Mathematical Parrot Reveals His Genius With Posthumous Paper
ananyo writes "Even in death, the world's most accomplished parrot continues to amaze. The final experiments involving Alex – a grey parrot trained to count objects – have just been published (abstract). They show that Alex could accurately add together Arabic numerals to a sum of eight, and correctly add three small sets of objects, putting his mathematical abilities on par with (and maybe beyond) those of chimpanzees and other non-human primates."
Alex was clearly pretty smart. However, it is as yet still unclear if Alex was actually a representative parrot or was smarter than other parrots. A lot of the current work being done will help answer that. There's also some concern that some of the early experiments with Alex didn't adequately handle the Clever Hahns problem- http://en.wikipedia.org/wiki/Clever_Hans where an animal rather than give actual answers uses subtle cues from the examiner on how to answer correctly. The more recent experiments help address that. It seems clear at this point that Alex's intelligence, and that of the other African Greys, is genuine, but what the average is like is still unclear. One thing is certain though: the use of the word "parrot" to mean mindlessly repeat is deeply unfair.
Corvids are as, or may even be more, intelligent. There's the classic story of the Caledonian crow who custom fashioned it's own tool to get at grubs, a trait previously only known to primates, to cite one example. Others abound, but I'm feeling too lazy right now to go hunt them down. Heckle and Jeckle would've outsmarted Wiley E. Coyote any day of the week.
