Ornithology, the study of birds, has a long and rich history. Studies and observations on birds have been instrumental in developing theories within the fields of ecology, ethology and evolutionary biology (e.g. Darwin's finches on the Galápagos islands). You will find a wide selection of scientific books on bird biology and conservation here.
Birdwatching, or twitching, has become a popular pastime, and we list a wide range of field guides to destinations around the globe, both photographic or with illustrated plates. That birdwatching can be addictive can be seen from the many books we list from authors who have gone to great lengths to observe as many species as they can.
This section furthermore contains reference works, such as Lynx's famous Handbook of he Birds of the World, species monographs, distribution atlases, world lists, and guides to birdwatching sites.
