发明名称 Weight responsive spray bird-scare perch
摘要 A bird scare perch is disclosed. The bird scare perch is comprised of an elongated member which forms a perch upon which birds can land. A plurality of spray nozzles are supported adjacent to and directed at the elongated member. A source of fluid, preferably a liquid, communicates with the spray nozzles. A control mechanism, actuated by birds landing upon the elongated member, activates the flow of the fluid out of the spray nozzles. In this manner, the birds which have landed upon the elongated member are sprayed and placed in distress.
