Crimson Breasted Barbet

The Coppersmith BarbetCrimson-breasted Barbet or Coppersmith (Megalaima haemacephala), is a bird with crimson forehead and throat which is best known for its metronomic call that has been likened to a coppersmith striking metal with a hammer. It is a resident found in the Indian Subcontinent and parts of Southeast Asia. Like other barbets, they chisel out a hole inside a tree to build their nest. They are mainly fruit eating but will take sometimes insects, especially winged termites.

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.

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.

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.

The call is a loud rather metallic tuk…tuk…tuk (or tunk), reminiscent of a copper sheet being beaten, giving the bird its name. Repeated monotonously for long periods, starting with a subdued tuk and building up to an even volume and tempo, the latter varying from 108 to 121 per minute and can continue with as many as 204 notes. They are silent and do not call in winter.

The beak remains shut during each call - a patch of bare skin on both sides of the throat inflates and collapses with each tuk like a rubber bulb and the head is bobbed.

They eat nearly 1.5 to nearly 3 times their body weight in berries each day. Prefers BanyanPeepul, 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. 

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.
