In his article, Bales recaps the story of James Tanners' famous 1938 photographs of an Ivory-billed woodpecker nestling taken while Tanner had the young bird out of the nest for banding. Two of these photographs were published in Tanner's dissertation in 1942, and, along with four others, were thought to be the only images in existence.
