Hornbills of the World
by P Poonswad & A Kemp
Hornbills (order: Bucerotiformes) are a group of distinctive and charismatic birds found only in Tropical Asia and sub-saharan Africa. There are two families (bucorvidae and bucerotidae), 15 genera, 57 species and 75 subspecies; 32 species are in Asia and 25 species in Africa. They are mostly large in size and have long bills surmounted in many species by a conspicuous casque.
Hornbills of the World is the first authoritative photographic guide to the order. All species are described and illustrated in multiple photographs showing both male and female, and distinct subspecies. There is additional information on Evolution, Distribution and Relationships, General Habits, Feeding Ecology, Breeding Ecology, Social Life, Threats and Conservation.
