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 ...
Animal navigation is the ability of many animals to find their way accurately without maps or instruments. Birds such as the Arctic tern , insects such as the monarch butterfly and fish such as the salmon regularly migrate thousands of miles to and from their breeding grounds, [ 1 ] and many other species navigate effectively over shorter ...
Animal echolocation, animals emitting sound and listening to the echo in order to locate objects or navigate; Echo sounding, listening to the echo of sound pulses to measure the distance to the bottom of the sea, a special case of sonar; Gunfire locator; Human echolocation, the use of echolocation by blind people; Human bycatch
Smaller animals like insects use different techniques as the separation of the ears are too small. [27] For the process of animals emitting sound to improve localization, a biological form of active sonar , see animal echolocation .
Animal echolocation, non-human animals emitting sound waves and listening to the echo in order to locate objects or navigate. Human echolocation , the use of sound by people to navigate. Sonar ( so und n avigation a nd r anging), the use of sound on water or underwater, to navigate or to locate other watercraft, usually by submarines.
Birds also use different sounds, songs and calls in different situations, and recognizing the different noises is essential to determine if a call is warning of a predator, advertising a territorial claim or offering to share food." [30] "Some birds, most notably oilbirds, also use echolocation, just as bats do. These birds live in caves and ...
Dogs do not make use of direction of gaze or exhibit left gaze bias with other dogs. A new approach in the 21st century in the field of animal communication uses applied behavioural analysis, specifically functional communication training. This form of training previously has been used in schools and clinics with humans with special needs, such ...
The moth Bertholdia trigona is one of several moth species known to jam the echolocation of its predator. Many tiger moths produce ultrasonic clicks in response to the echolocation calls bats use while attacking prey. [11] For most species of tiger moth these clicks warn bats that the moths have toxic compounds that make them distasteful. [12]
