Taxonomy: Passeriformes, Turdidae.

Favored Habitat: Meadow openings in forested habitats; edges of fields.

Where to Find: Don't look for Eastern Bluebirds around Las Vegas. Rather, look for them on trips to eastern North America.

Comments: Bluebirds tend to fly in flocks, so if you see one, look for others. Learn the call, it sounds like a single "twang" on a guitar and is distinctive.

Male Western Bluebirds have a fully blue throat and chestnut shoulders.
