ABSTRACT
To study vocal mimicry in captive Hill Mynah Gracula religiosa, four experiments were conducted to examine 1) factors of development influenced the ability of learning 2) prior residence determined the ability of producing vocal mimicry 3) vocalization manipulated the social dominance. It showed that birds were able to well imitate if were hand-reared individually when they were less than five weeks old. No matter how good birds could do vocal mimicry after learning, if they were put into the resident aviaries, they almost stopped producing vocal mimicry. Dominance, through the prior residence played the important roles in this matter. Prior residence effect overcame other factors in the case that even resident birds produced fewer times of vocal mimicry, they still dominated the newcomers which used to be fluently vocal mimicry producers. Nevertheless, in initial grouping, with unfamiliar birds, ones which originally produced more times in vocal mimicry, had more advantage to get dominant position in captivity. These suggested that although prior residence overrode vocal mimicry ability, vocalization, anyhow, which led birds to gain dominance.
