Ornithology, Birdwatching 

This new edition of "Sasol Birds" is larger in both size and extent; a new section deals with the identification of "problem species", or those which are difficult to tell apart. Intended for use in the field, the text is pitched at a level to appeal to beginners, although the detail suggests it may also be of interest to more serious and professional birdwatchers. Each species account provides the bird's common name in English and Afrikaans; its scientific name; its Roberts number and its length; key points to look for when identifying the species; plumage descriptions of the male, female and immature, breeding and non-breeding birds where applicable; and typical behaviour, voice, habitat, nests and food. Distribution information is shown by means of a colour map, and the whole book is colour-coded according to the different bird groups. - from Amzon
