Animals known to be highly intelligent, such as ravens and chimpanzees, have good long-term memory – and now it seems that some bats do too-

This is a sign of intelligent design, The one who maid them use of techniue of echolocation or that  bats used frequencies above the range of human hearing could also make them remember words, 

When fringe-lipped bats learn the sound of a dinner bell, they remember it for years. The bats’ enduring memory is comparable to that of other animals renowned for their expansive cognitive skills, such as crows and primates.

Fringe-lipped bats (Trachops cirrhosus) are native to rainforests in the Central and South American tropics. They are  noctural predators with a broad diet, snatching up insects, frogs, lizards and small mammals. The bats have a keen ear and are able to discern between the calls of poisonous animals.

Darwinists claim that a tiny ear bone has led to two bats evolving into two species

Darwinists claim that a tiny ear bone has led to two bats evolving into two species. they say that the groups diverged tens of millions of years ago. this  “may have led the two groups to evolve different forms of echolocation and even lifestyles.”

But both groups have relied to echolocation. And bats have always been batsas they were created by God,

Bats Use There sounds To ecolocate

Bats ae one of the creatures we admire most. First, they utter ecolocate. Science tells us that the mother of all bats could probably like modern bats.

Some bat prey have also developed the ability to hear bats' sounds and take evasive action, setting up a relentless battle of who hears who first. They utter ultrasound which we can’t do.

Bats also use neurons to find their way in total darkness.

“Ultrasound doesn't actually travel very far in air, though, so most bats have to really belt their echolocation calls out in order to have enough sound range to avoid flying into an object before they detect it or to find a tiny insect in front of them. It's sort of like headlights on a car — bright lights are needed to drive fast. Faster bats must be loud and have their sound travel far. 

This results in another problem. The sounds bats make can be absolutely deafening to bats themselves — the equivalent of holding a shrieking smoke detector up to your ear if the sound were within human hearing range. Bats generate these really loud sounds right next to their own ears so how do they not deafen themselves? “

Bats use their middle ear muscles to essentially "close their ears" while they are sending out sound waves. Of course, to hear the reflected sound waves, they must quickly re-open their ears. Bats can do this 10 times per second. Interestingly, some bat prey have also developed the ability to hear bats' sounds and take evasive action, setting up a relentless battle of who hears who first. “
