"Parrots comprise one of the most endangered groups of birds, with a growing number of species nearing extinction. The purpose of this book is to bring together information on species that have become extinct in historical times with information on species that are in danger of becoming extinct so that public awareness of the plight of these magnificent birds may be increased. The main text will comprise species accounts with accompanying illustrations. Vivid color plates will draw attention to the spectacular species that we have lost or that could be lost. There will be a comprehensive Introduction focusing on the three major regions of distribution, namely the Australasian distribution, the Afro-Asian distribution and the Neotropical distribution. The status of parrots in each of these distributions will be discussed, with particular attention given to threats that caused the extinction of species or are endangering extant species, as well as conservation measures being implemented or that should be implemented. Additionally, there will be an appendix with brief accounts of eight species with endangered subspecies. This will have a full-page color plate depicting these subspecies in field guide style illustrations"--.
