PROBLEM TO BE SOLVED: To provide a device for preventing flying birds from coming, not allowing the birds such as pigeons to pile twigs and weeds, and land, having no space for intrusion and not showing an appearance for harming birds. SOLUTION: This preventing device for come flying birds by installing a plurality of interrupting pieces 2 as standing in a prescribed interval on a base plate is provided by forming the above interrupting pieces 2 as widening the width of the parts as going lower by providing projecting parts 4a to 4d in many steps, of which upper surfaces are tilted in lower direction, in up and down rows, enlarging the projection height of lower positioned projecting parts higher than that of the higher positioned projecting parts, and installing projections 5a to 5c among the above projecting parts, and between the projecting parts and the base plate 3. Thereby, since materials for making nests such as twigs and weeds slide down on the upper surface of the above projected parts and do not pile up, there is no space for invasion into the above device such as between the projecting parts, and also it is very hard for birds to perch on it because of the particular shape of the interrupting pieces 2, it can surly prevent come flying birds.
