Pidgey is a small, plump-bodied avian Pokémon. It is primarily brown with a cream-colored face, underside, and flight feathers. Both its feet and beak are a pinkish-gray color. It has black, angular markings around its eyes and a small crest of brown and cream feathers above its eyes.
Pidgey has an extremely sharp sense of direction and homing instincts. It can locate its nest even when far removed from familiar surroundings. It is a docile Pokémon, and generally prefers to flee from its enemies rather than fight them. By flapping its wings rapidly, it can whip up dust clouds and create whirlwinds to protect itself and flush out potential prey. Pidgey is very common throughout its range and can often be seen in meadows and forests.
Pidgey shares its category with Spearow and Natu. They are all known as the Tiny Bird Pokémon, though Natu has also been called a Little Bird Pokémon.
Pidgey is the only Pokémon with a base stat total of 251.
Pidgey is the first Normal/Flying bird-like Pokémon, along with its evolutions, and Spearow and Fearow. This is repeated in later generations with Hoothoot's, Taillow's, Starly's, and Pidove's evolutions and with Fletchling; the latter is the only Normal/Flying bird-like Pokémon in its family—its evolutions are Fire/Flying.
Pidgey has the shortest cry of any Pokémon, being only 0.181 of a second long.
Anatomically, Pidgey resembles a finch or sparrow more than it does a pigeon. However, there have been some references to Pidgey Mail, alluding to homing pigeons. Its category, "tiny bird," added to the sound of the end of its name, could suggest that Pidgey is also based on a chickadee. However, it and its evolutions seem to have more traits related to ospreys than pigeons or chickadees.
