Origin, geographical range and distribution
These golden oriole species are distributed in Turkmenistan, Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, Afghanistan, Pakistan and Indian subcontinent.They are distributed in all the Indian states, except, Mizoram, Tripura, Manipur, Nagaland, Arunachal Pradesh, Meghalaya and Assam.
Ecosystem and habitat
These golden oriole species have high forest dependence. They normally occur in altitudes from 0 to 2400 meters. The artificial ecosystems and habitats of these species include rural gardens, plantations, orchards, agricultural lands and urban areas.The natural ecosystems and habitats of these oriole species include tropical and subtropical montane forests, foothill forests, temperate forests, deciduous and semi-evergreen forests, thorny forests, mangroves, open country with scattered trees.
Diet and feeding behavior
The diet of these golden oriole species consists mainly of fruits. Wild fruits, orchard fruits, berries of Lantana sp., plums, cherries, peaches, nectarines, apricots, almonds and mulberries are their primary food.These oriole species are also known to feed on insects, small lizards, small mammals, eggs and hatchlings.
Reproduction and breeding habits
The breeding season of these Indian golden oriole species is from April to September in India. The laying season is during May and June in Nepal. The breeding season is during June in Afghanistan.These Indian golden oriole species are monogamous and territorial. The nesting sites are located high in outer edge of well-foliaged tree canopy. The nest is suspended on a thin horizontal forked branch like a hammock. Both the parents take part in nest building.
The golden oriole nest is a open cup-like structure, woven with grass, twigs, sedges, cloth, reeds, strings, leaves, paper and plant fibers. It is lined with feathers, rootlets, straw, fur, wool, moss and lichens.
The clutch contains three to five white eggs with pink, brown and black speckles. The eggs are incubated by both the parents. The hatchlings are cared for by both the parents.
Migration and movement patterns
These golden oriole species are partially migratory birds. The migratory breeding populations are distributed in Turkmenistan, Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan, Afghanistan, Pakistan and the Himalayan region of the Indian subcontinent.These migratory golden oriole breeding populations move southwards from September onwards to Indian peninsula for wintering. There are resident breeding populations in the central parts of the Indian subcontinent.
Post breeding, the resident juveniles may disperse and establish in new locations within the range. Within their range they may make local movements for feeding and breeding.
