The text gives concise information on field identification (including voice) and provides details on habitat, altitudinal range, and status. A color distribution map is also given for every species. The 96 plates illustrate all 2,300 species recorded in the region (including a few extralimital birds which may in future occur). Female plumages are included if different from the males, and some juvenile plumages and distinct races are also shown where relevant.
