In the past, research on animal language development has focused on primates. It has been recently examined that the avian species may show similar language development. A similar past study done by the same researcher analyzed the similarities in language and object development to past studies using an African Grey parrot, by using a Green Cheek conure. The results showed that the Green Cheek conure used a similar proportion of object and language combinations. This suggests that the development of verbal and object combinations is not limited to the African Grey parrot, and may be more general to the parrot species. This furthers the suggestion that combination language development is not limited to the primate line. In the current study, a survey is used to analyze the language and object combinations of a lager variety of parrots with a sample of 19 birds.
