The Galapagos Islands are blessed with an abundance of unique species. There are over 10 different species of finches which have filled the nitch filled by other birds on the mainland. One of these finches, the Woodpecker Finch has been seen to use a twig as a tool to dig its preferred food (grubs) from wood. In the 1970's, when this film was taken, scientists thought only males displayed this behavior -- and not all males did. To view other videos produced by Franklin Clay Films go to www.wxyzvideos.com.
