Claim:
A bird-operated interactive bird feeder comprising: a housing that stores bird feed, wherein the housing comprises a bottom, and wherein the bottom includes an aperture; and a tool comprising two co-linear portions, wherein at least a portion of the tool is positioned within the housing and in the vicinity of the aperture, wherein the tool is movable from a first position to a second position via rolling motion of the two co-linear portions along the bottom, and wherein the tool is capable of moving from the first position to the second position when a bird exerts a force on the tool; wherein the at least a portion of the tool bridges the feed thereby restricting the bird feed from passing through the aperture when the tool is in the first position, and wherein the at least a portion of the tool disrupts the bridged feed thereby allowing the bird feed to pass through the aperture when the tool is in the second position.
