Swellow is very conscientious about the upkeep of its glossy wings. Once two Swellow are gathered, they diligently take care of cleaning each other's wings.
Swellow flies high above our heads, making graceful arcs in the sky. This Pokémon dives at a steep angle as soon as it spots its prey. The hapless prey is tightly grasped by Swellow's clawed feet, preventing escape.
