The Story of the Passenger Pigeon

The story of the rapid and brutal extinction of the Passenger Pigeon, once so abundant that they ‘blotted out the sky’, until the last bird died on 1st September 1914. It is also an evocative story of wild America – the allure of its natural ‘productions’, its ruthless exploitation, and a morality tale for our times.
