"Ornithology is a very dynamic part of the general science of zoology. Entering a new century, we see some old ornithological concepts being swept away, and new ones taking their place. Australia's ecosystems and the birds within them, are continually under threat from long-term drought, and beyond that, land clearance, erosion, salination, pollution and other forms of environmental damage. These are the inevitable result of an increasing human population and our sometimes inappropriate requirements." "The recent severe drought has led to some spectacular movements of birds away from central Australia, often far outside of their 'normal' distribution, and is reflected in new 'spots' on many of the maps." "This book is for furthering the enjoyable and fascinating pastime of birdwatching in all its varied intensities and facets. Our primary aim is to enhance our readers' capabilities in indentifying the birds they may encounter." "It is for everybody, of all ages." - BOOK JACKET
