If you travel across the continent, 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, we divide the
continent into fifteen regions. Each region includes a group of states and provinces that
share similar geological and habitat features. |
