Ecosystem and habitat
These brown-headed barbet species have moderate forest dependence.The artificial ecosystems of these brown-headed barbet species include orchards, plantations, agricultural fields, rural gardens and urban areas.
The natural ecosystems of these brown-headed barbet species include tropical and subtropical dry forests, wooded country, tropical and subtropical moist lowland forests, deciduous woods and tropical and subtropical moist shrublands.
Diet and feeding behavior
The diet of the brown-headed barbet consists mainly of fruits. A variety of wild fruits, figs, drupes, berries, cultivated garden fruits and vegetables and plantation fruits are their primary food.The figs from the Ficus spp. is the important food item of these birds. They are known to raid coffee plantations and orchards causing considerable damage to the produce.
The brown-headed barbets are also known to glean insects such as ants, termites, cicadas, grasshoppers, dragonflies, mantids, crickets, locusts, centipedes, beetles and moths from the branches and trunks of trees.
Reproduction and breeding habits
The breeding season of the brown-headed barbet species is from February to October. These birds are monogamous. Their nesting sites are tree cavities. Both the adults excavate the nesting hole.The clutch may contain 2-4 eggs. Both the parents take turn to incubate the eggs and care the hatchlings. The chick hatch out after 13 days.
Migration and movement patterns
The brown-headed barbet species are non-migratory resident birds. Birds in higher elevations may move to lower levels and plains in winter.Post breeding, the juveniles may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.
Conservation and survival
The global population size of the brown-headed barbet (Psilopogon zeylanicus) has not been quantified. The overall population trend of these species is reported to be stable.Throughout its range this barbet species is reported to be locally common to fairly common. The generation length is 8.5 years. Its distribution size is about 3,120,000 sq.km.
Habitat degradation and fragmentation, hunting and capture of adults and juveniles for pet trade are the main threats that may endanger the survival of these species.
IUCN and CITES status
The brown-headed barbet (Psilopogon zeylanicus) does not approach the thresholds for being Vulnerable, either under the range size criterion, or under the population trend criterion or under the population size criterion.The IUCN (International Union for Conservation of Nature) has categorized and evaluated the species and has listed it as of "Least Concern". The CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) status is ‘Not Evaluated’ for brown-headed barbet (Psilopogon zeylanicus).
