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.

In evolutionary biology, the Baldwin effect describes an effect of learned behaviour on evolution. James Mark Baldwin and others suggested that an organism's ability to learn new behaviours (e.g. to acclimatise to a new stressor) will affect its reproductive success and will therefore have an effect on the genetic makeup of its species through ...
Song learning in juvenile birds occurs in two stages: sensory learning, which involves the juvenile listening to the father or other conspecific bird and memorizing the spectral and temporal qualities of the song (song template), and sensorimotor learning, which involves the juvenile bird producing its own vocalizations and practicing its song ...
Bird song is an example of learned territorial defense. Studies show that birds with high-quality songs will use them as a stimulus to deter predators from their territorial range. [ 13 ] Higher quality songs have been proven to act as the best defense mechanism in a variety of bird species, such as the red-winged blackbird ( Agelaius ...
"Human Behaviour" is a song by Icelandic recording artist Björk, released on 7 June 1993 by One Little Indian and Elektra Records as the lead single from her debut studio album, Debut (1993). [2] Produced by Björk's longtime collaborator Nellee Hooper , it reflects upon human nature and emotion from a non-human animal's point of view .
The most famous of these eating behaviors was observed on the island of Koshima, where one young female was observed carrying soiled sweet potatoes to a small stream, where she proceeded to wash off all of the sand and dirt before eating. This behavior was then observed in one of the monkey's playmates, then her mother and a few other playmates.
One key distinction between imitation and emulation is copying fidelity. High-fidelity is associated with imitation. In studies comparing behaviors of chimpanzees and human children, the human children were typically shown to perform high-fidelity imitation, what may even be considered 'over-imitation.'
A behavior may be learned socially, but the fact that it was learned socially does not necessarily mean it will last. The fact that the behavior is rewarding has a role in cultural stability as well. The ability for socially-learned behaviors to stabilize across generations is also mitigated by the complexity of the behavior.
