The Passenger Pigeon

Not very long ago, there used to be millions and millions of passenger pigeons in North America. They got their name because they often used to travel to new places to look for food. They flew very quickly in large flocks. These flocks were sometimes so big they blocked out the sun. Passenger pigeons lived in oak and beech forests. In the 1850s people began to cut down the forests to make way for farms. The birds'
nesting places were destroyed. Hunters killed millions for food. The last passenger pigeon was seen in 1914.
