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. The finches may also try various sticks or spines at one site before finding just the appropriate one that can reach and extract the prey item.
The Woodpecker Finch is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
A Woodpecker Finch Geospiza pallida was observed using bark or a wood chip as a plectrum. A feeding behavior, described as scraping and flipping epiphytes with a plectrum in a side-to-side motion, is reported for the first time among the Geospizinae of the Galapagos Islands. More

The Woodpecker Finch, Camarhynchus pallidus, is one of the so-called Darwin's finches. First described by Charles Darwin on the Galapagos Islands, it is a unique species which uses 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. More
