Book excerpt: A newly updated and expanded edition of the bestselling Up North books, this is an entertaining guide to Ontario's north for every cottager, camper, and nature lover. Have you ever wondered how porcupines procreate? Or where you can best see the northern lights? Or how many fireflies it takes to equal the light of a 40-watt bulb? The answers to these questions — and many, many more — are in this lively and indispensable field guide to the plants and animals of Ontario's wilderness. Filled with amusing trivia, easy-to-understand natural history, and little-known folklore, The Complete Up North is the perfect introduction and companion to Ontario's great outdoors. Naturalists Doug Bennet and Tim Tiner answer those questions we have always wanted to ask — and many others we wish we'd thought to ask — about plants, mammals, birds, fish, insects, reptiles, clouds, the night sky, the weather, and the ground we walk on. Their infectious curiosity makes Up North as fun and interesting to read as it is useful to pack for a hike into the woods.
