内容简介
Waterfowl are a varied and fascinating group of birds. This very portable guide is designed to help you identify these birds in their natural habitats and learn about their habits, life cycles, and history. The guide features 74 species of North American birds associated with fresh or salt water. In addition to the swans, geese, and duck that are traditionally termed waterfowl, it includes a variety of loons, grebes, cormorants, and rails that may be encountered in the same habitats. Also here are tips on birding technique (including the use of binoculars and spotting scopes), identification skills, and watching waterfowl, as well as notes on waterfowl conservation and more.
