Today, let us get to know the ten largest birds in existence and learn about the magical world of these "heavyweight" feathered friends!

Origin of Birds: Flying Dinosaurs

The history of birds can be traced back to the late Jurassic period 150 million years ago. At that time, their ancestors were theropod dinosaurs, such as the famous Archaeopteryx, which has the characteristics of both birds and dinosaurs, allowing us to glimpse how birds evolved from dinosaurs. In fact, scientists even quipped that "dinosaurs didn't really go extinct, they just found a way to survive and land on your windowsill."
