The "singing" of male cicadas is produced principally and in the majority of species using a special structure called a tymbal, a pair of which lies below each side of the anterior abdominal region. The structure is buckled by muscular action and, being made of resilin , unbuckles rapidly on muscle relaxation, producing their characteristic sounds.
Riodinids are known to make substrate borne sounds in two ways. While most singing riodinid caterpillars produce sound by scraping ribbed vibratory papillae against the rough surface of the head [1] [8] [9] [10] a few riodinids such as E. elvina, achieve the same effect by rubbing the cervical membrane (analogous to a neck) against the head.
A song sparrow singing in Delaware, USA. The sparrow species derives its name from its colorful repertoire of songs. Enthusiasts report that one of the songs heard often in suburban locations closely resembles the opening four notes of Ludwig van Beethoven's Symphony No. 5. The male uses a fairly complex song to declare ownership of its ...
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 .
Orthopteran insects, including crickets and katydids (family Tettigoniidae), have been especially well-studied for sound production. 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.
Tympanal organ on the tibia of the katydid Zabalius aridus Tympanal organ of two species of moths, ventral view of abdomen (Tineidae and Pyralidae). A tympanal organ (or tympanic organ) is a hearing organ in insects, consisting of a tympanal membrane stretched across a frame backed by an air sac and associated sensory neurons. [1]
An eastern towhee (Pipilo erythrophthalmus) singing, Jamaica Bay Wildlife Refuge, United States Blackbird song. 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.
The anatomical parts used to produce sound are quite varied: the most common system is that seen in grasshoppers and many other insects, where a hind leg scraper is rubbed against the adjacent forewing (in beetles and true bugs the forewings are hardened); in crickets and katydids a file on one wing is rubbed by a scraper on the other wing; in ...
