Squirrel guard for a bird feeder |
摘要 |
A squirrel guard for use with a bird feeder which stores and dispenses bird seed. The feeder comprises an upstanding housing and a support for positioning the feeder in an elevated position. The squirrel guard comprises a generally round and planar tray mounted beneath the feeder. The tray acts to deny squirrel access to the bird seeds and also as a collection tray for spilled bird seed. A tilt connector is arranged beneath the lower side for supporting the tray in a generally horizontal position when carrying only a minimal weight such as bird seed and small birds. The connector is such that the tray tilts to a generally diagonal position when engaged with a relatively heavy weight such as a squirrel. When engaged by a squirrel the tray moves to the tilted position causing the squirrel to fall from the tray. |
