US Patent 7093562 Bird feeder and kit

A hummingbird feeder and kit including a solution reservoir, a feeding assembly, and a coupler for unreleasably coupling said feeding assembly to said solution reservoir. The reservoir includes either a dissolvable solid or a premixed feed solution. The unreleasable coupling between the reservoir and the feeding assembly prevents the subsequent re-use of the hummingbird feeders, minimizing the user's contact with bacteria-infested feeding solution and the spread of disease among birds.
