When you think of Australia, it's hard to not immediately think of its eclectic animals. You know the ones: jacked kangaroos, tarantulas, the inland taipan. But one bird that deserves more attention is the cockatoo.

Dinosaurs are often depicted as large beasts roaming through tropical forests or across hot deserts — and the humid jungle of Jurassic Park may have gone a long way to solidify those images.

A recent study of mummified parrots found in a high-altitude desert region in South America suggests to researchers that, as far back as some 900 years ago, people went to arduous lengths to transport the prized birds across vast and complex trade routes.

The remains of more than two dozen scarlet macaws and Amazon parrots were found at five different sites in northern Chile's arid Atacama Desert — far from their home in the Amazon rainforest.

So how did they get there?
