Acoustics of the songs of Mexican free-tailed bats [225] Bats are among the most vocal of mammals and produce calls to attract mates, find roost partners and defend resources. These calls are typically low-frequency and can travel long distances. [48] [226] Mexican free-tailed bats are one of the few species to "sing" like birds. Males sing to ...
Mexican free-tailed bats are nocturnal foragers and begin feeding after dusk. They travel 50 km in a quick, direct flight pattern to feed. This species flies the highest among bats, at altitudes around 3,300 m (10,800 ft). [3] Bats appear to be most active in late morning and afternoon between June and September. [25]
They are slender bats with unusually long tails and, as their name suggests, funnel-shaped ears. They are small, at only 3.5 to 5.5 cm (1.4 to 2.2 in) in length, with brown, grey, or reddish fur. Like many other bats, they are insectivorous, and roost in caves. [citation needed]

Unlike most bats, which bear only one pup per season, the western red bat can give birth to as many as four pups at once. [7] To compensate for larger litters, desert red bats have four nipples rather than two. The bats mate during August and September. Pups are born about 90 days after mating.
The Phyllostomidae, also known as New World leaf-nosed bats, are among the most ecologically diverse mammal families. [6] This variation is measured by diversity in skull morphology and diet-related characteristics: Phyllostomidae consists of species that have evolved physical modifications for insectivory, frugivory, hematophagy, nectarivory, and omnivory.
The gray bat (Myotis grisescens) is a species of microbat endemic to North America.It once flourished in caves all over the southeastern United States, but due to human disturbance, gray bat populations declined severely during the early and mid portion of the 20th century. 95% of gray bats now hibernate in only 15 caves.
