Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .
Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs (often simply birdsong ) are the bird sounds that are melodious to the human ear. In ornithology and birding , songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations).
Individual birds may be sensitive enough to identify each other through their calls. Many birds that nest in colonies can locate their chicks using their calls. [64] Alarm calls are used to sound alarm to other individuals. Food-begging calls are made by baby birds to beg for food, such as the "wah" of infant blue jays. [65]
The lyrebird is an Australian species best known for its ability to mimic man-made sounds. National Geographic has recorded these remarkable birds mimicking such unnatural noises as a chainsaw and ...
Located at the base of a bird's trachea, it produces sounds without the vocal folds of mammals. [1] The sound is produced by vibrations of some or all of the membrana tympaniformis (the walls of the syrinx) and the pessulus, caused by air flowing through the syrinx. This sets up a self-oscillating system that modulates the airflow creating the ...
Bird flight is the primary mode of locomotion used by most bird species in which birds take off and fly. Flight assists birds with feeding, breeding , avoiding predators , and migrating . Bird flight includes multiple types of motion, including hovering, taking off, and landing, involving many complex movements.
In this test, an anesthetized bird is presented with a single sound or a sequence of sounds, followed by an electric shock. The bird's heart-rate will increase in anticipation of a shock. Therefore, a measure of the heart-rate can determine whether the bird is able to distinguish between stimuli that would be followed by a shock from stimuli ...
According to the ACP the industry recognizes and studies the impact wind turbines have on birds. "Even with its relatively low impacts, the U.S. wind industry holds itself to a higher standard and ...
