The term 'Pigeon Perch' refers to a structure that provides a place for pigeons to rest and nest. It is typically composed of a LEDGE, ROOST, STOOL, and STATUE. A LEDGE is a flat, horizontal surface that protrudes from a wall or other structure. A ROOST is a place where birds rest and sleep. A STOOL is a short, three-legged stand used as a seat. Finally, a STATUE is a carved or cast figure of a person or animal. Together, these components create a comfortable and safe environment for pigeons to perch.
