The Passenger Pigeon

The Museum has nine Passenger Pigeons including a beautifully mounted specimen, I always get drawn to this bird because of all extinct species, the Passenger Pigeon had the most spectacular demise, hurtling from a population of billions to a population of exactly zero in less than a hundred years. Why and how is a question I and others have asked many times.
The Passenger Pigeon or Wild Pigeon (Ectopistes migratorius) was abundant in North America until it was eradicated in the wild in 1900, then finally altogether on September 1st 1914 at 1pm. The only animal on Earth to have an exact time of extinction, the last Passenger Pigeon died in captivity in Cincinnati Zoo.
There were so many Passenger Pigeons in flocks that trees would often fall when they roosted and people compared there enormous sounds and screeches to “threshing machines running under full headway”. The flocks were so thick that hunting was easy—even waving a pole at the low-flying birds would kill some. Still, harvesting for subsistence didn’t threaten the species’ survival. But after the Civil War came two technological developments that set in motion the pigeon’s extinction: the national expansions of the telegraph and the railroad. They enabled a commercial pigeon industry to blossom, fueled by professional sportsmen who could learn quickly about new nestings and follow the flocks around the continent. The professionals and amateurs together out flocked their quarry with brute force. They shot the pigeons and trapped them with nets, torched their roosts, and asphyxiated them with burning sulphur. They attacked the birds with rakes, pitchforks, and potatoes. They poisoned them with whiskey-soaked corn. Ultimately, the pigeons’ survival strategy—flying in huge predator-proof flocks—proved their undoing.
