Iggy the Passenger Pigeon
Status: Species known to science.
Extinct 1933.

Not so long ago, there were literally billions of Passenger Pigeons. Sometimes two billion Passenger Pigeons would fly together - the largest flock was a mile (1.6 km) wide and 300 miles (500 km) long, which would take several days to pass over. It almost seemed impossible to think of a day when passenger pigeons would not be around. But gradually their numbers started to dwindle as thousands were killed at a time in great shoots.

Finally, there were only about a quarter of a million wild Passenger Pigeons left, which were all killed in a single day in 1896 by sport hunters, who knew they were shooting the last wild flock. The last wild Passenger Pigeon was shot by a young boy in March 1900.

Not surprisingly on Infinity, Iggy, the last Passenger Pigeon, doesn't like humans at all.

Reason for Extinction:

Hunted by humans.
