Taxonomy and systematics

[edit]

The red-headed barbet has six subspecies:[2]

Description

[edit]

Male red-headed barbet subspecies exceptE. b. occidentalis range in weight from 30 to 41 g (1.1 to 1.4 oz). Females exceptoccidentalis weigh 31 to 38 g (1.1 to 1.3 oz). Maleoccidentalis 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.[3]

Distribution and habitat

[edit]

The subspecies of the red-headed barbet are found thus:[3]

  • E. b. salvini, Costa Rica and western Panama
  • E. b. anomalus, eastern Panama and probably adjacent northwestern 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 mountainprimary forest and also adjacentsecondary forest. The species' overall elevational range is 400 to 2,400 m (1,300 to 7,900 ft) but there are large geographic variations.[3]

Behavior

[edit]

Feeding

[edit]

The red-headed barbet's diet has not been studied in detail, but it is known to includearthropods such as caterpillars and adult insects and fruit such as berries and (at feeders) bananas.[3]

Breeding

[edit]

Little has been published about the red-headed barbet's breedingphenology. 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.[3]

Vocalization

[edit]

The red-headed barbet's song has been described as "a resonant, ventriloquial, somewhat toad-like trillkrrrrrrrrrrr"[1]. Some calls have been described as "grunts and snarls"[2].[3]

Status

[edit]

TheIUCN has assessed the red-headed barbet as being of Least Concern.[1] "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."[3]
