The Yardies formed in August 2011 when six Toyota and a wild rover joined five Godzilla subordinate females. However, the group never reached stability. First, the two oldest males disappeared – probably due to TB. The remaining males roved frequently, and at the end of 2011 also the Godzilla females dispersed. Two wild females joined the remainder, but they eventually got lost. The three remaining males finally immigrated into Godzilla.
