Ecosystem and habitat

These grey-capped woodpecker species have moderate forest dependence. They normally occur in altitudes from 0 to 2800 meters. The artificial ecosystems and habitats of these species include, rural gardens and plantations.

The natural ecosystems and habitats of these grey-capped woodpecker species include, tropical and subtropical moist montane forests, tropical and subtropical moist lowland forests, evergreen forests, dry shrublands and moist deciduous forests.

Diet and feeding behavior

The diet of these grey-capped woodpeckers consists mainly of insects. Caterpillars, cicadas, grasshoppers, bugs, leafhoppers, small beetles, insect larvae and pupae, flies, ants, termites are their primary food. Occasionally they feed on fruits, seeds and plant matter.

These grey-capped pygmy woodpecker species excavate holes and probe into crevices in the wood and bark for their prey. They also glean prey from leaves and twigs. They also feed from ant nests and termite mounds.

Reproduction and breeding habits

The breeding season of the grey-capped woodpecker species is from April to July in Indian subcontinent. In southeast Asia the breeding season is from December to April. The nests are excavated in trees. These birds are monogamous and territorial.

Both the parent grey-capped woodpeckers take part in excavating the nest and incubating the eggs. The clutch may contain 2-4 round, white eggs. The chicks hatch out in about 14 days and take about 25–30 days to fledge. The hatchlings are altricial.

Migration and movement patterns

These grey-capped woodpecker species are non-migratory resident birds. The birds in higher altitudes may move to lower levels during winter.

Post breeding, the juvenile woodpeckers may disperse and establish in new locations within the range. They may make local movements for feeding and breeding within their range.
