Pigeons are small birds found in The Sims 3: Late Night, The Sims 3: Pets, The Sims Medieval, The Sims 4: Get Together, The Sims 4: City Living, and The Sims 4: Cats & Dogs. Pigeons are present in The Sims 2 as a neighborhood decoration, but do not actually appear in-game.
In The Sims 3: Late Night, pigeons are often seen outside the City Hall in Bridgeport, though they do not have a great impact on gameplay, as they cannot be interacted with, and wander around aimlessly.
Pigeons are a common pet in the bird collection in The Sims 3: Pets, although the pigeons outside the Bridgeport City Hall cannot be collected, as they are only considered a special effect by the game.
In The Sims 4: Get Together, The Sims 4: City Living and The Sims 4: Cats & Dogs, pigeons are decorations and are often seen wandering in Windenburg, San Myshuno and Brindleton Bay (where their technology was improved) respectively.
