Comportamento

The rufous piculet is an active bird moving singly or in small groups through the lowest storeys of the forest, usually not above 5 m (16 ft) from the ground. It forages on trunks and dead branches, on vines, in bushes, among bamboos and in tall grasses. It gleans scrupulously, probing into holes and pulling out insects with its long tongue. It sometimes works its way up a trunk in a crosswise fashion, making little flights so as to turn to face the other way, the several members of a group often working in synchrony. The diet consists of ants, their larvae, termites, small beetles, spiders and other small invertebrates.<p>In Borneo the breeding season is in February while in Malaysia, nestlings have been found in May and June. Sometimes the nest is in a hole in a dead branch, and at other times it may be in bamboo.
