David W. Steadman of the New York State Museum said Thursday that a study of 4,000-year-old fossils shows that perhaps as many as 1,600 birds species disappeared forever within a few centuries of the arrival of humans in Polynesia, Micronesia and other island groups in the Pacific. Steadman's study was published in the journal Science.

The fossils, he said, show that prehistoric pioneers, some of whom paddled canoes for thousands of miles to settle in remote islands, brought with them pigs, rats and dogs that contributed to the extinction of many birds.
