The perfect guide to the birds of Melanesia - New Caledonia, the Solomons, the Bismarcks and Vanuatu. Written by leading ornithologist, Guy Dutson, this new Helm Field Guide covers the species-rich Melanesia region of the south-west Pacific, from New Caledonia and the Solomons through the Bismarcks to Vanuatu. This is an increasingly popular destination for tours and travellers, and one that has never before had complete field-guide coverage. For anyone travelling to this far-flung Pacific region, this book is an indispensable birdwatching guide. Species accounts include 650 superb illustrations allied with concise written information to aid quick and accurate identification. The cover star is the Kagu, the region's most iconic bird species and a highly sought-after endemic of New Caledonia.

Speciation is the process by which co-existing daughter species evolve from one ancestral species - e.g., humans, chimpanzees, and gorillas arising from a common ancestor around 5,000,000 years ago. However, many questions about speciation remain controversial. The Birds of Northern Melanesia provides by far the most comprehensive study yet available of a rich fauna, composed of the 195 breeding land and fresh-water bird species of the Bismarck and Solomon Archipelagoes east of New Guinea. This avifauna offers decisive advantages for understanding speciation, and includes famous examples of geographic variation discussed in textbooks of evolutionary biology. The book results from 30 years of collaboration between the evolutionary biologist Ernst Mayr and the ecologist Jared Diamond. It shows how Northern Melanesian bird distributions provide snapshots of all stages in speciation, from the earliest (widely distributed species without geographic variation) to the last (closelyrelated, reproductively isolated species occurring sympatrically and segregating ecologically). The presentation emphasizes the wide diversity of speciation outcomes, steering a middle course between one-model-fits-all simplification and ungeneralizable species accounts. Questions illuminated include why some species are much more prone to speciate than others, why some water barriers are much more effective at promoting speciation than others, and whether hypothesized taxon cycles, faunal dominance, and legacies of Pleistocene land bridges are real. These years of study have resulted in a huge database, complete with distributions of all 195 species on 76 islands, together with their taxonomy, colonization routes, ecological attributes, abundance, and overwater dispersal. Color plates depict 88 species and allospecies, many of which have never been seen before. For students of speciation, Northern Melanesian birds now constitute a model system against which other biotas can be compared. For population biologists interested in other problems besides speciation, this rich database can now be mined for insights.
Birds of Southwest Pacific

Download and read online ebook Birds of Southwest Pacific write by Ernst Mayr. This book was released on 2012-09-11. Birds of Southwest Pacific available in PDF, EPUB and Kindle. Perfect for birdwatching enthusiasts travelling to Indonesia, this concise guide is full of interesting information. This practical handbook, by an acknowledged authority, intended primarily for the field student, tells him how to identify and name the birds of Indonesia which he encounters, and what kinds of birds he can expect to find on each island. There is also a condensed summary of the present knowledge of distribution, geographical variation and habits. Whenever feasible, keys have been supplied to facilitate identification. These keys are simply and clearly worked out for the beginner who may not know the difference between a curlew and a godwit, or a triller and a graybird. Three magnificent color plates show 39 species which include at least one representation of all of the prominent bird families of the southwest Pacific. A series of black and white drawings show additional species. These pictures will be particularly valuable to bird students who have never seen a wood swallow, a flower pecker, a white-eye or a triller.

Download and read online ebook Australasian Eagles and Eagle-like Birds write by Stephen Debus. This book was released on 2017-08. Australasian Eagles and Eagle-like Birds available in PDF, EPUB and Kindle. 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.
