The Geckos were formed in December 2007 by three evicted Commandos females and three wild males. For roughly a year, the group was only followed for Life History purposes, but they were not being habituated. Habituation then resumed, due to the availability of researchers to habituate them. The group was led by female Suzie Two-Tone MacFloozie, the youngest of the founding females. Most other members of the Geckos were not yet named. In September 2009, the dominant female was predated, and soon after the group could no longer be tracked, until they were considered last seen in December 2009. The group lived in the Eastern part of the reserve.
