The present technology provides systems and methods for resisting intrusion ofa pest into asupply of bird seed held in a birdfeeder. In one implementation, a base has asurface extendingto a base edge. A perch has a body extending from a perch first end to a perchsecond end.The perch body is disposed relative to a slot. A collapsible member is mountedto the base at afirst attachment point. The first attachment point is disposed inward relativeto the base edge.The collapsible member is mounted to the perch at a second attachment point.The collapsiblemember has a pivot point defined between the first attachment point and thesecond attachmentpoint. The collapsible member moves the perch from a feeding position to a non-feedingposition by pivoting at the pivot point upon an application of a force above athreshold on theperch body.
