An animal feeder comprises a vertical portion having a front side, a back side, a left side, and a right side. A first groove extends continuously through each of the left side, the front side, and the right side. At least a part of the back side is generally concave to facilitate the securement of the feeder to a tree. An angular portion of the feeder extends from the vertical portion at an angle. The angular portion has a mouth with a stop. The vertical portion and the angular portion collectively define a cavity configured for retaining animal feed. The cavity is accessible at least at the mouth. The back side comprises a channel, a first bracket, and a second bracket, each of which are collectively configured for securement of a T-post.
