Tomorrow marks the centenary of the death of the world's last passenger pigeon, once North America's most numerous bird. A suitable short essay on its extinction can be found at http://e360.yale.edu/feature/fate_of_the_passenger_pigeon_looms_as_a_somber_warning/2797/ by Joel Greenberg, author this year of "A Feathered River Across the Sky: The Passenger Pigeon's Flight to Extinction," a stirring chronicle of this amazing bird's history, in which the villains are, lamentably, of our species, and our ignorance, greed, and insouciance. This still plays out: see some scary warnings at http://news.nationalgeographic.com/news/2014/08/140827-seabird-puffin-tern-iceland-ocean-climate-change-science-winged-warning/ . Good birding, Bill Whan Columbus ______________________________________________________________________ Ohio-birds mailing list, a service of the Ohio Ornithological Society.
