Population justification: The paucity of atlas records strongly suggests that it is far rarer than previously thought, and probably numbers c.2,500 individuals. Some of the atlas data may, however, be misleading as the area between Durban and East London in the former Transkei was not well covered, giving the impression of a discontinuous distribution (N. Smith in litt. 2007), thus it is probably best placed in the band 2,500-9,999 mature individuals. This estimate equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals. |
|
Trend justification: This species's population is suspected to be declining in line with habitat loss and degradation within its range. The likely rate of decline, however, has not been estimated. |
