Abstract

An adjustable bird feeder designed to regulate access to food based on the beak length and feeding behavior of different bird species. The feeder includes at least one food cage positioned within a frame and at least one movable face located adjacent to the food cage. A user-operated adjustment mechanism, comprising a threaded rod and control knob, moves the face toward or away from the food cage. In the spring-assisted configuration, compression springs provide controlled face retraction. In the single-cage configuration, the face is adjusted without springs, utilizing guide rails for stability. The feeder's design allows the food cage to be aligned or offset with the front grill to adjust the aperture size. Integrated crumb collection trays and aluminum fittings provide structural protection and durability. The feeder accommodates various food types, including suet, seeds, and nuts, by modifying the cage design. The configuration deters squirrels through controlled spatial access.

Dependent claims

An adjustable bird feeder comprising:

a housing having a front face grill, a rear wall, two side walls, a base and an upper opening, the housing defining a fixed distance between the front face grill and the rear wall;
a food cage contained within the housing, the food cage comprising a front cage grill, a rear wall, two side walls, a base and an upper opening configured to provide insertion of bird food, the food cage further configured to hold bird food and move within the housing;
a rail system disposed within the housing and configured to guide the movement of the food cage toward and away from the front face grill;
and
an adjustment mechanism configured to move the food cage along the rail system toward and away from the front face grill to regulate access to the bird food within the food cage based on beak length;
wherein the adjustment mechanism is without springs.

3 more elements

An adjustable bird feeder comprising:

a housing having an upper frame support, a lower frame support, and four corner frame supports, the housing further defining a first face side and a second face side;
a pair of slots formed by and within boundaries of the upper frame support, the lower frame support, and four corner frame supports, and extending perpendicular to a vertical axis of the first face side and the second face side;
at least two food cages configured to hold bird food, the at least two food cages are positioned one above the other in a stacked configuration, each food cage of the at least two food cages slidable in and out of the pair of slots, perpendicular to the vertical axis of the first face side and the second face side, to enable easy loading and replacement of bird food;
two movable faces, one movable face of the two movable faces is attached to the housing on the first face side and one movable face of the two movables faces is attached to the housing on the second face side, adjacent the at least two food cages;
a first set of compression springs supported on the upper frame support of the housing and a second set of compression springs supported on the lower frame support of the housing to support controlled movement of the two movable faces;
and
an adjustment mechanism configured to move the two movable faces toward and away from the at least two food cages;
wherein the adjustment mechanism comprises at least one of:
a threaded rod and knob assembly, an electronically-operated mechanism, a motor-driven mechanism, and a pneumatic or hydraulic actuator;
wherein alignment of the at least two food cages with the two movable faces are adjusted to control the size of openings of the feeder and regulate access to bird food within the at least two food cages based on beak length.
