What not to feed cockatiels

In the following list, we’ll delve into the essential dos and don’ts of a cockatiel’s diet, spotlighting potentially harmful foods that should be strictly off their menu. This can help you avoid unintentional mistakes and ensure your pet bird enjoys a healthy and fulfilling life.

An avocado could be dangerous for cockatiels, so you should never feed it to them. A chemical in avocados called persin is harmful to birds and other animals. When cockatiels eat avocado, it can cause major health problems like heart, breathing, and even death.

This is why it’s important to keep cockatiels away from any part of an avocado, including the fruit, the seeds, and the skin.

2. Chocolate

Chocolate is harmful to birds and shouldn’t be given to cockatiels. Theobromine, which is in chocolate, can hurt their sensitive systems. If a cockatiel eats chocolate, it can cause several health problems, such as stomach problems, a faster heart rate, tremors, and even death.

To ensure cockatiels stay healthy and avoid needless health risks, it’s best not to give them any chocolate.

3. Mushrooms

Because mushrooms can be dangerous, they’re among the foods you shouldn’t give your pet. Some kinds of mushrooms are deadly to these species and can make them sick, hurt their livers, or even kill them. It’s hard to know which mushrooms are safe to eat, so it’s best to stay cautious and keep mushrooms out of a cockatiel’s diet to keep them healthy and happy.

4. Onion and garlic
