Abstract: The present disclosure relates to a filter. The filter includes a porous element, a compression element and a housing. At least a portion of the porous element is coated with an alkylsilyl coating. The compression element is configured to receive the porous element thereby forming an assembly. The housing has an opening formed therein. The opening is configured to receive the assembly. The assembly is retained within the opening when the assembly is received therein.

Abstract: Implementations described and claimed herein provide systems and methods for resisting intrusion by a pest. In one implementation, a reservoir extends between a proximal end and a distal end, and the reservoir defines 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.

Abstract: A perch extension for a bird feeder having an elongated perch body that defines a cavity that is adapted to fit at least partially over a perch on a bird feeder. The perch extension may optionally have a support member that is coupled to the perch body, and is further adapted to fit at least partially around the seed container of the bird feeder. The perch extension may optionally define protuberances to provide a snap-fit or press-fit engagement with the bird feeder perch.

Abstract: Implementations described and claimed herein provide a bird feeder finial assembly. In one implementation, a bird feeder includes a finial having a finial body. The finial has a longitudinal axis. A swivel surface is disposed on the finial body, and a neck extends distally from the finial body along the longitudinal axis. The swivel has a swivel body with a proximal surface and a distal surface. A swivel opening is defined in the swivel body. The neck extends through the swivel opening, and the swivel body is translatable along the neck. A hanger is connected to the swivel body. The swivel body translates along the neck towards the first swivel surface into a swivel position when a suspending force is applied to the hanger, and the finial freely is rotatable about the longitudinal axis independent of the hanger when the swivel body is in the swivel position.

Abstract: Implementations described and claimed herein provide systems and methods for attracting different types of wild birds, as chosen by a user. In one implementation, a top section is configured to engage a cap, and a bottom section positioned opposite the top section includes at least one feeding station. A supporting member extends vertically from the bottom section to the top section. The supporting member, the top section, and the bottom section forma frame. A reversible insert has an elongated body extending between a first edge and a second edge. The first edge has a plurality of ports, and the second edge one or more slots. The frame is adapted to receive the reversible insert in an orientation based on a size of the bird seed.

Abstract: Implementations described and claimed herein provide a system for attracting a desired bird species. In one implementation, a matching panel has a body including a first portion and a second portion. A seed indicator is disposed on the first portion of the body of the matching panel. A visual seed representation of a seed type is included in the seed indicator, and a seed match indicator is displayed in association with the visual seed representation. A bird indicator is disposed on the second portion of the body of the matching panel. A visual bird representation of the desired bird species is included in the bird indicator. A bird match indicator is displayed in association with the visual bird representation. The bird match indicator has a linkage with the seed match indicator.

In one implementation, a reservoir extends between a proximal end and a distal end, and the reservoir defines 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.

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.

Abstract: There are generally two styles of modern bird feeders: the tubular feeder with a tubular reservoir and several perches attached to the tubular reservoir at various positions around the reservoir, and the more traditional rectangular bin style with one or two feeding stations. These bin feeders are constructed to feed only general bird seed of mixed variety and are not selectively configurable to feed a specific small seed like thistle. The disclosed bin feeder includes removable and repositionable bin sidewalls with appropriately shaped upper and lower longitudinal edges to exclusively provide appropriate openings for thistle feed along one of the longitudinal edges or an appropriate opening for generally larger seed along the other of the longitudinal edges.
