Some bats become dormant during higher temperatures to keep cool in the summer months. [123] Heterothermic bats during long migrations may fly at night and go into a torpid state roosting in the daytime. Unlike migratory birds, which fly during the day and feed during the night, nocturnal bats have a conflict between travelling and eating.
Stellaluna keeps flying, but when her wings hurt, she stops to rest. When she does, she hangs by her thumbs. Soon other bats come, and one asks Stellaluna why she is hanging by her thumbs. As she tells the other bats her story, Mother Bat reunites with her and Stellaluna finally understands why she is so different.

Stem-bats such as Onychonycteris and Icaronycteris were already capable of flying and the latter was a laryngeal echolocator. Contrary to the hypothesis of multiple flight origins, which assumes a bat ancestor with only handwings and no plagiopatagia, embryonic development shows the plagiopatagium appearing before the dactyloptagium.
The bats send out the pulse approximately once every 200 ms, and the steep FM are used to locate obstacles or targets, allowing them to fly indoors. [2] In high latitude areas, female northern bats fly during daytime because of the short nights, but their foraging peaks after dusk and sometime before dawn.
Mexican free-tailed bats are primarily insectivores. They hunt their prey using echolocation. The bats eat moths, beetles, dragonflies, flies, true bugs, wasps, and ants. They usually catch flying prey in flight. [15] Large numbers of Mexican free-tailed bats fly hundreds of meters above the ground in Texas to feed on migrating insects. [16]
Vampire bats hunt at night, [18] using echolocation and olfaction to track down prey. [23] They feed in a distance of 5 to 8 km (3.1 to 5.0 mi) from their roosts. [ 24 ] When a bat selects a target, it lands on it, or jumps up onto it from the ground, [ 18 ] [ 24 ] usually targeting the rump, flank, or neck of its prey; [ 18 ] heat sensors in ...
