This little golden chatterbox is endemic to Costa Rica and Panama.  It is found in the southern Pacific slope from Carara down through the Osa Peninsula.  Like most birds it is reliant on the remaining intact forests and begins to disappear where forests become fragmented.  This is why large tracks of forest found on the Osa Peninsula and those of Friends of the Osa for example are so important to this species.

Also known as the Beryl-crowned Hummingbird the Charming Hummingbird (Amazilia decora) is regionally endemic to the Southern Pacific lowlands and coastal areas of Costa Rica north to Carara and Panama.  It is sometimes considered conspecific with the Blue-chested Hummingbird found on the Caribbean slope as they are nearly identical.  You will often see them in coffee plantations, gardens, forest edges and along streams and open clearings feeding on Inga, Hamelia, Satryia and Heliconia.  Like many tropical species Charming Hummingbirds form courtship assemblies or “leks” of up to 12...
