 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.

Within the Old World Megalaima barbets, they are found to be basal in phylogenetic analyses. Most of the remaining Asian species are more recent in their divergence and speciation.

About nine subspecies are well recognized.
  • nominate haemacephala (P. L. S. Müller, 1776) is found in the Islands of the Luzon and Mindoro in the Philippines
  • indica (Latham, 1790) is found in the Indian Subcontinent form northeastern Pakistan and extends into Sri Lanka and Vietnam. Several former supspecies from India are synonymized into indica.

Habitat and 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.

, 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.

Vocalization

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.

s 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.

Breeding

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.

Mortality factors

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.
