Sparrows are often considered familiar to the point of invisibility, but the recent steep decline in numbers of both native British species is a reminder that these unassuming chatterboxes deserve a little more attention. Of all the true sparrow species found worldwide, only two occur in the British Isles. Globally, the story of the House Sparrow is one of dramatic expansion: from humble origins in the Middle East where they spread, along with agriculture, to become the most widely distributed bird on the planet. The smaller, more active Tree Sparrow has also spread extensively, following the domestication of rice rather than wheat, and both species have been heavily persecuted in recent years. In Spotlight Sparrows, Amy-Jane Beer examines the causes behind the decline of these familiar species, and explores their biology and life cycle, social behaviour, and the significant role that sparrows play in human culture, from Shakespeare and Edith Piaf to Captain Jack Sparrow.

With their wild glare, swift turn of foot and secretive nature, hares are the rabbit's mysterious and untameable cousin. Always a thrilling wildlife spot, the hare has long been a symbol of Britain's sweeping, open countryside. Hares have also been associated with human culture and folklore for many centuries - their associations with spring can be traced back to the druids. Focussing on our two British species, the Brown Hare (found throughout the UK and widely distributed in Europe and Asia) and its more northerly relative the Mountain Hare (found in Scotland, Ireland, Scandinavia and the Russian Federation), RSPB Spotlight Hares offers exciting and up-to-date information on these incredible lagomorphs, with chapters covering their biology, evolution, natural history, behaviour, including courtship rituals, and ecology. Information on some of the more charismatic species of hare found elsewhere in the world and on hares' other relatives, the rabbits and pikas, is also provided.

Brightly coloured and pleasingly patterned, ladybirds are among some of our most beloved and familiar invertebrates. Their role in helping to protect our crops by devouring huge numbers of pests has firmly established these tiny, flying beetles as the gardeners' friend. Spotlight Ladybirds focuses on the 26 species that are resident in the UK, from the widespread but unusual Orange Ladybird to the rare – and aptly named – Scarce 7-spot Ladybird. Ladybird expert, Richard Comont considers the conservation challenges facing these iconic species, whose populations are now at risk thanks to the threat posed by one of their own, the invasive alien Harlequin Ladybird. And he covers all aspects of ladybirds' biology, from tiny larvae emerging from their oval eggs to large aggregations that converge at specific sites around the world. Richard also examines the natural history and cultural significance of this fascinating group of beetles, from Ladybird Books to Thor.

How does a tiny box jellyfish, with no brain and little control over where it goes in the water, manage to kill a full-grown man? What harm have hippos been known to inflict on humans, and why? What makes our closest cousin, the chimpanzee, the most dangerous of all apes to encounter in the wild? In this elegantly illustrated, often darkly funny compendium of animal predation, Gordon Grice, hailed by Michael Pollan as “a fresh, strange, and wonderful new voice in American nature writing,” presents findings that are by turns surprising, humorous, and horrifying. Personally obsessed by both the menace and beauty of animals since he was six years old and a deadly cougar wandered onto his family’s farm, Grice now reaps a lifetime of study in this unique survey—at once a reading book and a resource.

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.

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.

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.
