ather even distribution using 1-3 habitats. Based on a total of 339 assessments of
predicted habitat preference, red sand and dunes were the richest and most distinctive
habitat, predicted to be used by 102 (62%) for the expected species. Grassy plains are
preferred by an estimated 83 species (51%), with 77 species (47%) in the bare washes
and pans and 66 species (40%) on the rocky mountains and their gravel bases. The 11
aerial-feeding species are included within the above analysis, not for all the habitats they
range across when feeding, but only for the terrestrial habitats some might use for
breeding. Overall, the different habitats attracted a more similar number of bird species
than in more mesic areas, with red sand/dunes only 1.55 more attractive than the least
attractive mountains (and the other plain and pan habitats only slightly more attractive)..
Table 2: Bird species diversity observed and expected on and around Portion 3 of the
farm Zuurwater 62 near Aggeneys, Northern Cape (2918BC). Based on the national list
and annotations of Birdlife South Africa (2011), sorted in the order of ‘Roberts VII’
(Hockey et al., 2005), with probability of occurrence and habitat preferences assessed
after a site visit on 27-28 June 2011.
