RSPB Birds: Their Hidden World [EPUB ebook] 

Even if you are an enthusiastic bird watcher, the details of how birds fly, why they behave as they do, how they breed and their extraordinary travels can seem very mysterious.This lively new book aims to give readers a broad understanding of ‘how birds work’ from their physical make-up to courtship and breeding, social activity and their spread and travels. Readers will be able to interpret the kind of bird activity and behaviour that they see and hear in their gardens as well as in the wider countryside and on nature reserves.Designed for the general interest reader and written in a lively and accessible style, the book is presented as a series of beautifully illustrated page spreads, enhanced by fully captioned photographs and with case studies of individual species of British and European birds.
