You can find birds wherever there is enough water, food, and shelter for them to survive, even in extreme environments such as deserts and human cities. But in general, you will find more birds in places with plenty of water, healthy native plants, and a protected, balanced ecosystem.
Beyond your own neighborhood, look for birds in healthy habitats like forests or prairies, around bodies of water, and in places where habitat changes from one type to another (for example, the edge between a field and a forest). Look for birds at all different levels of the vegetation, from treetops to shrubs to the ground, as well as in the air and in the water.
Connecting with an Audubon Center or chapter near you is a great way to learn more about birds in your area, attend bird walks, and meet other birders.
