Population justification: Based on remote sensing and population density data, the global population has been estimated to number 26,000-550,000 individuals. This figure is revised from 260,000-550,000 individuals, as in many countries extrapolation from forest cover exceeds population numbers that appear reasonable based on anecdotal information about the abundance of the species, as large tracts which are classified as forest in remote sensing data are not occupied by the species (e.g. heath forest).
Trend justification: The species is estimated to have declined by 40-75% over the last 3 generations, using different calculated generation lengths and declines in forest cover. However, given that there is uncertainty in extrapolating population density trends over such a large range, and the data on forest cover trends used was crude, a decline of 30-49% over the past 20 years (3 generations) seems appropriate (Lammertink et al. 2009).
