A bird feeder device comprising:
- a reservoir having a top end and a lower end with an opening and a side wall between said top end and said lower end, said side wall near said lower end having exterior threads, said lower end opening being at least as large as other interior portions of said reservoir, including the interior portion at the top end,
- a bowl assembly having an upper open end with interior threads adapted to matingly engage said threads on said side wall of said reservoir such that said bowl assembly may be removably coupled to said lower end of said reservoir,
- said reservoir and said bowl assembly when coupled together being adapted to hold a liquid suitable for feeding birds,
- said bowl assembly having an upper wall which extends outwardly from the side wall of said reservoir when said bowl assembly is coupled to the lower end of said reservoir,
- said upper wall of said bowl assembly comprising a port for allowing a bird to feed on the liquid in said assembly by way of said port,
- support means coupled to said top end of said reservoir to which a suspending means may be coupled for suspending said bird feeder device,
- a wall means integral to the top end of said reservoir and surrounding said support means for holding a liquid substance suitable for preventing the passage of ants or the like from the suspending means to the bird feeder device outside of said wall means.
