Through the combination of the direction indicator and the bird feeder, not only the direction indicator indicates the direction for others, but also birds feed on the bird feeder above the direction indicator, which has strong ornamental, smart and reasonable structure design, and strong practicality. The bird feeder has a rotating function to facilitate cleaning of the outside of the bird feeder. By providing a bird feeding space for storing birdseed in the direction indicator, the direction indicator has the function of a bird feeder, and the space design of the direction indicator is skillfully utilized. ## Claims ### Claim 1 A rotary bird feeder device, comprising a pole body and a bird feeder disposed on a top of the pole body, the bird feeder being horizontally rotatable relative to the pole body; the pole body being provided with a direction indicator, the direction indicator having a bird feeding space therein for storing birdseed, the direction indicator further having a plurality of stations around the bird feeding space for birds to rest thereon. ### Claim 2 (depends on 1) The rotary bird feeder device as claimed in claim 1, wherein the top of the pole body is provided with a connecting post extending upwardly, a bottom of the bird feeder is recessed to form a connecting groove, the connecting post is fitted and positioned in the connecting groove of the bird feeder, and the bird feeder is horizontally rotatable relative to the connection post. ### Claim 3 (depends on 2) The rotary bird feeder device as claimed in claim 2, wherein the connecting post is provided with an upper gasket and a lower gasket for preventing the bird feeder from rotating too fast and falling, the upper gasket and the lower gasket are disposed on upper and lower ends of the connecting post respectively, inner circumferential surfaces of the upper gasket and the lower gasket are in contact with an outer circumferential surface of the connecting post, and outer circumferential surfaces of the upper gasket and the lower gasket are in contact with an inner circumferential surface of the connecting groove. ### Claim 4 (depends on 1) The rotary bird feeder device as claimed in claim 1, further comprising an adjusting and positioning assembly for detachably mounting and positioning the direction indicator to the pole body; the adjusting and positioning assembly including a sleeve and an adjusting screw; the sleeve having a bottom wall, an inner annular wall and an outer annular wall, the inner annular wall and the outer annular wall being connected to the bottom wall, the outer annular wall surrounding the inner annular wall to form a positioning groove between the inner annular wall and the outer annular wall, the positioning groove having an upper opening; the inner annular wall and the outer annular wall being provided with threaded holes extending horizontally; the bottom wall being provided with a hole extending vertically, the inner annular wall surrounding the hole; the direction indicator being connected with a positioning portion extending vertically; the pole body passing through the hole of the bottom wall of the sleeve, the adjusting screw passing through the threaded holes of the outer annular wall and the inner annular wall in sequence, an inner end of the adjusting screw abutting against the pole body, a nut being fitted on the adjusting screw, the nut being pressed against an outside of the outer annular wall, the positioning portion being inserted from the upper opening into the positioning groove. ### Claim 5 (depends on 1) The rotary bird feeder device as claimed in claim 1, wherein the direction indicator includes four direction indicators defined as east, south, west, and north direction indicators respectively, English words of the east, south, west, and north direction indicators are abbreviated as E, S, W, and N; each of the direction indicators has two identification plates disposed oppositely, a plurality of connecting strips are connected between the two identification plates to form the bird feeding space, and the bird feeding space has an upper end opening. ### Claim 6 (depends on 5) The rotary bird feeder device as claimed in claim 5, wherein the direction indicator is located below the bird feeder, and the bird feeding spaces of the four direction indicators form a surrounding arrangement relationship with the bird feeder. ### Claim 7 (depends on 1) The rotary bird feeder device as claimed in claim 1, wherein an outside of the bird feeder is provided with an arrow. ### Claim 8 (depends on 1) The rotary bird feeder device as claimed in claim 1, wherein the pole body includes an upper pole, a middle pole and a lower pole that are detachably assembled in sequence; the direction indicator is disposed on the upper pole, and a lower end of the lower pole is provided with a peg. ### Claim 9 (depends on 8) The rotary bird feeder device as claimed in claim 8, wherein the middle pole, the upper pole and the lower pole are detachably connected to each other through internal threads and external threads. ### Claim 10 (depends on 8) The rotary bird feeder device as claimed in claim 8, wherein the middle pole, the upper pole and the lower pole are detachably connected to each other through buckle holes and buckle members. ### Claim 11 (depends on 1) The rotary bird feeder device as claimed in claim 1, wherein the pole body is provided with a decorative member, and the decorative member is located below the direction indicator.
