Note 1

The Passenger Pigeon, Ectopictes migratorius, was sometimes called the "wild pigeon" or "American pigeon." Its phenomenal numbers were described by Audubon and other naturalists of the 19th Century. Some ornithologists estimate that there were as many Passenger Pigeons as all other birds in the Americas combined: it was the most abundant bird in the world. It was severely reduced in numbers by systematic and massive market-hunting, and by habit destruction (the cutting of old forests). Adapted to life in large flocks, the species was unable to maintain itself in small, scattered bands, and steadily decreased even after market-hunting had become unprofitable. It is possible that the introduction of diseases from domestic pigeons may also have played a part in the demise of this remarkable species. The last individual Passenger Pigeon was "Martha," a captive specimen in the Cincinnati Zoo, who died in 1914.
