How Do Birds Fly? – Simple Lesson with Video & Quiz
Birds fly by flapping their wings. Their wings are designed to create lift and thrust, allowing them to stay airborne. They also have hollow bones which make them lightweight, enabling them to soar through the sky with ease.
Some birds like eagles and hawks use thermal currents to glide effortlessly, while others like hummingbirds can hover in place by rapidly flapping their wings.
Flying is essential for birds to search for food, migrate to warmer climates, and escape from predators.
