The barbet subspecies P. c. orientalis is distributed in eastern Thailand, Cambodia, Laos and Vietnam. The subspecies P. c. stuarti is distributed in peninsular Thailand.

Ecosystem and habitat

These blue-eared barbet species have moderate forest dependence. They normally occur in altitudes from 0 to 1600 meters. The artificial ecosystems and habitats of these species include, plantations, orchards and rural gardens.

The natural ecosystems and habitats of these species include, tropical and subtropical moist lowland forests, tropical and subtropical moist montane forests, broadleaf evergreen forests, mangroves and tropical and subtropical moist shrublands.

Diet and feeding behavior

The diet of this blue-eared barbet consists mainly of fruits. Wild fruits, orchard fruits, berries, figs, drupes and insects are their primary food. These barbets are mostly arboreal and forage in mid-storey and canopy.

Reproduction and breeding habits

The breeding season of these blue-eared barbet species is from January to August in most of their range. In Vietnam, laying is observed in January. In Thailand the breeding season is from March to September.

The nesting sites of these species are hollows in tree trunks, excavated by the breeding pair. These species are monogamous and territorial. The clutch usually contains two white eggs. The nestlings are fed by the parents.

Migration and movement patterns

These blue-eared barbet species are non-migrant resident birds. The populations living in the higher altitudes descent to lower levels during winter.

Post breeding, the juveniles may disperse and establish in new locations within the range. Within their range, they may make local movements for feeding and breeding.
