Extinct birds are species that no longer exist anywhere on Earth. This can happen due to various reasons, including habitat loss, hunting, and climate change. Some well-known examples of extinct birds include the Dodo and the Passenger Pigeon. The extinction of these birds often serves as a reminder of the impact humans can have on wildlife. Conservation efforts today aim to protect endangered species to prevent further extinctions. Understanding the history of extinct birds helps scientists and conservationists work towards preserving the remaining bird species and their habitats.
