The Passenger Pigeon

Ecology and Behavior

This bird, when alive, was a migratory bird that populated North America. It depended greatly on the rest of its flock, often swarming prey and protecting each other by sheer numbers. Their role in the environment would be small, if not for the huge population size. As it was, because of their diet and communal roosting grounds. They played a big part in the dispersal of seeds and, unexpectedly, the destruction of trees. Caused by them choosing there to roost, they would cover the trees and branches would snap under their combined weight. So, when they finally did go extinct the impact on the restbv of the environment was somewhat lackluster considering that billions of animals ahd been killed. But the two effects they had caused in life somewhat balanced each other out, so when they left, drastic change didn't occur.

Initial Population

3-5 billion in the 1700s






Habitat distruction

The passenger pigeon once was numerous invincible species. But after constant years of over hunting, destruction of roosting grounds, and tracking them, never letting them escape, the once mighty pigeon finally gave up. The species finally extinct. The ease at which we could've prevented this is ridiculous, just take away one of the three horrors we committed and due to the initial size of the pigeon, would've been able to survive. But greed overwhelmed the hunters of this bird, and they never stopped their massacre, until the once numerous flocks were all gone.
