The study suggests grey squirrels eavesdrop on the chatter of nearby songbirds to figure out when danger has passed. But the latest study suggests animals may also keep an ear out for everyday chitchat among other species as a way to gauge whether there is trouble afoot.

Scientists in the US observed the squirrels waiting patiently to come off high alert upon hearing the shriek of a predator call - and becoming more relaxed when they are.

The grey incarnation of the furry-tailed rodents are said to be able to distinguish between different calls made by potential predators, giving them an idea of when is best to emerge.

More than 50 wild eastern grey squirrels in public parks and residential areas were monitored in Ohio, where researchers simulated possible danger by playing a recording of a dangerous red-tailed hawk.

That clip was followed by songbird chatter or ambient sounds lacking bird calls, and the behaviour of each squirrel was monitored for a further three minutes.

In another study with the eastern ground squirrel, one researcher observed a squirrel jumping more than 8 feet between a tree stump and a feeding platform, propelling itself 10 times the length of its body. Flying squirrels, obviously, can traverse much farther distances midair—the northern flying squirrel, for instance, can glide up to 295 feet [PDF].
Published in the Plos One journal, the study found every squirrel showed heightened predator vigilance after hearing the hawk - including behaviours such as freezing, looking up or fleeing.

Those who heard the bird chatter playback afterwards displayed less anxiety and returned to normal levels of watchfulness more quickly than squirrels who did not hear the more peaceful sounds.

According to the team behind the research, the results suggest squirrels are able to tap into the casual chatter of many bird species as an indicator of safety.

"We knew that squirrels eavesdropped on the alarm calls of some bird species, but we were excited to find that they also eavesdrop on non-alarm sounds that indicate the birds feel relatively safe," the authors said.

"Perhaps in some circumstances, cues of safety could be as important as cues of danger."
