How does the Passenger pigeon behave?

The Passenger pigeon was known for its highly social behavior, often forming massive flocks that could number in the millions. These birds engaged in complex social interactions, including cooperative breeding and synchronized nesting. They primarily foraged for food in trees, feeding on seeds, fruits, and nuts, and were known for their strong, swift flight. Unfortunately, their gregarious nature contributed to their rapid decline due to overhunting and habitat loss in the 19th century.
