I believe most people already know that birds are absolutely not allowed to eat onions and garlic. But why? Take a look.
我相信大多數人知道雀鳥是絕對不能吃洋蔥和大蒜/蒜頭。 但是，為什麼呢？ 看看以下貼文。
Celery is a vegetable that birds can eat. Celery contains rich nutrients such as vitamins A, C, and K. Although celery is safe for birds, celery stringy part (fiber) are unsafe to birds. If birds eat the stringy part, it can cause crop impaction or constipation, so you must remove the celery stringy part before feeding birds. Meantime, keep in mind that vegetables must be thoroughly washed before giving to birds.
