They feed on insects, larvae, seeds and fruits. Their food is mainly based on insects, especially drills wood. To find the gallery is giving short knock on wood to delimit the end of the tunnel dug by the larva. At this point, begins to give strong inclined strokes, removing large wood chips to reach the channel. Remove the larva using the long tongue, sticky and with bristles at the tip, like an arrow. Search ants (Azteca sp.), Their eggs and pupae, punching branches embaúba (Cecropia sp.). Also likes fruits such as avocado.

Lives in pairs or in family groups, with the male and the female drumming in long, low sequence. During the breeding season, he digs a hole in a tree edge of the riparian forest, returning to the opening. In this way, can come and go without being hindered by branches. The females of this species of woodpecker lay on average 2-3 eggs, and the male part of care for offspring.
habits

Inhabits the interior and the high edges of forests, secondary forests, dense forests, fields and plantations with scattered trees. Solitary or in pairs lives, tearing the bark and "hammering" trunks and branches in search of insects, both in live trees as dead. Always sleep in hollow, where it is also home to the heavy rain; some prepare cavities for sleeping. Gather up early to sleep.
Voice: prolonged sequence of strong and sound "wet ..." (territorial call, both sexes); sound "bet-wärrr", "gí-gogogo", "bé-be-be-wed" (warning). Prolonged drumming "torrrrrrrr" (both sexes). In the morning, usually mark their territories with characteristic drumming. Choose a hollow tree or branch and give their peculiar beat. Start with a high blow, separate from others and diminish the range and hit high, producing an acceleration in the end.
