Book Description
Named after a Sardinian princess of the fourteenth century who established laws protecting falcons, Eleonora's falcon is the only European bird to breed in autumn and feed its brood on the mass of birds that migrate from Europe to Africa between July and October. It breeds on small Mediterranean islands in colonies of up to 200 pairs and hunts often in groups, preying on more than 90 species of migrant birds. During the winter this falcon visits the rain-soaked woodlands of Madagascar. In this study—illustrated beautifully and extensively with 59 line drawings and 38 photographs—Hartmut Walter shows how the unique geographical and biological situation of Falco eleonorae makes the species' health an important indicator of environmental decay. For though it lives in relatively isolated areas, Eleonora's falcon nevertheless may ingest the many pollutants contained in its diet of birds migrating from industrial Europe. Walter, who has studied raptors on several continents and has been an ornithologist since his early youth, examines several discrete colonies of Eleonora's falcon. He concentrates on the species' intraspecific behavior and ecology—such as the falcons' aggressive actions, hunting strategies, and response to fluctuating environmental conditions—and investigates their evolutionary past.

Book Description
The falcon's approach to perfection of form and function has engendered a universal fascination for these superb predators. This book is both a comparative study of falcons, and a celebration of these most masterful of all avian hunters.

Book Description
Bird migration is one of the most astonishing feats in the natural world. Millions of birds migrate, often over very large distances, to benefit from seasonal resource surpluses and to avoid predators and competitors. The aim of this study is to survey the phenomena.

Book Description
This monograph is the result of eight years of bibliographical and field research concerning several behavioural ecology aspects of the Palaearctic falcons. For a while, this book grew along with “The Lanner falcon” published in 2015 and revised in 2017. In both books the main aim was to provide a clear overview of the biology and ecology of these species. In fact in the last 20 years, the number of publications on falcons has grown tremendously and, in parallel, also those belonging to the so-called "grey literature". The number of people involved is also increased by including both academics and nature lovers. Many previously published books emphasized identification, and offered little insights on the behavioural and ecological aspects of the species. Very often, the research on behavioural ecology remains closed within the confines of academic community. By contrast, a multitude of basic data is scattered in countless articles published in local magazines. Many falcon species are easy to observe and study (such as kestrels) but others are more rare and localized. In order to understand the survival strategies adopted by this group of avian predators, it is necessary not to lose sight of the overall picture. This book tries to explain the different survival strategies by examining, through a few essential chapters, some crucial aspects for all species. The first chapter provides information on the genus Falco, its genetics, evolution and morphological peculiarities. The other chapters deal with reproductive strategies, competition, exploitation of resources, dispersal patterns, communication and sociality. One of the main objectives of this book is to produce an accessible but scholarly curated source of reference. By understanding the most common species, it is possible to provide a working framework for rarer, and especially threatened, falcon species.

Book Description
This major new field guide covers Madagascar and the Indian Ocean islands, including the Seychelles, Coromos and Mascarenes (Mauritius, Réunion and Rodrigues). The Malagasy region contains one of the most extraordinary concentrations of biodiversity in the world. Its recognition as a zoogeographic region in its own right has recently been confirmed and, all taxa combined, the region was found to hold the second most distinct assemblage of vertebrates in the world after the Australian region, despite being the smallest of them all. This Helm Field Guide covers the whole of the Malagasy region, which comprises the unique island of Madagascar and the various islands and archipelagos of the Indian Ocean including the Seychelles, Comoros and Mascarenes (Mauritius, Réunion and Rodrigues). Every resident and migrant species is covered in full detail with a colour distibution map for each. Vagrants are also treated in detail, but without maps. All species are illustrated on a beautiful series of 124 colour plates, with artwork from John Gale and Brian Small. Conveniently, the plates have been arranged so that all the key species of the various archipelagos are placed together in sections. This is a major work of reference on the birds of the region and will remain the standard text for many years to come.

Book Description
Isolated for at least 120 million years, Madagascar has developed a unique flora and fauna. The fourth largest island in the world, Madagascar has 260 species of birds, no fewer than 108 of which are endemic and a further 25 of which are endemic to the Malagasy Region (Madagascar, the Comoros, Mauritius, Reunion, and their outlying islands). This book is a photographic field guide to the avifauna of Madagascar. The text for each species describes all known plumages likely to be encountered in Madagascar, vocalizations (many of which have not been previously described), habitat and behavior, range within Madagascar and worldwide, status (including taxonomic notes where relevant, subspecies, and global conservation status), and where to locate the species in Madagascar. There is also an invaluable section that summarizes distinctions from similar species. The introduction gives an overview of the birds found on Madagascar and the habitat zones where they are most likely to occur. There is also a short gazetteer to the major birdwatching locations on the island that, together with the where to watch section of the species accounts, should enable prospective visitors to plan their itineraries so that they can see nearly all the Madagascan endemics and regularly occurring species.

Book Description
This book is the ultimate flight-identification guide for the raptors of the Western Palaearctic, covering Europe, North Africa, the Middle East (including Arabia) to Central Asia. Raptors are notoriously hard to identify, even if seen well, and represent perhaps the toughest of all ID challenges for birders. This guide provides identification information for all 60 species that regularly occur in the region, to subspecific level. The text covers every plumage and age in detail, with each species account accompanied by a range of photographs covering all the principal plumages. Based on this stunning photographic coverage, most of which has never been published before, this book represents a landmark in bird identification books and a major work for all raptor enthusiasts.

Book Description
The first comprehensive field guide to the birds of Oman With its unique blend of Western Palearctic, Oriental and Afrotropical components, and lying on a migratory crossroads, Oman is a jewel of the Middle East. This is the first comprehensive field guide to the birds of this fascinating and welcoming country. All 528 species on the Oman Bird List are featured on the 116 colour plates, illustrating many of the distinct plumages and races, plus a few non-naturalised escapes. Species accounts cover key identification features - including habitat and voice - with colour maps showing the breeding, wintering and migration distributions for all regularly occurring species.
