All About Ratites
Ratites are flightless yet faster than many other animals. With their strong legs, they can even pose a threat to lions! Learn all about them!
What Are Ratites?
Ratites have wings but are unable to fly. Instead, they possess strong legs that allow them to run swiftly. The most famous among them is the ostrich, which is the fastest bird on land and also the largest and heaviest. However, there are also smaller flightless birds like the kiwi.
Main Characteristics of Ratites
1. They Are Flightless
Even if ratites were to flap their wings rapidly, they would still be unable to take off. This is because their bodies are too heavy and their wings are too small. Additionally, they lack the necessary muscle strength.
2. They Have Strong Legs
When ratites are surprised by a predator, they try to escape by running away. If that fails, they defend themselves by kicking with their powerful legs. An ostrich can even kill a lion this way. The kiwi also has strong legs but cannot run as fast. Before domestic cats and dogs were introduced, it had no enemies to flee from.
3. They Are Ground-Nesters
Ratites live exclusively on the ground. Naturally, they do not build their nests in trees. Instead, they create shallow nests on the ground where they lay their eggs. Among all birds, ostriches lay the largest and heaviest eggs.
