A carnivorous plant has learnt how to communicate with bats

It uses ultrasonic calls to entice bats to shit in it.

Scientists have discovered that a species of carnivorous pitcher plant in Borneo has evolved a unique way of enticing bats to roost nearby. But the end goal isn't to eat the flying mammals - instead, Nepenthes hemsleyana stays nourished by digesting their falling droppings.
So in other words, a plant has worked out how to communicate with a mammal, just to encourage it to poop in its mouth.
