Ancient bird from dinosaur area probably sounded like duck

Scientists for years have known what birds living at the end of the age of dinosaurs looked like. Now, they say they might know what one sounded like: quack!

The team of scientists says the "Vegavis Iaai" bird that lived in Antarctica's Vega Island more than 70 million years ago probably sounded like a modern-day duck. They based their findings on unearthed fossils of the bird's sound-producing vocal organ known as the syrinx.

The team held a news conference in Buenos Aires on Wednesday after their conclusions were presented in the Nature journal.
