Ancient bird from dinosaur era looked like a duck and quacked like one too, say experts

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.

“We can now say that it’s most probable that this bird... imitated a sound that can be compared to its living relatives, ducks and geese,” Argentine paleontologist Fernando Novas said at a news conference in Buenos Aires on Wednesday after the team published their conclusions in the journal Nature.

“The importance of this discovery is that it lets us ascertain how the dinosaurs, including birds, evolved in the way they communicated with each other and how this organ that was capable of emitting sound, permitted brain development.”

The fossils of the bird from the Cretaceous-age were first found in 1992 by members of Argentina’s Antarctic institute and were detailed as a new species in a 2005 study that linked them to modern ducks and geese. The study was also published in Nature and led by Julia Clarke, a professor of vertebrate palaeontology at the University of Texas at Austin.

A model of the bird presented at the Buenos Aires conference closely resembled a modern duck.
