The Charming hummingbird (Amazilia decora or Polyerata decora), also known as Beryl-crowned Hummingbird - occurs naturally in Central America- specifically Costa Rica and Panama. It has a violet-blue chest and a greenish throat. It is sometimes considered conspecific with the Blue-chested Hummingbird found on the Caribbean slope as they are nearly identical. The sparkling green on the head is more extensive which helps distinguish it from the Blue-chested. Charming Hummingbirds inhabit open woodlands, coffee plantations, second growth, and gardens with flowering trees. It is regionally endemic to the Southern Pacific lowlands and coastal areas of Costa Rica north to Carara and Panama. Males and females that defend territories at flowers such as the Charming Hummingbird are those hummingbird species that are brightly coloured to show off their iridescent costumes in contrast to the flowers. Hermits do not hold territories in the same way and are not generally very colorful in comparison.
