North American Pelicans [PDF ebook] 

With short, stubby legs, long narrow wings, and large throat pouches, North American pelicans are unique and easily recognizable birds. Found throughout the northwest, pelicans can often be seen diving towards the water or paddling around looking for fish in large groups. Endangered over the past several decades, pelicans are beginning to thrive once more thanks to nesting refuges and protection from hunting.
