دانلود کتاب Australasian Eagles and Eagle-like Birds

An illustrated record of sea-eagles, harpy eagles, booted eagles and eagle-like hawks in Australasia. Eagles are awe-inspiring birds that have influenced much human endeavour. Australia is home to three eagle species, and in Melanesia there are four additional endemic species. A further three large Australian hawks are eagle-like. Eagles, being at the top of the food chain, are sensitive ecological barometers of human impact on the Earth's ecosystem services, and all of the six Australian species covered in this book are threatened in at least some states (one also nationally). Three of the four Melanesian tropical forest endemics are threatened or near-threatened. In Australasian Eagles and Eagle-like Birds, Dr Stephen Debus provides a 25-year update of knowledge on these 10 species as a supplement to the Handbook of Australian, New Zealand and Antarctic Birds (HANZAB) and recent global treatises, based partly on his own field studies. Included are the first nest or prey records for some Melanesian species. This book places the Australasian species in their regional and global context, reviews their population status and threats, provides new information on their ecology, and suggests what needs to be done in order to ensure the future of these magnificent birds. Australasian Eagles and Eagle-like Birds is an invaluable resource for raptor biologists, birdwatchers, wildlife rescuers and carers, raptor rehabilitators and zookeepers.
