Mexican free-tailed bats are typically 9 cm (3.5 in) in length and weigh around 7–12 g (0.25–0.42 oz) with females tending to be slightly heavier than males by 1-2 grams for increased fat storage to use during gestation and nursing. [8]
Mexican free-tailed bat: 160 km/h (100 mph) [14] Flight It has been claimed to have the fastest horizontal speed (as opposed to stoop diving speed) of any animal. 7 Frigatebird: 153 km/h (95 mph) Flight The frigatebird's high speed is helped by its having the largest wing-area-to-body-weight ratio of any bird. 8 Rock dove (pigeon)
The fastest animal in flapping horizontal flight may be the Mexican free-tailed bat, said to attain about 160 kilometres per hour (99 mph) based on ground speed by an aircraft tracking device; [24] that measurement does not separate any contribution from wind speed, so the observations could be caused by strong tailwinds. [25] Slowest.

Mexican free-tailed bats are thought to be the fastest mammal on earth, capable of horizontal flight speeds over a level surface up to 160 km/h (100 mph). [32]
