Population justification: The estimates provided for some known populations (guttata 400-800 pairs; fischeri c.200 pairs; belcheri 30-40 pairs) suggest that the world population numbers less than 2,500 individuals, therefore it is placed in the range bracket for 1,000-2,499 individuals. This equates to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals. |
|
Trend justification: This species's population is suspected to be declining in line with habitat loss and degradation within its range. Surveys of Kenyan coastal forest in 2003 suggest that the species may have undergone very rapid declines since the 1980s (Ndang'ang'a et al. 2008). The likely overall rate of decline, however, has not been estimated. |
