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.

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.
