These insects use scraper-like structures on one wing to sweep over file-structures on an opposing wing to create vibrations, producing a variety of trilling and chirping sounds. [ 15 ] [ 16 ] Locusts and other grasshoppers (suborder Caelifera ) stridulate by rubbing hind legs against pegs on wing surfaces in an up and downward motion. [ 17 ]
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 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).
An annual International Dawn Chorus Day is held on the first Sunday in May [6] when the public are encouraged to rise early to listen to bird song at organised events. The first ever was held at Moseley Bog in Birmingham, England, in 1987, organized by the Urban Wildlife Trust (now The Wildlife Trust for Birmingham and the Black Country).
xeno-canto, which translates to "strange sound", is a sounds-only project seeking to highlight sounds of birds, rather than images or videos. xeno-canto was launched on May 30, 2005, by Bob Planqué, a mathematical biologist at VU University Amsterdam, and Willem-Pier Vellinga, a physicist who now consults for a global materials technology company.

Further studies show that rats chirp when wrestling one another, before receiving morphine, or when mating. The sound has been interpreted as an expectation of something rewarding. [10] High frequency ultrasonic vocalizations are important in rat communication and function to elicit approach behavior in the recipient. [11]
The archosaurian shift from larynx to syrinx must have conferred a selective advantage for crown birds, but the causes for this shift remain unknown. [10] To complicate matters, the syrinx falls into an unusual category of functional evolution: arising from ancestors with a larynx-based sound source, the syrinx contains significant functional overlap with the structure it replaced.
