Implementations described and claimed herein provide apparatuses and methods for facilitating filling and cleaning of bird feeders that are aesthetically pleasing and adaptable for attracting different types of birds. In one implementation, a bird feeder includes a port having a surface extending from a proximal end to a distal end. The proximal end has a connecting portion configured to connect to a reservoir. The surface has one or more openings defined therein. A small seed converter is insertable into the port, and the small seed converter includes a plurality of teeth extending from an edge. The plurality of teeth are configured to narrow the one or more openings for dispensing small sized seed.

A top-fill hummingbird feeder is provided having a nectar container with a liquid flow opening at a lower end and a removable cap at an upper end, a feeding basin positioned below the nectar container, and a sealing mechanism associated with the liquid flow opening and the feeding basin. The sealing mechanism includes a bottle seal assembly configured for removable coupling with a base of the feeding basin, and a float valve captured by said bottle seal assembly to prevent rotation thereof while allowing the float valve to move upwardly and downwardly with changing nectar levels in the feeding basin. The float valve includes a float having a frame with a buoyant member mounted thereon, the buoyant member being made of a closed-cell foam.

A hummingbird feeder is provided that has a nectar container with a lower end liquid flow opening, a nectar basin positioned below the nectar container and removably coupled thereto, and a recessed elastomeric sealing member. The nectar basin includes an upper part and a lower part that are separable from one another and configured to be engaged along adjacent surfaces thereof. The recessed elastomeric sealing member is held against a retaining structure and is positioned to be engaged between the upper and lower parts of the nectar basin to create a liquid tight seal of the nectar basin when the feeder components are assembled.

An Oriole bird feeder having a nectar reservoir with a base and a tapered port, and preferably a tapered port/perch assembly, is provided. The bird feeder allows Orioles and other similarly sized members of the Icterid family of birds to land on the perch and access the nectar in the reservoir base while, due to the diminishing taper of the opening in the tapered port, simultaneously preventing average sized Italian, Carniolan and Caucasian honey bees from entering the reservoir base through the port to obtain the nectar where they subsequently become trapped and perish.

Implementations described and claimed herein provide apparatuses and methods for facilitating filling and cleaning of bird feeders that are aesthetically pleasing and adaptable for attracting different types of birds. In one implementation, a bird feeder includes a proximal edge extending around a central line and defining a plane. An outer surface and an inner surface each extends distally from the plane. The inner surface is connected to the outer surface by the proximal edge. An opening is formed by the proximal edge and positioned on the plane. A hanger is disposed distal to and not intersecting the plane, and the hanger assembly has a hanging portion positioned on the central line.

A top-fill hummingbird feeder is provided having a liquid container with a liquid flow opening at a lower end and a removable cap at an upper end, a feeding basin positioned below the liquid container, and a sealing mechanism associated with the liquid flow opening and the feeding basin. The sealing mechanism includes a bottle seal assembly configured for removable coupling with a base of the feeding basin, and a float valve captured by said bottle seal assembly to prevent rotation thereof while allowing the float valve to move upwardly and downwardly with changing nectar levels in the feeding basin. The feeding basin is filled by gravity feed of the liquid in the container through the liquid flow opening when the sealing mechanism is open. When the feeding basin reaches a full position, the liquid nectar raises the float valve which, in turn, acts to close the liquid flow opening.
