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).
Musicologists such as Matthew Head and Suzannah Clark believe that birdsong has had a large though admittedly unquantifiable influence on the development of music. [2] [3] Birdsong has influenced composers in several ways: they can be inspired by birdsong; [4] they can intentionally imitate bird song in a composition; [4] they can incorporate recordings of birds into their works; [5] or they ...
Although most birds acquire song learning within the first year, brown-headed cowbirds have a delayed sensitive period, occurring approximately one year after hatching. [35] This may be an adaptation to prevent the young birds from learning the songs from the foreign bird species.
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 ...

In males, however, most song system neurons respond maximally to the sound of the bird's own song, even more than they do to the tutor's song or any other conspecific song. [6] [7] In HVC, neurons switch from responding best to tutor song (35–69 days post-hatch) to responding best to the bird's own song (>70 days post-hatch). [8]
In music, birdsong has influenced composers and musicians in several ways: they can be inspired by birdsong; they can intentionally imitate bird song in a composition, as Vivaldi, Messiaen, and Beethoven did, along with many later composers; they can incorporate recordings of birds into their works, as Ottorino Respighi first did; or like ...
Different aspects and features of bird song such as structure, amplitude and frequency have evolved as a result of sexual selection. [5] Large song repertoires are preferred by females of many avian species. [6] One hypothesis for this is that song repertoire is positively correlated with the size of the brain's song control nucleus (HVC). A ...
