摘要：
A top-fill hummingbird feeder has a liquid container with 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.
