Green-backed Firecrown Sephanoides sephaniodes

The only hummingbird in most of southernmost South America. Fairly common to common in woodlands, forests, gardens, matorral, and flowering hedges and bushes in farmland of lowlands and foothills. Rather stocky with a straight, sharply pointed bill, and a white spot behind the eye. Often looks simply dark and green overall; male’s “firecrown” rarely catches the light, but forehead often looks rather bushy or plush; female has a green crown.
