Taxonomy and systematicsEdit
The red-headed barbet has six subspecies:
Male red-headed barbet subspecies except E. b. occidentalis range in weight from 30 to 41 g (1.1 to 1.4 oz). Females except occidentalis weigh 31 to 38 g (1.1 to 1.3 oz). Male occidentalis weigh 37.8 to 45.1 g (1.33 to 1.59 oz) and females 37.8 to 43.7 g (1.33 to 1.54 oz). Males have a red head, an orange to yellow breast, and a white belly . A white collar separates the head from the olive green back. The amount of red on the throat and chest and the width of the orange-yellow breast band vary among the subspecies. The female's crown and nape vary from dull orange to shades of green among the subspecies. Several have a black forehead. Its back is green, the throat grayish yellow with a yellow to orange band below it. Its lower breast is olive-yellow and the belly white. As in the male, there is some variation among subspecies.
Distribution and habitatEdit
The subspecies of the red-headed barbet are found thus:
- E. b. salvini, Costa Rica and western Panama
- E. b. anomalus, eastern Panama and probably adjacent nortwestern Colombia
- E. b. occidentalis, both slopes of Colombia's Western Andes
- E. b. bourcierii, Andes of western Venezuela, the east slope of Colombia's Central Andes, and both slopes of Colombia's Eastern Andes
- E. b. aequatorialis, coastal mountains and the western slope of the Andes in Ecuador
- E. b. orientalis, eastern slope of the Andes in Ecuador and northern Peru
The red-headed barbet inhabits the interior and borders of evergreen mountain primary forest and also adjacent secondary forest. The species' overall elevational range is 400 to 2,400 m (1,300 to 7,900 ft) but there are large geographic variations.
Little has been published about the red-headed barbet's breeding phenology. Like other New World barbets, they excavate cavities in trees and sometimes in fence posts. The clutch size is two to five; the female incubates at night and both sexes do so during the day.
The IUCN has assessed the red-headed barbet as being of Least Concern. "Although the overall population trend is believed to be one of decline, the rate of decline is not thought to be a cause for concern."
