When it comes to nesting, pigeons play by a different set of rules. They don’t just have a "season"—they have a lifestyle that turns the conventional bird calendar on its head.
Pigeons are not arboreal; they do not prefer trees. Their instincts drive them to cliff edges, which in the city translates to ledges, window sills, air conditioning units, bridge supports, and warehouse rafters. They prefer a slight overhang that offers protection from the elements and predators. pigeon nesting season
