Thanks to their speed, size and nocturnal habitats, bats are among the most interesting, and least understood, mammals that frequent our homes and gardens. From their ability to make sounds that are above the range of human hearing, to their reliance on echolocation to navigate objects and find prey, their unique behaviour means that bats are seldom seen or heard. With nearly 1,400 species worldwide, bats make up around 25 per cent of all mammal species. Spotlight Bats features all 17 species that live and breed in the British Isles, as well as an array of the most fascinating bats from around the world, including some of the more charismatic species such as vampire bats and fishing bats. Nancy Jennings uses up-to-date research to provide insights intothe lives of these elusive mammals, covering the biology, diversity, evolution and ecology of bats, as well as their interactions with humans and folklore.

Woodpeckers are fascinating birds, filling our forests with their unmistakable drumming, and capturing our imaginations with their incredible ability to drill holes in trees and their bright, colourful plumage. Three species of woodpecker are resident in the UK: the Green Woodpecker, often seen on lawns and in fields; the Great Spotted Woodpecker, a frequent visitor at garden bird-feeders; and the tiny Lesser Spotted Woodpecker, sadly now in decline. The Wryneck – which twists its neck 'like a snake' when threatened – also passes through the UK on its yearly migration and has captivated people throughout the ages. Gerard Gorman provides a close-up look at the lives of these birds, from their anatomy, diet and nesting habits to their iconic drumming behaviour. He also explores the relationship that humans have enjoyed with woodpeckers for centuries, in folklore, myth and conservation, and gives tips on how to observe these wonderful birds in the wild.

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.
