Pidgey

Pidgey is one of the types of Pokémon species. They are the first bird Pokémon featured in the National Pokédex, though other Pokémon including two bug types and Charizard have the ability to fly. In all, the species can evolve two times, first into Pidgeotto, then into Pidgeot once they reach a certain level. In the generation one video games, they are relatively common during the first stages of the game, though will soon be replaced by more powerful Pokémon once you progress through it.
