Swellow is a large, dark-blue bird Pokémon with a red breast and face. A crest of feathers sweeps back from the top of its head. A blue stripe separates the red markings on its head and chest, and it has a white underside. It has small, narrow eyes, a pointed, yellow beak, and red feet with black talons. Each foot has three forward-facing toes and one pointed backward. Two long, pointed feathers with red tips form its tail and are an indication of good health when standing up straight. Swellow's wings taper to a sharp point. An impressive dive-bomber, it will never miss its target. Additionally, it takes great pride in its glossy plumage and often cleans the wings of other Swellow. It searches for warm meadows while in the air. Swellow preys on Wurmple.
In That's Just Swellow, Ash Ketchum's Taillow evolved into a Swellow during the final round of the Crossgate PokéRinger competition.
In Sky High Gym Battle!, Winona used a Shiny Swellow during her Gym battle against Ash. It faced off against Grovyle, which it was able to defeat, but it was later defeated by Ash's own Swellow.
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.
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.
