Mexican Violetear

A medium-sized, predominantly green hummingbird with a distinctive iridescent violet-blue ear patch and chest stripe, Mexican violetears inhabit highland and montane forests from Mexico south through Central America at elevations of 1,000–3,000 meters. Males are aggressive, highly vocal territory defenders and perform showy flight displays. They breed at high altitudes but some populations make seasonal altitudinal migrations. Among the most common hummingbirds in Mexican highland pine-oak and cloud forest habitats.
