In birds with song repertoires, individuals may share the same song type and use these song types for more complex communication. [23] Some birds will respond to a shared song type with a song-type match (i.e. with the same song type). [24] This may be an aggressive signal; however, results are mixed. [23]
For song learning to occur properly, young birds must be able to hear and refine their vocal productions, and birds deafened before the development of subsong do not learn to produce normal adult song. [34] The sensitive period in which birds must be exposed to song tutoring varies across species, but typically occurs within the first year of ...
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 ...

Passerine birds produce song through the vocal organ, the syrinx, which is composed of bilaterally symmetric halves located where the trachea separates into the two bronchi. Using endoscopic techniques, it has been observed that song is produced by air passing between a set of medial and lateral labia on each side of the syrinx. [1]

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 ...
While almost all living birds give calls of some sort, well-developed songs are only given by a few lineages outside the songbirds. And still, not all songbirds proffer a call that is distinctly melodious. Songbirds do, however, possess a highly developed vocal organ, the syrinx, that enables their sonorous activity. This organ, also known as a ...
