Abstract
Eight parakeets (Melopsittacus undulatus), four from 1 to 2 months old and four from 9 to 12 months old, were taught to discriminate between a circle and a triangle in a Y-maze using a non-correction procedure. Although no age differences were found, all the birds met the stringent criterion for learning of 15 consecutive correct responses. It was concluded that the parakeet would make an interesting subject for further study.
