Systems and methods for resisting intrusion by a pest include a reservoir extending between a proximal end and a distal end, and the reservoir defining an interior. A basin is mounted to the reservoir. The basin has a basin body and a basin surface. A sleeve assembly has a sleeve body and a port defined in the sleeve body. A tensioner translationally mounts the sleeve body relative to the basin body. The sleeve body translates distally from an accessible position to an occluded position when a weight applied to the sleeve assembly exceeds a weight threshold set by the tensioner. The accessible position includes bird food on the basin surface being accessible through the port. The occluded position includes the port being disposed distal to the basin surface such that the bird food on the basin surface is inaccessible through the port.
