This guide covers all 110 of the world's species of tits, nuthatches and creepers. The Parulidae (true tits), Remizidae (penduline tits) and Aegithalidae (long-tailed tits) form the bulk of the book (78 species), with a further 24 species of nuthatch and eight creepers. The text covers each species under a number of headings: identification, sex and age, voice, distribution and movements, habitat, population, habits, breeding biology, description, movements, geographical variation, relationships, and references. Simon Harrap is co-author of Birdwatching in Britain, and co-author of the forthcoming Helm Identification Guides to Robins and Chats and Thrushes.
