Shorebirds by Jan van de Kam,Bruno Ens,Theunis Piersma,Leo Zwarts Pdf
Shorebirds are the most visible inhabitants of coastal wetlands worldwide. Many undertake spectacularly long flights between their wintering and breeding grounds, embodying the miracle of long-distance migration in a profound way. In this illustrated behavioural ecology the migration, feeding and breeding of these birds are explained in a comprehensive but simple and visually stunning form. The core of the book is based on studies of shorebirds and other waterbirds (such as ducks, geese and gulls) that migrate along the East Atlantic Flyway. The emphasis is on those using the Dutch, German and Danish Wadden Sea; examples from the rest of the world are also included. The authors are experts in the fields of bird migration, shorebird behaviour and intertidal ecology, and have contributed much to our current understanding of these subjects. The 300 magnificent portraits of waterbirds in action were taken by Jan van de Kam, one of The Netherlands' foremost wildlife photographers.
The Shorebird Guide by Michael O'Brien,Richard Crossley,Kevin Karlson Pdf
When many birders go out looking at shorebirds, they see a distant mud flat full of grayish brown birds in various shapes and sizes and have no idea where to begin the identification process. When advanced birders look at that same flock of shorebirds, they can identify the vast majority of birds with a quick binocular scan. Experts use the simplest, most easily observed characteristics--size, structure, behavior, and general color patterns--almost subconsciously, and can identify most birds even before looking carefully at plumage details. Now birders of all levels can learn how to identify these wildly popular birds quickly and with much less effort. This guide provides more than 870 stunning color photographs, sequenced to give a general impression of a species first and progressing to a more detailed image of the bird throughout its life cycle. Captions list characteristics in order of importance, reflecting the thought process that experts use to identify birds.
Shorebirds by John Marchant,Peter Hayman,Tony Prater Pdf
This is a review of the whole family of waders. This seminal title remains the definitive book on waders – known in the US as shorebirds. Everything you might want to know about these masters of shore and wetland.
Among birds, shorebirds provide some of the more unique opportunities to examine basic problems in behavior, ecology, and evolution. This is in large measure due to the diversity, both behaviorally and ecologically, of a group closely related taxonomically and distributed throughout the world. The overall aim of these two volumes is to provide a representative selection of current research being conducted on shorebird behavior and ecology. Traditionally, marine birds have included those species that breed in large colonies on offshore islands along coasts (see Volume 4 of this series). Although shorebirds have generally not been considered within this group, the fact that almost 40% of the species breed along coasts and more than 60% often or always spend the nonbreeding season in coastal habitats more than justifies their inclusion as marine birds (at least those species that totally or partially depend upon the marine environment). Their inclusion markedly increases species diversity in marine birds since shorebirds add about 217 species to the 280 that are traditionally thought of as marine.
The Action Plan for Australian Birds 2010 by Stephen Garnett,Judit Szabo,Guy Dutson Pdf
The Action Plan for Australian Birds 2010 is the third in a series of action plans that have been produced at the start of each decade. The book analyses the International Union for Conservation of Nature (IUCN) status of all the species and subspecies of Australia's birds, including those of the offshore territories. For each bird the size and trend in their population and distribution has been analysed using the latest iteration of IUCN Red List Criteria to determine their risk of extinction. The book also provides an account of all those species and subspecies that are or are likely to be extinct. Each categorisation is justified on the basis of the latest research, including much unpublished material that has been made available during workshops conducted with leading ornithologists and conservation biologists around the country as well as phone interviews and correspondence. The result is the most authoritative account yet of the status of Australia's birds. In this completely revised edition each account covers not only the 2010 status but provides a retrospective assessment of the status in 1990 and 2000 based on current knowledge, taxonomic revisions and changes to the IUCN criteria, and then reasons why the status of some taxa has changed over the last two decades. Maps have been created specifically for the Action Plan based on vetted data drawn from the records of Birds Australia, its members and its partners in many government departments. The book contains some surprises – some alarming, some encouraging. The status of some birds has improved over the last two decades as a result of dedicated conservation management. Some may not have changed status but at least they are holding their own. Many, however, are continuing to decline and a distressing number are new to the list. There is also an increasing number of birds for which captive insurance populations need not only to be considered as a future option but actively pursued before it is too late. But this is not a book of lost causes. It is a call for action to keep the extraordinary biodiversity we have inherited and pass the legacy to our children. Every one of Australia's threatened taxa can be saved. This book describes the populations of species at greatest risk and outlines ways we can turn them around. 2012 Whitley Award Commendation for Zoological Resource.
The Action Plan for Australian Birds 2020 by Stephen T. Garnett Pdf
The Action Plan for Australian Birds 2020 is the most comprehensive review of the status of Australia's avifauna ever attempted. The latest in a series of action plans for Australian birds that have been produced every decade since 1992, it is also the largest. The accounts in this plan have been authored by more than 300 of the most knowledgeable bird experts in the country, and feature far more detail than any of the earlier plans. This volume also includes accounts of over 60 taxa that are no longer considered threatened, mainly thanks to sustained conservation action over many decades. This extensive book covers key themes that have emerged in the last decade, including the increasing impact of climate change as a threatening process, most obviously in Queensland's tropical rainforests where many birds are being pushed up the mountains. However, the effects are also indirect, as happened in the catastrophic fires of 2019/20. Many of the newly listed birds are subspecies confined to Kangaroo Island, where fire destroyed over half the population. But there are good news stories too, especially on islands where there have been spectacular successes with predator control. Such uplifting results demonstrate that when action plans are followed by action on the ground, threatened species can indeed be recovered and threats alleviated.
