If you travel across the continent from west to east, you will encounter different types of birds at different locations along your way. For example, you might see Western Scrub-Jays in California, Gray Jays in the Canadian Rockies, and Blue Jays in Virginia. Therefore, to interpret FeederWatch data in a meaningful way, the continent is divided into fifteen FeederWatch Regions. Each region includes a group of states and provinces that share similar geological and habitat features.
