Identificación

About 28 centimetres (11 in) in length. Mostly crimson with black trailing edges to wings. underparts white with messy black marks. The breast and neck are black with white spots on the throat and white streaks on the breast. A black eyestripe stretches to the back of the neck and diffuses into the nape and upper back, with white streaks between the eye and neck. It has a red crown, with the forecrown and forehead black speckled with white in females. The eye is hidden among the black eyestripe. It has a fairly sized grey bill, which forms a blunt point. Juveniles are duller with less bold markings, with males having white spots on crown and females with few spots if not none. Hybrids can be either mostly red with orange or yellow (closer to Red-backed flameback) or mostly yellow with red or orange (closer to Black-rumped flameback)

Comportamiento

Its voice is a sharp whinny which is more unmusical and screeching than that of D. benghalense. It can either go along in a rhythmic "woik-woik-wik-wi-ti-ti-t-t t-t-trrrrrr!" or a repeated "woik-tri-tri-tri-tri-tri-tri-tri- !" which lasts for three seconds. Has a dull drumroll of 0.8 - 1.5 seconds.<p>Its main source of food are ants. It seems to prefer Carpenter ants (Camponotus spp.), ants in the genus Meranoplus, and the pupae and larvae of Asian weaver ants (Oecophylla smaragdina). Other invertebrates eaten include spiders, caterpillars, weevils and beetles. Also feeds on some fruit occasionally, as a source of dietary fiber and other nutrients.<p>It uses its tail as a support to climb trees, and flies in a flap-and-glide bounding pattern. It breaks into leaf nests of weaver ants in the trees themselves but descends to the ground to access nests of ground ants. Forages alone, in pairs or as a family group, and often joins multi-species foraging flocks, like other Dinopium flamebacks. <p>It drills nest holes at many variable heights. These holes, which can only be built by woodpeckers, barbets and other Piciformes, are nesting sites for other cavity-nesting birds like parrots, who cannot make their own holes. Sometimes broods twice, but usually only one clutch is laid per season. It breeds from December-September, predominantly from August-September and from February-June. Two-three eggs are laid per clutch.

Conservación

It is marked as least concern on the IUCN red list, because it has a stable yet unknown population and is common to locally common in its comparatively small range. No declines nor threats have been identified. It is very common, one of the "Common" endemics throughout Sri Lanka, along with the Sri Lankan junglefowl, the Sri Lanka hanging parrot, and the Crimson-fronted barbet. It is the most common woodpecker species in Sri Lanka.
