Abstract:
A squirrel-proof selective bird feeder includes a metallic hopper having integral side walls and a back wall defining an open front face, an open top, and a feed portal, a translucent window fastened in water-resistant sealing engagement to the open front face, a top having a sandwiched metallic plate slidably mounted in and frictionally retained by the confronting walls of the open top of the hopper, and a spring-loaded perch having an adjustable tension pivotally mounted to the bottom of the hopper and adjacent the feed portal. In the case of a light bird alighting on the perch having a weight less than that needed to overcome the spring force, the perch remains in at least a partially open state allowing access to the feed portal. In the case of a squirrel or heavy bird having a weight that overcomes the spring force, the perch pivots to a closed state that prevents access to the feed portal. An adjustable feed baffle is provided inside the hopper for regulating the flow of feed into the feed portal, and for providing a preselected opening size selected to accommodate any one of plural feed types.
