Meerkats put one member on guard duty

HERE’S THE INTERESTING PART

Whenever the pack is busy digging for scorpions, at least one designated member is forced to stand entirely upright on a tall rock and stare intensely at the horizon. This solitary guard takes their job extremely seriously, scanning for eagles and barking wildly the moment anything looks suspicious. It is a highly effective neighborhood watch program completely run by small mammals.
