Mariana Crow Will Go Extinct in 75 Years, Study Suggests
Researchers from the University of Washington say the Mariana crow, a forest crow living on Rota Island in the western Pacific Ocean, will go extinct in 75 years. The extinction could happen almost twice as soon as previously believed. The crow’s extinction can be prevented with a bird management program that focuses on helping fledgling birds reach their first birthday, said James Ha, UW research associate professor in psychology. Ha examined survival rates in 97 Mariana crows — Corvus kubaryi — that had been tracked between 1990 and 2010 by researchers. He found that 40 percent of fledgling crows made it to their first birthday. The rapid decline of young birds is twice what researchers previously estimated.
