Australian High Country Owls provides the latest scientific information on Australian owl species, especially Ninox owls. It details studies of Southern Boobooks and Powerful Owls, visits to North America and Europe to learn about owl research, and the resulting publications that overturned some existing beliefs about Australian owls. Ultimately, this led to the discovery of a new owl species in Indonesia, the Little Sumba Hawk-Owl.
Appendices cover the biology, conservation and rehabilitation of Australian owls, including: field recognition, subspecies taxonomy, habitat, behaviour, food, range, migration, breeding, voice and calls, status and myths, questions about each species, and techniques for caring for injured and orphaned owls.
The book includes numerous photographs of different owl species, and will be a handy reference for bird researchers and amateur bird watchers alike.
