What is the good thing bats do?

Answer 1

Among mammals, flight is a behavior unique to bats. Two other behaviors, echolocating and hanging upside down, are associated with bats, but not characteristic of them. Not all bats echolocate and not all bats use echolocation the same way. Furthermore, the echolocation calls of many species of bats are ultrasonic, which, by definition, is beyond the range of human hearing. But many species of bats echolocate with sounds readily audible to people. Bats also use vocalizations in many social situations, and their social calls are often quite audible to people. Male fruit bats in Africa (African epauletted bats [genus Epomops]; epauletted fruit bats [genus Epomophorus]; hammer-headed fruit bats [Hypsignathus monstrosus]) call to attract females. Pipistrelles (Pipistrellus pipistrellus) use harsh-sounding calls to discourage others from feeding in small patches of insects. Greater spear-nosed bats (Phyllostomus hastatus) have group-specific screech calls that keep group members together. Researchers are only just beginning to explore the many ways in which bats use vocalizations. When roosting, many bats hang upside down. This distinctive behavior makes take-off very easy: the bat just lets go, drops, and starts to fly. Hanging upside down may reflect specialization of the forelimbs as wings and attachments of wing membranes to the hind legs. Many other species of bats roost horizontally, their abdomens against the substrate. These bats, notably some species of free-tailed bats, are quite mobile on the ground, readily running or crawling. Compared to bats that probably never operate on the ground (e.g., some horseshoe bats), free-tailed bats have robust hind limbs, particularly thighbones (femora). Still other bats, for example, Spix's disk-winged bats (Thyroptera tricolor, family Thyropteridae), roost head-up.

They eat a lot of mosquitoes everyday which helps prevent the spread of diseases that can be caused by mosquito bites.
