Document Summary
Structure of the brain involved in singing behavior. These areas of brain are similar to other birds that are not songbirds. Vocal behavior of songbirds similar to how parrots can replicate sounds of humans. Why do songbirds sing: to attract females reproductive function; sound transmits through environment and catches attention of female, to alert other males aggressive signal; to keep other males from being around the female, secure territory. Development of the song: key feature of songbird system: through developmental process, songbirds can also replicate sounds. Sensory phase: little hat(cid:272)hli(cid:374)g (cid:271)ird i(cid:374) (cid:374)est hears his father"s so(cid:374)g or if you (cid:271)ri(cid:374)g it i(cid:374)to (cid:272)apti(cid:448)ity a(cid:374)d tutor teaches a song, the hatchling will hear it (sensory, auditory feature) and process it. Sensory motor phase: then bird has motor component where it produces sounds far into future (encoded song in memory and begins producing sounds that in turn hears and go from sensory to sensory motor phase (output)
