This is the second edition of the already standard field guide first published in 2009 and reviewed in Bull. ABC 16: 243 - 244. It is broadly the same work, but some significant modifications have been made. Strangely, the book itself gives almost no indication of what these are, but by searching the internet (notably www.nhbs.co.uk) I found that: six plates of estrildids and that of the 'large white-headed gulls' have been replaced, there are more than 20 other new or replaced images, as well as many minor amendments to others; many maps have been modified slightly, especially to show range in Somalia, and all have been improved to make them clearer; many text corrections have been incorporated; three vagrants have been added, and there is now an annotated distribution checklist. In all, an additional 16 pages compared to the first edition!
