When and where did the last known passenger pigeon die?

The last known passenger pigeon, a bird named Martha, died on September 1, 1914, at the Cincinnati Zoo and Botanical Garden in Ohio.1

The extinction of this species, which was once incredibly abundant across eastern North America, serves as a sobering reminder of the impact of human activity on the natural world. The mass slaughter of these birds by settlers, who hunted them by the millions, ultimately led to their demise and provided a significant impetus for the modern conservation movement.12
