Piculet

The piculets are a distinctive subfamily of small woodpeckers which occur mainly in tropical South America, with just three Asian and one African species.

Like the true woodpeckers, piculets have large heads, long tongues which they use to extract their insect prey and zygodactyl feet, with two toes pointing forward, and two backwards. However, but they lack the stiff tail feathers that the true woodpeckers use when climbing trees, so they are more likely than their relatives to perch on a branch rather than an upright trunk.
