About Passenger Pigeons
The Passenger Pigeon Is an extinct American bird named after the french word Passenger for "passing by." Passenger Pigeons was an important source of food for the people of the mid-1800's. Rail roads had opened new opportunities for pigeon hunters. A single flock of Passenger pigeons could have 2 billion or more birds and there were multiple flocks of birds in the United States. One day the sky went black by birds for three days. This caused people to shoot the birds so they became extinct.
