Coppersmith Barbet

Appearance

This species of barbet is found to overlap in range with several larger barbets in most of South Asia. In the Western Ghats, it partly overlaps with the Malabar Barbet which is of a very similar size but having a more rapid call. The red forehead, yellow eye-ring and throat patch with streaked underside and green upperparts, it is fairly distinctive. Juveniles are duller and lack the red patches. The sexes are alike. The Sri Lankan form has more black on the face, more red on the breast and darker streaks on the underside.

During the nesting season, the wear and tear on the feathers can cause the plumage of the upper back to appear bluish.

Distribution

Throughout their wide range they are found in gardens, groves and sparse woodland. Habitats with trees having dead wood suitable for excavation is said to be important. Birds nest and roost in cavities.

In the Palni Hills of southern India it is said to occur below 4000 feet. In the Himalayas it is found mainly in the valleys of the outer Himalayas up to 3000 feet. They are rare in the dry desert zones and the very wet forests.

Behavior

Keeps solitary, pairs, or small groups; larger parties occasionally on abundantly fruiting Ficus trees. Fond of sunning themselves in the morning on bare top branches of tall trees, often flitting about to sit next to each other. The flight is straight, with rapid flaps.

Habitat

They compete with other cavity nesting birds and frugivores. "Megalaima asiatica" have been noted to evict them from their nest holes, while Red-vented Bulbuls have been seen to indulge in kleptoparasitism, robbing the male of berries brought to the female at the nest.

The nest holes are also used for roosting and some birds roost alone in cavities and these often roost during part of the day. Immatures will roost with the parents but often return to roost early so as not to be prevented by the parents from entering the roost cavity.

Reproduction

Courtship involves singing, puffing of the throat, bobbing of the head, flicking of the tail, ritual feeding and allopreening.

They breed through much of the year with local variation. The breeding season is mainly February to April in India and December to September in Sri Lanka. Both sexes excavate the nest on the underside of a narrow horizontal branch. They may also roost inside the nest holes. Three or four eggs are laid and like in many hole nesting birds the incubation period is not well known but has been estimated to be about 2 weeks. Both sexes incubate. Often two broods are raised in quick succession.

Food

Prefers Banyan, Peepul, and other wild figs, various drupes and berries, and the occasional insect, caught in aerial sallies. Petals of flowers may also be included in their diet. They eat nearly 1.5 to nearly 3 times their body weight in berries each day.

Predators

Adult birds are sometimes taken by predatory species. In urban areas, there are records of collisions with structures including white walls. Pesticide poisoning has also been noted.
