Never Underestimate the Intelligence of Birds

Cockatoos are recognizable by the showy crests and curved bills. These extremely social birds have endearing personalities and great speaking abilities. As a part of their extreme intelligence, is their ability to imitate a wide variety of sounds and speech. But more than that, when scientists performed intelligent tests with the captive bred Goffin's cockatoo they learned they are able to actually resist the temptation of eating a food item put in front of them in order to trade it for a better reward later.
