Conservation agencies (Brown 1992).
The Bearded Vulture was located in 92 1/4 ° 1/4 by grid-cells (i.e. 2% of all of southern
Africa) during the Southern African Bird Atlas Programme (SABAP) and this gives a total
distributional range of 60,205 km 2 , although this author claimed that this deme’s range was
100,000 km 2 (Brown 1997a). These data from SABAP were collected, in the main, in the five
year period 1988 to 1992, both years inclusive (Harrison, Allan, Underhill, Herremans, Tree,
Parker and Brown 1997), though for KwaZulu-Natal, the earlier data collected between 1970
and 1979, both years inclusive, for the Bird Atlas of Natal (Cyrus and Robson 1980) were also
incorporated. Within this range there were 858 records of Bearded Vulture giving an average
