Where: Arizona.

What: The convergence of four distinct bioregions-the Sonoran and Chihuahuan deserts, and the Sierra Madre and the Rocky Mountains-provides a prime mix of habitats for more than 400 species of birds. Summer is the richest viewing season, with highlights including elegant trogons, painted redstarts, and more than a dozen species of hummingbirds, but the birding is superior at any time of year.

Look for: Broad-billed hummingbird
