Coppery-headed Emerald Hummingbird
The coppery-headed emerald (Microchera cupreiceps ) is a small hummingbird endemic to Costa Rica. It measures a mere 3 inches (7.6 cm) in length, and weighs only 3 grams (0.11 oz). The male has distinctive coppery crown and rump with a whole green belly and white vent. The female has a white belly and a narrow black subterminal band on white outer rectrices of the tail. Found in forests and edges, usually singly but males sometimes gather to display.
