Here is a more detailed explanation of how robins fly:
1. Flapping: Robins flap their wings to create lift and propel themselves forward. When they flap their wings down, they create a powerful downdraft that pushes against the air and propels them upward. When they flap their wings up, they pull themselves forward through the air.
2. Gliding: Robins can also spread their wings and glide, which allows them to cover long distances without expending too much energy. When they glide, they use the lift generated by their wings to stay airborne and the momentum generated by their flapping to propel themselves forward.
3. Tailfeathers: Robins also use their tailfeathers to help them fly. Their tailfeathers help them steer and balance while they are in the air.
Robins are able to fly because they have a unique combination of physical characteristics, including long and pointed wings, strong flight muscles, and a lightweight body. These features allow them to generate lift and propel themselves through the air with great speed and agility.
