Some of the birds are said to have certain sensitivities when it comes to hearing. For instance, there are owls that tend to have sensitivity towards the sounds that are smaller. Not to mention that the position of their ears (one is lower than the other) enables the owls to have perfect source location abilities. Apart from that, some birds like bats are able to use the ability of echolocation in order to travel from one place to another. Echolocation is the process of reading the signals from the sound waves that hit certain objects and bounce back to the source. Bats cannot see properly and hence echolocation proves to be a beneficial ability in their case.
