A liquid birdfeeder includes a generally upstanding container having a large opening at its top end and a bottleneck opening at its lower end. A quarter-turn removable cap is screw-threaded onto the top end to seal the top end opening. The lower bottleneck opening is screw-threaded into a central collar of a feeding basin having a plurality of feeding ports. An actuator rod extends longitudinally through the container and is operatively connected to a biased sealing mechanism which selectively seals or opens the bottleneck opening. When the removable cap is screw-threaded onto the top end opening, the cap depresses the actuator rod causing the biased sealing mechanism to move to an open position which allows liquid to flow out from the container into the feeding basin. When the removable cap is removed, the actuator rod can move upwardly under the force of the biased sealing mechanism, which moves the sealing mechanism to a closed position and prevents liquid in the container from flowing into the feeding basin. The container can then be filled through the top opening without flooding the feeding basin. In one preferred embodiment, the bird feeder includes a common functional feeding module connected within an outer decorative cladding by an interference fit.

What is claimed is: 1. A hummingbird feeder comprising:(a) a reservoir bottle having a top end opening and a bottom end opening;(b) a removable cap for sealing the top end opening;(c) a feeding basin connected to the bottom end opening and having at least one feeding port, said feeding basin configured to be in liquid flow communication with said reservoir bottle when said top end opening is sealed by said cap to dispense liquid nectar for access to hummingbirds through said feeding port;(d) an actuator rod extending through said reservoir bottle and movable between an up position and a down position by sealing and unsealing said cap from said top end opening; and(e) a sealing mechanism operatively connected to the actuator rod to move between a closed position closing said bottom end opening and an open position opening said bottom end opening by unsealing and sealing, respectively, said cap from said top end opening, said sealing mechanism being upwardly biased to said closed position when said cap is unsealed from said top end opening.
