U.S. says ivory-billed woodpecker, 22 other species extinct

Associated Press

Death has come knocking the last time for the splendid ivory-billed woodpecker and 22 more birds, fish, and other species: The U.S. government recently declared them extinct. It’s a rare move for wildlife officials to give up hope on a plant or animal, but government scientists say they’ve exhausted to find these 23. And they warn climate change, on top of other pressures, could make such disappearances more common as a warming planet adds to the dangers facing imperiled plants and wildlife.
