Coppery-Headed Emerald - Elvira cupreiceps 

 

Description

 

  • The Coppery-Headed Emerald retains a distinct and dazzling appearance.  This species of hummingbird has a decurved bill, white outer tail feathers that turn black near the tip.  The crown, upper tail, and central tail feathers of the male are copper, while the females are more lightly colored, with a white underside, and light green spots around their backs. 

    • Their decurved bill seperates them from hummingbirds simular to the Coppery-Headed Emerald.

 

  • They average around three inches, and weigh only three grams.

Habitat & Diet

 

  • The Coppery-Headed Emeralds roam at the middle elevation of the Caribbean Slope, south to the Reventazon River, and they are also commonly spotted on the Pacific slope of Cordillera de Guanacaste and Tilarán.  They are commonly spotted near Monteverde as well.

 

  • Like most other hummingbirds, the Coppery-Headed Emerald recieves most of their nutrition from nectar and small insects. 

    • Since their bill is short, they tend to forage in small flowers .
