Description
This small, bark-gleaning bird is characterized by its distinctive white throat and stiff, rufous tail feathers, which it uses for support while climbing. It actively forages on tree trunks and branches, searching for invertebrates. Its behavior is similar to that of a nuthatch or woodpecker, moving upwards on tree bark.
