Can a parrot understand complex concepts and mean what is says? Birds were rarely used in similar studies on the grounds that they were merely talented mimics -that they were, after all, "birdbrains". Since the early s, most studies on animal-human communication have focused on great apes and a few cetacean species.
Twenty years ago Irene Pepperberg set out to discover whether the results of the pigeon studies necessarily meant that other birds -particularly the large-brained, highly social parrots - were incapable of mastering complex cognitive concepts and the rudiments of referential speech. Experiments performed primarily on pigeons in Skinner boxes demonstrated capacities inferior to those of mammals; these results were thought to reflect the capacities of all birds, despite evidence suggesting that species such a s jays, crows, and parrots might be capable of more impressive cognitive feats. her investigation and the bird at its centre - a male Grey parrot named Alex - have since become almost as well known as their primate equivalents and no less a subject of fierce debate in the field of animal cognition.
