Population trends are based on the Red List of Threatened Species. The super-scripted "IUCN" tag is a link to that species's Red List of Threatened Species page. If a species has taxonomic synonyms, a list of these is provided in the "Scientific name" column, underneath the binomial name and author, based on the book Mammal Species of the World.

This can be used to estimate the speed of a flying bat or to identify bats which are echolocating while roosting. A bat call from a bat approaching or departing at 6.8 metres per second (15 mph) calling at 50 kHz will typically show a doppler shift of +- 1 kHz and pro rats. This can cause uncertainty with some species such as Pipistrelles.
The Ann W. Richards Congress Avenue Bridge, which crosses over Lady Bird Lake in Austin, Texas, is the world's largest urban bat colony. Seventeen species of bats live in the Carlsbad Caverns National Park, including a large number of Mexican free-tailed bats. [1]
The Indian flying fox (Pteropus medius), also known as the greater Indian fruit bat, is a species of flying fox native to the Indian subcontinent. It is one of the largest bats in the world. It is of interest as a disease vector, as it is capable of transmitting several viruses to humans.

Low-flying bats are vulnerable to crocodiles. [179] Twenty species of tropical New World snakes are known to capture bats, often waiting at the entrances of refuges, such as caves, for bats to fly past. [180] J. Rydell and J. R. Speakman argue that bats evolved nocturnality during the early and middle Eocene period to avoid predators. [178]
