Ecosystem and habitat
These blue-throated barbet species have moderate forest dependence. They normally occur in altitudes from 200 to 2000 meters. The artificial ecosystems and habitats of these species include plantations, rural gardens, urban parks and orchards.The natural ecosystems and habitats of these barbet species include, subtropical and tropical lowland forests, subtropical and tropical montane forests, primary and secondary evergreen forests and deciduous forests.
Diet and feeding behavior
The diet of the blue-throated barbet consists mainly of fruits. Wild fruits, orchard fruits, berries, figs, flower and buds are their primary food. Sometime they feed on insects including ants, cicadas, dragonflies, crickets, locusts, beetles and mantids.Reproduction and breeding habits
The breeding season of these blue-throated barbet species is from March to July in India. Sometimes two broods are raised in a season. These birds are monogamous and territorial. Courtship includes singing and counter-singing and bobbing of head.These blue-throated barbet species mostly excavate holes in trees for nesting. The clutch contains two to four white eggs without any markings. Both pairs take turns to incubate the eggs. The chicks hatch out after 13-15 days.
Migration and movement patterns
