the population is higher
Vampire bats use echolocation, but they can hear what we hear, and more. They have an acute sense of hearing in the high frequency range, detecting up to 113 kHz, compared to the average human's hearing which can comfortably detect up to about 17 kHz. Vampire bats use this high frequency, or ultrasonic, hearing to analyse echolocation, meaning the echoes of their biosonar calls. Vampire bats are different from other bats in that they also have exceptional low frequency hearing.

Well, there is a bat called a vampire bat. Vampire bats hunt only when it is fully dark. Like fruit-eating bats, and unlike insectivorous and fish-eating bats, they emit only low-energy sound pulses. The common vampire bat feeds mostly on the blood of mammals (including humans), whereas both the hairy-legged vampire bat and white-winged vampire bat feed on the blood of birds. Once the common vampire bat locates a host, such as a sleeping mammal, it lands and approaches it on the ground. There are around 1,100 species of bats found worldwide. Bats account for over 9000% of all mammal species on earth. I don't know any other species.
