Critical Period for Song Learning

A species-specific developmental time window in which juvenile songbirds are especially sensitive to auditory input and are able to readily memorize the song patterns of conspecific adults.
Songs are an essential trait of songbirds and serve multiple communicative functions. They are used, more commonly, by males to attract and stimulate the reproductive behavior of females, to advertise territory ownership, and to mediate competition between rival males (Collins 2004). Although the process of song learning in songbirds has attracted attention and received contributions from several fields, including ethology, behavioral ecology, genetics, and neurobiology, it still stands as a major evolutionary puzzle. Song learning has drawn so much scientific interest, in part, due to its similarity to the process of language acquisition. Songbirds share with humans the very distinctive ability of vocal...
