The aim of this study was to map the early vocal development of African grey parrots until age of 11 weeks. Another goal was to compare it theoretically with the early vocal development of children.After identifying the repertoire we used stage models of vocal development to theoretically compare the development of early vocalizations in children and parrots.
We identified several types of calls in the repertoire of parrots and we also found several vocalisation contexts which differ from usual contexts described in adult parrots. Regarding the comparison of vocal development, we have discovered that there are similar trends in early vocal ontogeny of African grey parrots and children.
