Abstract: A top-fill hummingbird feeder has a liquid container with a a lower bottom opening which can be screw-threaded into a central collar of a feeding basin. An insert is received within the central collar and is configured to be vertically movable between a first position in which fluid is allowed to flow from the liquid container to the basin, and a second position in which fluid flow from the container to the basin is prevented. Movement of the insert between the two positions is effected by pushing the liquid container toward the basin (the closed position) and by pulling the liquid container away from the basin (the open position). Each movement of the insert has an associated “snap” or gives positive physical feedback which the user can feel that assures the user that the desired fluid flow or fluid sealed position has been achieved.
