This, the 6th volume in a set of seven, follows the standard taxonomic sequence and deals with songbirds from the babblers to the starlings. A new introduction brings the reader up to date with recent developments in the series and includes an essay on aspects of biogeography illustrated through African birds. Overviews of the families are followed by genus summaries (with associated superspecies maps, where appropriate) and the species accounts themselves, organised under standard headings: range and status, description, field characters, voice, general habits, food, breeding habits, and key references. Each species has a distribution map and many are illustrated with line drawings showing nests and behaviour.
