The present invention provides a bird feeder quantitative feeding device for accommodating a bird, and the bird feeding device comprises a cage, a first gate, a second gate and an actuating member, and the cage The utility model has an open mesh shape, and a feeding container is built in the cage to provide bird and bird foraging. The first gate and the second gate respectively pivot the two sides of the cage, and the movable cover covers the opening of the cage, and the movable member pivots. The first gate is arranged between the first gate and the cage body, and the actuating member has a fixed moving rod and a supporting rod. The supporting rod can movably support the first gate, and the actuating rod provides the bird's gravity pedaling, thereby driving the supporting rod to pivot and disengage from the first A gate enables the first gate to open and close the opening of the cage, thereby effectively controlling the food consumption of each bird and solving the problem of uneven feeding of some birds.本創作提供一種鳥禽定量各別餵食裝置，其用於容納餵食一隻鳥禽，鳥禽定量各別餵食裝置包含一籠體、一第一閘門、一第二閘門及一作動件，籠體為開放網格狀，且籠體內置放有一餵食容器，提供鳥禽覓食，第一閘門及第二閘門分別樞設籠體之兩側，並相對活動蓋合籠體的開口，作動件樞設於第一閘門與籠體間，而作動件具有一致動桿及一支撐桿，支撐桿可活動支撐第一閘門，而致動桿提供鳥禽重力踩踏，進而帶動支撐桿樞轉並脫離第一閘門，使第一閘門可活動開合籠體之開口，藉以有效控管每隻鳥禽的食量，解決部分鳥禽餵食不均的問題。
