Bats use a type of "sonar" to locate objects even in the dark (echo-location). A bat makes a high-pitched noise that bounces off objects nearby and the bat hears the echo. By timing how long it takes for the bat to hear the echo, it can calculate how far away it is. When it comes to a flying insect, the bat listens to the echo of it's noises and is able to locate where an insect is. Then it can fly to the insect and catch it - even if it is pitch dark.
They use echo location. It is tiny beeps, too high pitched for our ears, and dogs ears too! The bats let out the tiny beeps, and the echoes tell them where bugs are.
Echo Location really is the answer
Bats emit high-frequency sound waves that bounce off the insect and return as echoes. By analyzing the time it takes for the echoes to return, bats can determine the distance of the insect based on the speed of sound in air and the time delay of the echo. This helps bats navigate and successfully catch their prey in the dark.
Most bats catch prey using their ears through a process called echolocation. They send out a high pitch (high frequency sound) which is above the human hearing range, and this sound echos off of their surroundings. Their ears are designed to catch this echo, and then they process the echos to get a sort of "mental image" of their surroundings. See Related Links for more info.

Their echolocation consists of tiny beeps, too high-pitched for our ears, and the echoes tell them where bugs are. Bats are not actually blind! Bats can actually see very well but at night they use echolocation. This process enables bats to emit sounds from their mouths that bounce off objects and allow them to avoid the objects when flying.
The kangaroo does not use its ears to catch anything. To begin with, the ears are not prehensile, and all they can do is rotate to listen carefully for predators. Secondly, very few species of kangaroos are anything but omnivores. No doubt the bettongs and musky rat-kangaroos which are omnivores use their ears to carefully listen for the movement of invertebrates, but that is completely the extent to which any kangaroo will use its ears for catching food.
i think the uestion you are asking is what do bats use their ears for. well the use there ears to sonicly see where they are going. the use is for hearing the massive screecth noises. and by the time the sound comes back it basicly makes a 3D image of its surroundings.
an elephant and an insect eating bat.
You can use your hands to grab and insect. You can also use bug catchers.
the ears
They HEAR using their ears but they use the echoes of the sounds they make to build a "sound picture" of their surroundings. This is used to avoid collisions and to catch prey. This use of sound and echoes is called "echo location".

When they cannot see insects, at night, they can still locate them by emitting a sound and listening for echoes coming off the insects, a process called echolocation. It also helps them to avoid flying into walls or other obstacles.
