National Geographic Field Guide to Birds provides affordable, portable, reliable region-specific information, perfect for the novice or experienced birder. In each guide, an introduction by an expert birder from the region offers guidance on where to look for key birds. An opening section gives pointers on how to look for key birds and what to focus on when you spot them. Each guide features approximately 150 birds, grouped by family. Two indexes: one alphabetical and one color-coded help readers identify a bird quickly.
