions also occur in Nambia (A. Scott and M. Scott in litt. 2010), and effective mitigation measures are yet to be implemented, a decline of 50-79% is estimated over the 31 year period from 1994-2025 (three generations).
