Paul Sterry is a biologist, author and photographer whose interest in natural history spans more than 50 years. He has travelled widely, pursuing his interest in the natural world, gathering photographic material for his books, and taking stock images for his photo library, Nature Photographers Ltd (http://www.naturephotographers.co.uk). Recently, Paul's interests have centred on British wildlife and its conservation. He has written more than 50 books on British wildlife, including numerous field guides. Almost all the titles are largely illustrated by images from the archive of Nature Photographers Ltd. Among Paul's most proud achievements are books in the critically acclaimed 'Collins Complete' series of field guides; recent titles on Coastal Wildlife, and Mushrooms and Toadstools, have set new standards in terms of image quality and the role that photography has to play in the identification of plants and animals.
