Question

He knew his colors and shapes, he learned more than 100 English words, and with his own brand of one-liners he established (确立) himself in TV shows, scientific reports, and news articles as perhaps the world’s most famous talking bird.

But last week, Alex, an African parrot, died, obviously of natural causes, said Dr Irene Pepperberg, an expert at Brandeis University and Harvard who studied and worked with the parrot for most of its life and published reports of his progress in scientific journals. The parrot was 31.

Scientists have long debated whether any other species can develop the ability to learn human language. Alex’s language ability was, in some ways, more surprising than the efforts of those animals that have been taught, like Koko, the gorilla (猩猩) trained by Penny Patterson at the Gorilla Foundation in Woodside, or Washoe, another gorilla studied by R. Allen and Beatrice Gardner at the University of Nevada in the 1960s and 1970s.

When Dr Pepperberg, who was then a doctoral student in chemistry at Harvard, found Alex was good at remembering words in a pet store in 1977 and bought it, scientists had little expectation that birds could learn to communicate with humans. Most of the research had been done on pigeons, and was not promising.

But by using novel methods of teaching, Dr Pepperberg taught Alex to learn about 150 words, which he could put into categories. He could count small numbers and tell colors and shapes. “The work changed the way we think of bird brains,” said Diana Reiss, a psychologist at Hunter College who works with dolphins and elephants. “We used to look down upon those birds, but now we look at those brains — at least Alex’s — with some awe.”
