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 primary vocal organ of birds is called the syrinx, which is located at the fork of the trachea, and is not present in mammals. [9] As air passes through the respiratory tract , the syrinx and the membranes within vibrate to produce sound. [ 10 ]
However, sound propagates readily through water and across considerable distances. Many marine animals can see well, but using hearing for communication, and sensing distance and location. Gauging the relative importance of audition versus vision in animals can be performed by comparing the number of auditory and optic nerves .
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 ...

Vocal learning is the ability to modify acoustic and syntactic sounds, acquire new sounds via imitation, and produce vocalizations. "Vocalizations" in this case refers only to sounds generated by the vocal organ (mammalian larynx or avian syrinx) as opposed to by the lips, teeth, and tongue, which require substantially less motor control.

HVC is located in the caudal nidopallium.It projects to the song motor pathway via the robust nucleus of the arcopallium (RA) and to the Anterior Forebrain Pathway via the basal ganglia nucleus Area X. [1] It receives recurrent motor activity through the thalamic nucleus Uvaformis (Uva) and input from the auditory system through projections from the caudalateral mesopallium (CMM) and through ...
