How do you get a Pidgey in Pokemon Omega Ruby?

In Pokémon Omega Ruby, you can catch a Pidgey by searching in the tall grass areas of Route 110 and Route 111. Pidgey typically appears at a low encounter rate, so be prepared to encounter other Pokémon as you search. Additionally, you can use a Pokémon with abilities that increase encounter rates to improve your chances. Keep an eye out for the Pokémon's silhouette in the grass to spot it more easily.
