Description
Jie Ma, Robert Naumann, and Jagmeet Kanwal studied hearing in mustached bats for PLOS ONE in 2010. Bat calls contain rising and falling sweeps of pitch. The team asked how finely bats can tell one sweep pattern from another.
The researchers linked certain sweeps to a mild shock, then watched heart rate for signs of fear. Bats learned to react to the paired sweep and not to similar ones. Their choices showed very sharp hearing for small changes in pitch movement. Sharp hearing of this kind likely helps bats sort social calls from echoes in the dark.
