which researcher trained an african grey parrot to answer spoken questions with spoken words
Alex (parrot) Alex (1976 – 6 September 2007)[1] was an African grey parrot and the subject of a thirty-year (1977–2007) experiment by animal psychologist Irene Pepperberg, initially at the University of Arizona and later at Harvard University and Brandeis University. When Alex was about one year old, Pepperberg bought him at a pet shop.[2] The name Alex was a backronym for avian language experiment,[3] or avian learning experiment.[4]
Cockatiel The cockatiel is the only member of the genus Nymphicus. It was previously considered a crested parrot or small cockatoo; however, more recent molecular studies have assigned it to its own subfamily, Nymphicinae. It is, therefore, now classified as the smallest of the Cacatuidae (cockatoo family). Cockatiels are native to Australia, and favour the Australian wetlands, scrublands, and bush lands.
