"Falcons are stunning and iconic birds. Australia has six falcon species, with two endemic to the continent and two others endemic to the Australasian region. They are important indicators of the health of our ecosystems, due to their position at the top of the food chain. But several species are declining, with two species threatened in some states. In "Australian Falcons: Ecology, Behaviour and Conservation", Dr Stephen Debus provides a 30-year update of knowledge on these six species, as well as a falcon-like hawk, the Black-shouldered Kite. This book is based partly on the author's field studies, as well as being a supplement to the "Handbook of Australian, New Zealand and Antarctic Birds" (HANZAB) and recent global treatises. It offers up-to-date information on the Australian species, including their behaviours, ecology and biology. It reviews their population status and threats, and suggests what needs to be done to ensure the future of these spectacular birds."Australian Falcons" is an invaluable resource for raptor biologists, birdwatchers, wildlife rescuers and carers, raptor rehabilitators and zookeepers"--Publisher's description.

This book is an illustrated field guide to diurnal raptors, a bird group that many people find among the most difficult birds to identify. Raptors are popular and iconic birds, and important ecologically as well as in legislation, with some species listed as threatened. Birds of Prey of Australia will enable people to more easily identify them. It also provides a brief overview of the biology of raptors and an indication of the current state of knowledge on them. The book has been completely revised and updated, with 15 years of new data, a section on difficult species-pairs (split-images providing direct contrast), and rearranged in modern field-guide format, making it easy to use and enabling rapid identification of 'difficult' raptors. Birds of Prey of Australia will appeal to a wide range of readers, including ornithologists, raptor biologists, birdwatchers, wildlife rescuers/carers, raptor rehabilitators, zookeepers, naturalists, bushwalkers, ecological consultants, fauna authorities, park rangers, state forestry personnel and students. 2013 Whitley Award Commendation for Vertebrate Guide.
