This is a synthesis of her studies. 330 $bCan a parrot understand complex concepts and mean what is says? Since the early s, most studies on animal-human communication have focused on great apes and a few cetacean species. Birds were rarely used in similar studies on the grounds that they were merely talented mimics -that they were, after all, "birdbrains". 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.;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. 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. 606 $aAfrican gray parrot$xBehavior 606 $aCognition in animals 606 $aAnimal communication 608 $aElectronic books. 615 0$aAfrican gray parrot$xBehavior. 615 0$aCognition in animals. 615 0$aAnimal communication. 676 $a598.71 686 $aWT 2030$2rvk 700 $aPepperberg$b Irene M$g(Irene Maxine)$0956341 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910454833503321 996 $aThe Alex studies$92165322 997 $aUNINA
