Alex the parrot's last experiment shows his mathematical geniusThis is pretty amazing stuff.
Even in death, the world's most accomplished parrot continues to amaze. The final experiments involving Alex, a grey parrot (Psittacus eithacus) trained to count objects, have just been published.
They show that Alex could accurately add together Arabic numerals to a sum of eight and three sets of objects, putting his mathematical abilities on par with (and maybe beyond) those of chimpanzees and other non-human primates.
And:
In 12 trials of the Arabic numeral addition task, when asked "How many total?" he indicated the correct sum 9 times, demonstrating that 3 + 4 is 7, 4 + 2 is 6, 4 + 4 is 8 and so on. When presented sequentially with three sets of objects hidden under three cups, and asked how many, Alex offered the correct answer eight out of 10 times. He determined, for instance, that one, two and one jelly beans adds up to four.
Devious, treacherous, murderous, neanderthal, sub-human of the West.
