This pocket guide is a useful tool and fun reminder of how to look at the world around you with care and close observation every day. Use this guide to identify whether you've found a bee or wasp, centipede or millipede, moth or butterfly. Compare shapes of seeds, leaves, and feathers to deduce their origin. Notice snail trails, and make discoveries by turning over a leaf. Learn how to observe—listen, look, record, and collect. With its how-to guides, comic illustrations, weatherproof cover, and built-in, useful tools—such as a ruler, key, and quick access sections—this handy guide will enliven every expedition. After poring over Giselle Clarkson's rich, oversized books indoors, every observologist and omnibirder can slip this guide in their pocket and set out on small scientific outings every day.
