Book excerpt: This volume is dedicated to the field identification of pigeons and doves, and it incorporates much recent information on the family. Pigeons and doves are a large family of birds occurring throughout the world. Many species are specialist frugivores, while others feed on seeds. Most are arboral and the tropical species in particular are often brightly coloured. The family includes gregarious migratory species, as well as shy, ground-dwelling forms such as the exotic crowned pigeons of New Guinea.
