Sasol Voëls van Suider-Afrika is een van die gewildste veldgidse oor die voels van Suider-Afrika. Kort beskrywings (met die Robertsnommer van die spesie), verspreidingskaarte en duidelike sketse gee aan voëlkykers riglyne oor die uitkenning van voëlspesies in die veld. By die illustrasies is kriptiese aantekeninge oor onderskeidende kenmerke om die voëlkyker help met identifikasie.

SASOL Birds of Southern Africa: Checklist & Alternative Names, compiled by P.A.R. Hockey. This slim companion volume to the Sasol guide, which is also cross-referenced to Sinclair, Newman and Roberts, is very handy for keeping a list of birds seen in the southern African sub-continent. Unfortunately its abundance scale - a system of small, intermediate and large dots denoting the relative ease with which a particular species can be seen in any month - suffers from the dots being confusingly similarly sized. One of the book's best features is a section containing alternative names. T
