Animal feeder

1. A feed reservoir for use with an animal feeder, the animal feeder including a feed dispensing assembly, the feed reservoir comprising:

a flexible bag for holding a feed material, the flexible bag configured to couple to the feed dispensing assembly to provide a continuous supply of the feed material to the feed dispensing assembly;

wherein air is substantially inhibited from entering the flexible bag when the flexible bag is coupled to the feed dispensing assembly.

2. The feed reservoir of claim 1 , wherein the flexible bag is imbued with a foul tasting agent.

3. The feed reservoir of claim 1 , wherein the flexible bag is detachably coupled to the feed dispensing assembly.

4. The feed reservoir of claim 3 , wherein the flexible bag is disposable.

5. The feed reservoir of claim 3 , wherein the flexible bag is reusable.

6. The feed reservoir of claim 1 , wherein the flexible bag extends substantially vertically from an upper portion to a lower portion, and wherein the feed dispensing assembly is configured to couple to the lower portion.

7. The feeder reservoir of claim 6 , wherein the animal feeder includes a connector to support the animal feeder from a support structure, and wherein the connector is configured to couple to the upper portion of the flexible bag.

8. An animal feeder comprising:

a feed reservoir having a flexible bag for holding a feed material; and

a feed dispensing assembly detachably coupled to the feed reservoir, the feed dispensing assembly including a valve to allow animals selective access to the feed material, wherein at least a portion of the feed dispensing assembly is imbued with a foul tasting additive.

9. The animal feeder of claim 8 , wherein the valve is a duckbill valve including at least two lip members, and wherein, when the feed material is not being accessed, the at least two lip members are compressed against one another to inhibit feed leakage.

10. The animal feeder of claim 8 , wherein the feed dispensing assembly includes a perch positioned adjacent the valve.

11. The animal feeder of claim 8 , wherein the feed reservoir includes a plurality of check valve assemblies to allow selective access to the feed material.

12. The animal feeder of claim 8 , wherein the feed reservoir extends substantially vertically from an upper portion to a lower portion, and wherein the feed dispensing assembly is coupled to the lower portion.

13. An animal feeder comprising:

a feed reservoir defining a cavity therein, the feed reservoir having a first end defining an access recess and a second end opposite the first end;

liquid feed material at least partially contained within the cavity to define a feed material fluid level;

a cap removably couplable to the first end of the feed reservoir to selectively seal the access recess; and

a feed dispensing assembly coupled to the second end of the feed reservoir, the feed dispensing assembly including a check valve positioned below the feed material fluid level to allow selective access to the cavity, the check valve inhibiting air from entering the cavity unless placed in an activated position, and wherein the check valve may be placed in an activated position by a bird.

14. An animal feeder comprising:

a feed reservoir defining a cavity;

liquid feed material at least partially contained within the cavity to define a feed material fluid level; and

a check valve in fluid communication with the cavity and positioned below the feed material fluid level, wherein the check valve is a duckbill valve including at least two lip members, and wherein, when the feed material is not being accessed, the at least two lip members are compressed against one another to inhibit air from entering the cavity.

15. The animal feeder of claim 14 , wherein the two lip members are compressed against one another at least partially by fluid pressure provided by the liquid feed material.

16. The animal feeder of claim 14 , wherein the check valve includes an opening, and wherein the opening faces away from the ground.
