When we think of birds, we might picture graceful sparrows or eagles soaring through the sky. But did you know that on our planet, there are other birds whose astonishingly large size makes them veritable giants of the avian world? Today, let's get to know the ten largest living birds and explore the amazing world of these "heavyweight" feathered friends!
Origin of Birds: Descendants of Flying Dinosaurs
The history of birds can be traced back to the Late Jurassic period, 150 million years ago, when their ancestors were theropod coelurosaurs, such as the famous Archaeopteryx, which combined features of birds and dinosaurs, giving us a glimpse into how birds evolved from dinosaurs. In fact, scientists have even jokingly said, "Dinosaurs didn't really go extinct; they just survived in a different way and ended up on your windowsill."
