The coppersmith barbet (Psilopogon haemacephalus), also called crimson-breasted barbet and coppersmith, is an Asian barbet with crimson forehead and throat, known for its metronomic call that sounds similar to a coppersmith striking metal with a hammer. It is a resident bird in the Indian subcontinent and parts of Southeast Asia. It carves out holes inside a tree to build its nest. It is predominantly frugivorous, but has been observed eating insects, especially winged termites.

Description

The coppersmith barbet is green with a red head, yellow cheeks and a yellow throat. Its underparts are streaked in grey and black.

Taxonomy

Bucco haemacephalus was the scientific name proposed by Philipp Ludwig Statius Müller in 1776 for a barbet from the Philippines.

Bucco indicus was proposed by John Latham in 1790 for a streaked barbet from India with a black head and red forehead.

Bucco roseus was proposed by Charles Dumont de Sainte-Croix in 1816.

Asian barbets were placed in the genus Megalaima proposed by George Robert Gray in 1842 who suggested to use this name instead of Bucco.

Xantholaema intermedia proposed by George Ernest Shelley in 1891 were barbets from Negros and Cebu islands in the collection of the British Museum.

Megalaima haemacephala delica proposed by Carl Parrot in 1910 were four barbets from Deli and Sumatra in the Bavarian State Collection of Zoology.

Megalaima haemacephala mindanensis proposed by Austin L. Rand in 1948 was a coppersmith barbet from Mount Apo in Mindanao.

Megalaema haemacephala celestinoi proposed by Ernest Thomas Gilliard in 1949 was a coppersmith barbet from Samar island of the Philippines.

Megalaema haemacephala cebuensis and Megalaema haemacephala homochroa proposed by Victoria Dziadosz and Kenneth Parkes in 1984 were coppersmith barbets from Toledo, Cebu and Tablas Island, respectively.

Molecular phylogenetic research of barbets revealed that Megalaima species form a clade, which also includes the fire-tufted barbet, the only species placed in the genus Psilopogon at the time. Asian barbets were therefore reclassified under Psilopogon, which is the older scientific name. The coppersmith barbet is one of the oldest Asian barbets in terms of genetic divergence and speciation.

Nine coppersmith barbet subspecies are recognized as of 2014: In northern India, it occurs in the valleys of the outer Himalayas up to . It is rare in northwestern Indian states and in wet forests in Assam.

The coppersmith barbet's range overlaps with several larger barbets in most of South Asia. In the Western Ghats, its range partly overlaps with the Malabar barbet.

Behaviour and ecology

The coppersmith barbet lives solitary or in small groups; larger parties have occasionally been sighted in abundantly fruiting Ficus trees. It appears to be fond of sunning in the morning on bare top branches of tall trees, often flitting about to sit next to each other. Its flight is straight, with rapid flaps.

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. It also feeds on flower petals. It eats nearly 1.5 to nearly 3 times its own 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. Birds nest and roost in cavities.

It breeds 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 also roost inside the nest holes. Pesticide poisoning has also been noted.
