Abstract
Investigated the ability of the parrot to produce inarticulate sounds. One trained amazon parrot was observed and experimented upon. The parrot produces sounds either spontaneously or due to visual and auditory stimuli. The aim of the experiments was to determine the instinctive response of the bird, its ability to distinguish between pitch and timber, the role of imitation in its reaction, and the motive for the reproduction of noninstinctive sounds. The parrot was able to distinguish sounds of widely differing pitch and timber and to reproduce them. The bird's capacity for circular imitation could be developed in captivity. The impulse to imitate various sounds was hard to determine; it was probably connected to the sex life of the animal. The experiments were simple and without controls, hence the results are not reliable. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
