Certhidea olivacea occurs on all of the17 major islands of the Gala¤pagos (Grant1986).The six populations analysed here were divided into two groups, C. olivacea and Certhidea fusca, because the mean GST between these groups (2.06) was larger than any other distance among Darwin’s ¢nch species.Themean GST distancesamong C. olivacea Description identification.
