Название: RSPB Spotlight Ducks and Geese Автор: Marianne Taylor Издательство: Bloomsbury Wildlife Год: 2020 Формат: EPUB Размер: 85 Мб Язык: английский / English
This will be a detailed 'biography' of ducks and geese that breed in or regularly visit the UK – covering 30 species in all. It will include chapters on the evolution of ducks and geese, their place in the natural world, their anatomy and physiology, various feeding methods, spectacular courtship displays and diverse breeding behaviour. Marianne Taylor will reveal their often epic migrations and examine their social interactions with their own and other species, including their unusual readiness to hybridise. She will also detail their relationships with humankind over the centuries, including their presence in folklore and literature and their role in our lives as both prey and pets. She will also explore their presence as feral and sometimes invasive species outside their natural ranges, and their current status within their native wild ranges as the group includes several species recently recognised as being of global conservation concern. |

Название: RSPB Spotlight Swifts and Swallows Автор: Mike Unwin Издательство: Bloomsbury Wildlife Год: 2018 Формат: EPUB Размер: 89 Мб Язык: английский / English
People all over Britain and Europe have long welcomed the arrival of swifts and swallows as a promise of summer being just around the corner. And with their similar long wings and dashing flight, it is perhaps understandable that we often confuse the two birds. After all, they have much in common: both feed on flying insects, both breed around buildings, and both are long-distance migrants that spend winter in Africa. But appearances can be deceptive. Swifts and swallows are completely unrelated birds that have adapted through evolution to survive in similar ways. In Spotlight: Swifts and Swallows, Mike Unwin reveals their fascinating lifestyles, explains how and why they have acquired their similarities, and ways in which we can help protect them. |

Название: RSPB Spotlight Eagles Автор: Mike Unwin Издательство: Bloomsbury Wildlife Год: 2016 Формат: EPUB Размер: 16 Мб Язык: английский / English
Eagles are among the most impressive hunters of the animal world. Their predatory prowess and flying skills have imbued them with a romance and mystique that runs deep in our culture and has elevated them to emblems of freedom and power across the globe. At the same time, however, people have long seen eagles as competitors. Reviled by farmers and gamekeepers as snatchers of livestock, many species have been driven into decline by persecution and disturbance. Two species of eagle occur in Britain - among 60 worldwide - and are the focus of this book. The regal Golden Eagle is the definitive 'true' eagle and occurs in wilderness areas across the northern hemisphere; the even larger White-tailed Eagle, reintroduced to the UK after historic extinction, belongs to the separate 'sea eagles' genus. |

Название: RSPB Spotlight: Foxes Автор: Mike Unwin Издательство: Bloomsbury Wildlife Год: 2015 Формат: EPUB Размер: 100 Мб Язык: английский / English
Hero or villain? Few animals divide opinion like the Red Fox. This most successful of the world's wild canids has lived alongside people from time immemorial. Celebrated by some for its resourcefulness and lush pelt, reviled by others for plundering chicken runs and overturning bins, it has worked its way deep into Western. Behind the folklore and tabloid headlines, however, lies a remarkable natural history success story. In Spotlight: Foxes Mike Unwin explores how the Red Fox's versatility has allowed it to thrive across the northern hemisphere, from desert and mountain to farmland and urban jungle. This informative ebook covers all aspects of the Red Fox biology and lifestyle, including hunting and caching food, defending a territory, raising a litter and understanding the secrets of its complex vocalisations and body language. Finally, he examines the complex, often troubled relationship that the Fox has enjoyed and both endured with humankind, and suggests what the future might hold. |

Название: RSPB Spotlight Snakes Автор: Jules Howard Издательство: Bloomsbury Wildlife Год: 2020 Формат: EPUB Размер: 127 Мб Язык: английский / English
Snakes are superbly secretive reptiles, celebrated by many for their highly tuned senses and their complex and mysterious seasonal behaviours. Though some people may be fearful of them, these important reptiles play a crucial role in many habitats. And an encounter with any one of our native snake species is an experience worth cherishing. In Spotlight Snakes, Jules Howard takes readers on a journey through the ecology and lifestyle of Britain's three native snake species: the Barred Grass Snake, the Smooth Snake and our only venomous snake species, the Adder. As well as uncovering their unique hunting styles and courtship rituals, he delves into the myths and legends at the heart of humankind's widespread and sometimes troublesome fascination with these animals. He also charts the conservation challenges our native snakes face in the modern age and explores the solutions conservationists are employing to help these extraordinary predators remain a vital part of British ecosystems for generations to come. |
