An up-to-date, fully illustrated monograph on all Australian species of grassfinches.
It is not surprising that Australian grassfinches are highly popular with ornithologists and aviculturists, for included among the species are one of the most beautiful of all birds – the Gouldian Finch Erythrura gouldiae – and one of the most familiar cagebirds – the Zebra Finch Taeniopygia guttata. Despite a scarcity in published works on finches, interest in the species is growing, leading to a dramatic advancement in our knowledge of many species. For example, we have gained new information from field observations carried out on little-known species, including the Blue-faced Parrot-Finch Erythrura trichroa and the Red-eared Firetail Stagonopleura oculata. Significant advances in taxonomic research, largely as a consequence of the development and refinement of biochemical analyses, often involving DNA-DNA hybridisation, have given us a new insight into relationships among species, with some unexpected alliances being determined. Additionally, dramatic changes have taken place in avicultural practices, and in virtually all countries aviculture has taken on a new professional approach, with the most notable results being increased productivity and success with a wider variety of species. After a lapse of almost half a century since publication of Klaus Immelmann’s eminent work on finches, based on extensive field studies, the time has come for a new examination of Australian grassfinches. In Grassfinches in Australia, Joseph Forshaw, Mark Shephard and Anthony Pridham have summarised our present knowledge of each species, and have given readers a visual appreciation of the birds in their natural habitats and in aviculture. The resulting combination of superb artwork and scientifically accurate text ensures that this volume will become the standard reference work on Australian grassfinches. In addition to enabling aviculturists to know more about these finches in the wild as a guide to their own husbandry techniques, detailed information on current management practices for all species in captivity is provided. The book also includes colour plates depicting some of the more common mutations held in Australian and overseas collections.
The popularity of Australian Grassfinches worldwide is largely due to the hardiness of these tiny, gregarious and colourful birds. The 18 members of the Grassfinch family Estrildae recognised in Australia are featured in detail.

Recent classifications of Australian birds have been limited to lists of "species" which are inadequate as biodiversity indicators. The Directory of Australian Birds: Passerines fills a huge gap in ornithological knowledge by separating out and listing not only 340 species of song-birds but also the 720 distinct regional forms. Covering about half the national bird fauna, the Directory provides science and the community with baseline information about what bird it is and where it lives in an Australia-wide context. Identity is taken down to the level of distinct regional population. No other compendium on Australian birds does this.
This is the first book to deal exclusively with the Australian members of the Family Ardeidae (herons, egrets and bitterns). It gives a comprehensive, easy-to-read account of their origins, classification and biology, and explains the features that distinguish them from other birds. The book devotes a major chapter to the 14 Australian species, covering their distribution and movements, feeding, breeding, population dynamics and conservation. Some of Australia’s herons have become very scarce in the southern half of the continent and are at risk of national or local extinction. In northern Australia heron habitats and resources are largely pristine and consequently this region accommodates large numbers of certain species. A final chapter on population and conservation provides a useful summary of the present status of the Australian herons, some of whom are thriving and others who are in a very precarious position.
"In A Taste for the Beautiful, Michael Ryan, one of the world's leading authorities on animal behavior, tells the remarkable story of how he and other scientists have taken up where Darwin left off, transforming our understanding of sexual selection and shedding new light on animal and human behavior. Drawing on cutting-edge science, Ryan explores the key questions: Why do animals perceive certain traits as beautiful and others not? Do animals have an inherent sexual aesthetic and, if so, where is it rooted? Ryan argues that the answers lie in the brain--particularly of females, who act as biological puppeteers, spurring the development of beautiful traits in males."--Back cover
