Life History and Behavior

Behavior

Behaviour

"The Golden-backed Woodpecker affects open scruband-tree jungle and is also partial to mango topes, groves of ancient trees and cocoanut plantations. It is not shy and freely enters gardens and compounds in the proximity of human habitations. The birds go about in pairs, following each other from tree to tree. They cling to the trunks low down and work upwards systematically, direct or in spirals, in short jerky spurts, tapping on the bark at intervals to dislodge insects and to discover the hidden galleries and grubs of boring beetles. Occasionally a bird will slide a few feet down—in ' reverse gear '—to investigate some promising crevice. The dipping flight, typical of the woodpeckers, is noisy and consists of several rapid wing strokes followed by a pause. The call, uttered principally on the wing but also while at rest, is a loud, harsh, chattering ' laugh.' Black ants form a considerable proportion of its food. They are captured on the trees, as well as on the ground. We have observed one clinging to a half-ripe mango, digging into it and swallowing the pulp. Occasionally it also feeds on the nectar of Coral flowers."

Reproduction

"The season is between March and August, and two successive broods are commonly raised. The eggs are laid in a hollow in a stem or branch excavated by the birds, 8 to 30 feet from the ground. The round entrance hole is about 3 inches across. The shaft or tunnel ends in a widened egg chamber. The normal clutch consists of three eggs, glossy china white, unmarked. Both sexes share in excavating the hollow, incubation and tending the young."

Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Black-rumped flameback

The black-rumped flameback (Dinopium benghalense), also known as the lesser golden-backed woodpecker or lesser goldenback, is a woodpecker found widely distributed in the Indian subcontinent. It is one of the few woodpeckers that are seen in urban areas. It has a characteristic rattling-whinnying call and an undulating flight. It is the only golden-backed woodpecker with a black throat and black rump.[2]

Description[edit]

Nominate race Kolkata, India.

The black-rumped flameback is a large species at 26–29 cm in length. It has a typical woodpecker shape, and the golden yellow wing coverts are distinctive. The rump is black and not red as in the greater flameback. The underparts are white with dark chevron markings. The black throat finely marked with white immediately separates it from other golden backed woodpeckers in the Indian region. The head is whitish with a black nape and throat, and there is a greyish eye patch. Unlike the greater flameback it has no dark moustachial stripes.[2][3]

The adult male has a red crown and crest. Females have a black forecrown spotted with white, with red only on the rear crest. Young birds are like the female, but duller.[2]

Like other woodpeckers, this species has a straight pointed bill, a stiff tail to provide support against tree trunks, and zygodactyl feet, with two toes pointing forward, and two backward. The long tongue can be darted forward to capture insects.[4]

Leucistic birds have been recorded.[5] Two specimens of male birds from the northern Western Ghats have been noted to have red-tipped feathers on the malar region almost forming a malar stripe. A female specimen from Lucknow has been noted to have grown an abnormal downcurved hoopoe-like bill.[6]

Subspecies[edit]

Sri Lankan variation

The race in the arid northwestern India and Pakistan, dilutum, has pale yellow upperparts, a long crest and whiter underparts than the nominate race of the Gangetic plains. The upperparts have less spots. They prefer to breed in old gnarled tamarisks, Acacia and Dalbergia trunks. The nominate populations is found across India in the low elevations up to about 1000 m. Southern Peninsular form puncticolle has the throat black with small triangular white spots and the upper parts are a bright golden-yellow. The subspecies found in the Western Ghats is sometimes separated as tehminae (named after the wife of Salim Ali) and is more olive above, has fine spots on the black throat and the wing-covert spots are not distinct. The southern Sri Lankan subspecies D. b. psarodes has a crimson back and all the dark markings are blacker and more extensive. It hybridizes with the northern Sri Lankan race jaffnense which has a shorter beak.[2] The Sri Lankan race psarodes is sometimes considered a distinct species although it is said to intergrade with jaffnense near Puttalam, Kekirawa and Trincomalee.[7]

Distribution and habitat[edit]

This flameback is found mainly on the plains going up to an elevation of about 1200m in Pakistan, India south of the Himalayas and east till the western Assam valley and Meghalaya, Bangladesh and Sri Lanka. It is associated with open forest and cultivation. They are often seen in urban areas with wooded avenues.[4] It is somewhat rare in the Kutch and desert region of Rajasthan.[8]

Behaviour and ecology[edit]

A female

This species is normally seen in pairs or small parties and sometimes joins mixed-species foraging flocks.[9] They forage from the ground to the canopy. They feed on insects mainly beetle larvae from under the bark, visit termite mounds and sometimes feed on nectar.[10][11] As they make hopping movements around branches, they often conceal themselves from potential predators.[12] They adapt well in human-modified habitats making use of artificial constructions[13] fallen fruits[14] and even food scraps.[15]

The breeding season varies with weather and is between February and July. They frequently drum during the breeding season.[16] The nest hole is usually excavated by the birds and has a horizontal entrance and descends into a cavity. Sometimes birds may usurp the nest holes of other birds.[17] Nests have also been noted in mud embankments.[18] The eggs are laid inside the unlined cavity. The normal clutch is three and the eggs are elongate and glossy white.[4][19] The eggs hatch after about 11 days of incubation. The chicks leave the nest after about 20 days.[20]

In culture[edit]

The Sri Lankan these woodpeckers go by the generic name of kæralaa in Sinhala. In some parts of the island, it is also called kottoruwa although it more often refers to barbets.[21] This bird appears in a 4.50 rupee Sri Lankan postal stamp.[22] It also appears in a 3.75 Taka postal stamp from Bangladesh.
