The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...
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.
Because evening bats do not enter or hibernate in caves, the species is not at-risk from white-nose syndrome, which has killed over six million bats in the United States since 2006. [21] The evening bat's avoidance of this disease, along with die-offs of many other species, is possibly responsible for the evening bat recently expanding its ...
[48] [49] Big brown bats tolerate cold weather fairly well, [46] although they can be negatively affected by major changes in temperature. [45] It is fairly common for some hibernating big brown bats to awaken temporarily and seek warmer shelter, locate water, and even mate. [8] [45] Big brown bats come out of hibernation in the spring.

When hunting, it often starts flying in early dusk, earlier than most European bats. It flies high above the forested areas that are its preferred habitat, reaching speeds of up to 50 km/h (31 mph). [21] Common noctule bats mainly eat beetles, moths and winged ants. It is known for its high-flying foraging technique, often hunting at altitudes ...
The species is very active at night, spending 6–7 hours flying a night for a total distance of about 14.9 miles (24.0 km). [3] Its long, narrow wings allow the bat to maintain flight at high speeds for long periods of time. These bats can reach heights of 196 feet (60 m), though they are also observed flying closer to the ground. [9]
Pallid bats are insectivores that feed on arthropods such as crickets, and are capable of consuming up to half their weight in insect every night. Pallid bats are gleaners, capturing prey from the ground and transporting it to their night roost for consumption. When foraging, pallid bats typically fly at low heights of 1–2 m off the ground.
