Sometimes classified in the family Emberizidae, more recent studies have shown it to belong in the tanager family. It is the only member of the genus Certhidea. When Darwin collected it in 1835 during the Beagle survey expedition he mistakenly thought it was a wren, but on return to England he was informed in March 1837 by the ornithologist John Gould that the bird was in the group of finches.
