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).
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.

Learned vocalizations have been identified in groups including whales, elephants, seals, and primates, however the most well-established examples of learned singing is in birds. [29] In many species, young birds learn songs from adult males of the same species, typically fathers. [30] This was first demonstrated in chaffinches (Fringilla coelabs).
Two birds preferred Bach and Vivaldi over Schoenberg or silence. The other two birds had varying preferences among Bach, Schoenberg, white noise and silence. [13] The greater honeyguide has a specific call to alert humans that it can lead them to honey, and also responds to a specific human call requesting such a lead. By leading humans to ...
Amphibian vocalization; Bird vocalization, bird calls and bird songs; Dolphin vocalizations; Female copulatory vocalizations, produced by females while mating; Voice (phonetics), the vibration of the vocal cords that accompanies some speech sounds Consonant voicing and devoicing, the addition or removal of this vibration from consonant sounds
Birds learn their songs from those made by other birds. In several examples, birds show highly developed repetition abilities: the Sri Lankan Greater racket-tailed drongo (Dicrurus paradiseus) copies the calls of predators and the alarm signals of other birds [57] Albert's lyrebird (Menura alberti) can accurately imitate the satin bowerbird ...
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 ...
Such auditory feedback is known to maintain the production of vocalization since deafness affects the vocal acoustics of both humans [17] and songbirds [18] Changing the auditory feedback also changes vocalization in human speech [19] or bird song. [20] Neural circuits have been found in the brainstem that enable such reflex adjustment. [21]
