Abstract: A seed port, specifically designed to permit dispensing large and small seeds from the same feeder, can be used with a bird feeder having a reservoir for the containment of bird seed, wherein the seed port has a platform with an opening that attaches to the reservoir and aligns with an opening in the reservoir. The seed port further provides a hinged trough that pivots within the opening of the seed port to alternatively offer a variety of seed sizes in the bowl of the trough or to permit access to only smaller seeds in the reservoir through an appropriately sized slot in the trough that becomes apparent only when the trough is pivoted to deny access to the bowl.

Abstract: A seed port offering the option of selectively dispensing only small seeds from a reservoir-type bird feeder, comprises a carriage supporting a framing flange corresponding to the opening in the reservoir, a removable baffle to limit the flow of seeds from the reservoir, and a disk member that is optionally inserted within the framing flange, in the absence of the baffle, to selectively limit access to only smaller seeds through a defined opening in the disk.

Abstract: A seed port, intended to permit dispensing large and small seeds from the same feeder, can be used with a bird feeder having a columnar reservoir for the containment of bird seed wherein the seed port has a platform with an opening that attaches to the reservoir in alignment with an opening in the reservoir. The seed port further provides a trough and a hinged lid with a small opening that will alternatively deny access to the trough while permitting access to seeds in the reservoir; or deny access to seeds in the reservoir while permitting access to seeds in the trough.
