The Woodpecker Finch, Camarhynchus pallidus, is a species of bird in the Darwin's finch group of the tanager family Thraupidae. Woodpecker Finches occur widely in the Galapagos Islands, from sea level to high elevations. It has gained fame due to its capability of using a twig, stick, or cactus spine as a tool. The tool is used as compensation for its short tongue. The finch manipulates the tool to dislodge invertebrate prey such as grubs from trees. The same tool can be used many times on many different trees. Scientists have observed that the finches may shorten the stick or spine to make it more manageable.
