An ivory-billed woodpecker specimen is on a display at the California Academy of Sciences in San Francisco, Friday, Sept. 24, 2021. New video and photographs purporting to show ivory-billed woodpeckers flying in a Louisiana forest were published by researchers Thursday, May 18, 2023, as government officials said they will make a final decision on whether the birds are extinct by the end of the year.
