WebEcholocation, also called bio sonar, is a biological sonar used by several animal species. ... animal echolocation has only one transmitter and two receivers (the ears) positioned slightly apart. The echoes returning to the ears arrive at different times and at different intensities, depending on the position of the object generating the echoes

WebAnimal cognition encompasses the mental capacities of non-human animals including insect cognition.The study of animal conditioning and learning used in this field was developed from comparative psychology.It has also been strongly influenced by research in ethology, behavioral ecology, and evolutionary psychology; the alternative name …

WebVisual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment. This is different from visual acuity, which refers to how clearly a person sees (for example …

WebDescription and ecology. The swift family remains one of the more complicated groups of birds in taxonomic research, but the swiftlet tribe is a rather well-defined group. Its internal systematics is confusing; the plumage is usually dull, with shades of black, brown, and gray; from their outward appearance, most species are very similar. Swiftlets have four toes, …

WebL'écholocalisation, ou écholocation, consiste à envoyer des sons et à écouter leur écho pour localiser, et dans une moindre mesure identifier, les éléments d'un environnement. Elle est utilisée par certains animaux, notamment des chauves-souris et des cétacés, et artificiellement avec le sonar.Ces animaux ont en commun une protéine particulière, la …

WebEcholocation is the process where an animal produces a sound of certain wavelength, and then listens to and compares the reflected echoes to the original sound emitted. Bats use echolocation to form images of their surrounding environment and the organisms that inhabit it by eliciting ultrasonic waves via their larynx. The difference between the …

WebHuman echolocation is the ability of humans to detect objects in their environment by sensing echoes from those objects, by actively creating sounds: for example, by tapping their canes, lightly stomping their foot, snapping their fingers, or making clicking noises with their mouths.People trained to orient by echolocation can interpret the sound waves …
