keyword: Was. swiped from the internet..“This bird roamed the skies of South America from about 6 million years ago up until about 10,000 years ago. The most likely reason for this disappearance is climate change. 10,000 years ago was the end of the last ice age, so the earth was going through a period of rapid warming. This and other factors, such as overhunting by humans, caused a mass extinction of the majority of the large animals in the Americas.”
