As fish eaters  they are highly susceptible to poisons and serve as biological indicators for toxic materials. In this first worldwide survey of cormorants  darters  and pelicans  Paul A. Johnsgard provides a color illustration of nearly every species and a variety of anatomical drawings  and he summarizes the species status and biology  including ecology  behavior  distribution  plumage  and morphology. The first section of the book focuses on comparative biology  including all 32 species of Cormorants and shags (Phalacrocoracidae)  two species of darters (Anhingidae)  and seven species of pelicans (Pelecanidae). The accounts cover species phylogeny  taxonomy  zoogeography  comparative anatomy  behavior  reproductive biology  population and breeding dynamics  and conservation biology. Detailed line drawings of the heads of all species noting age or seasonal variations help the reader identify and distinguish between each species. The book also includes keys to each species and the origins of their scientific and vernacular names.\u003c\/p\u003e","brand":"My Store","offers":[{"title":"Default Title","offer_id":45647246131253,"sku":"ByrdShop_1560982160","price":40.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8139\/0901\/files\/9781560982166.jpg?v=1781690613","url":"https:\/\/atxbooks.com\/products\/cormorants-darters-and-pelicans-of-the-world-9781560982166","provider":"ATX Books","version":"1.0","type":"link"}
