What animal became extinct after 1973?

The passenger pigeon, once abundant in North America, is one of the most notable animals that became extinct after 1973. The last known individual, named Martha, died in captivity at the Cincinnati Zoo on September 1, 1914. Despite extensive conservation efforts, the species could not recover due to habitat loss and relentless hunting. The extinction of the passenger pigeon serves as a poignant reminder of the impact of human activity on wildlife.
