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).
The syrinx (from the Greek word "σύριγξ" for pan pipes) is the vocal organ of birds. 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 ...
Lateral dominance of the hypoglossal nerve conveying messages from the brain to the syrinx was first observed in the 1970s. [3] [4] This lateral dominance was determined in a breed of canary, the waterschlager canary, bred for its long and complex song, by lesioning the ipsilateral tracheosyringeal branch of the hypoglossal nerve, disabling either the left or right syrinx.
Vocal Bird anatomy: Birds produce sounds through the air that passes through the Syrinx, which is shown close up in the bottom right. In order for birds to produce sound, they use an organ located above the lungs called the syrinx , which is composed of tracheal rings, syringeal muscles, Tympaniform membrane, and internal bony structures that ...
