Can my brother eat oranges?

Brother 子 cannot eat oranges. Its gastrointestinal function is relatively weak and cannot eat acidic and moisture fruit.It itself is a poultry of the brothers of the Sanbird. Most of the whole body is black. There are orange drooping meat on both sides of the head.It is good at calling, and the call is very clear. It also has the ability to imitate. It usually becomes a pair of activities. Sometimes it is also in groups. I like to eat wild fruits, but I can also eat insects.
