The giant root-rat of the Bale Mountains, Ethiopia has been reported to have a mutualistic relationship with a passerine, which involves eavesdropping on its alarm call. We tested this in a field playback experiment. Besides the alarm call, we included two sounds potentially acting as alarm cues and one as a control. Little reaction of root-rats was detected to the bird alarm call. However, intensive reaction was detected to an alarm call of the black-clawed brush-furred rat, a social rodent often occupying root-rats’ burrows. This result is understandable given the two rodents have the same principal predator, the Ethiopian wolf.
