Samenvatting:
Anyone can get involved in gathering data for ongoing, actual scientific studies such as the Audubon Bird Count and FrogWatch USA. Just get out into a field, urban park, or your own backyard. You can put your nose to a monarch pupa or listen for raucous frog calls. You can tally woodpeckers or sweep the grass for ladybugs. This book, full of engaging photos and useful tips, will show you how.
