Abstract: A hanger hook is of modified S shape and all parts of the hanging hook lie substantially in the same plane. The hook has utility particularly but not exclusively in hanging a birdfeeder from a substantially horizontal tree branch and the like. The hook has a lower open loop providing a bite for receiving thereover the circular portion of a birdfeeder or plant hanger. The hanger also has an upper open loop for receiving the branch. The hook resists efforts of squirrels, raccoons, or the like but not people to disassemble the hanger from the hook and to disassemble the hook from the branch.
