Can Cockatiels Eat Tomatoes?

Navigating the dietary needs of your feathered friend can be a daunting task, especially when it comes to sharing our favorite foods with them. One common question that many bird enthusiasts grapple with is about tomatoes. Can cockatiels safely enjoy this juicy fruit?

As a general rule, cockatiels can consume ripe tomatoes in moderation. However, it’s essential to be cautious of the green parts, such as stems and leaves, which contain solanine, a toxic compound for these birds.

Dive deeper into this guide to understand the nuances of feeding tomatoes to cockatiels, ensuring their health and happiness.

How Many Tomatoes Can Cockatiels Eat?

When it comes to feeding tomatoes to your cockatiel, moderation is key. Based on my observations and research, I recommend an intake of 9-12 grams of tomatoes for your cockatiel. This might seem like a small amount, but remember, cockatiels have a tiny stomach.

It’s essential to ensure that tomatoes, along with other fruits and vegetables, only make up about 30% of their diet. The majority of their meal, around 60%, should consist of pellets. These pellets are specially formulated to provide all the essential nutrients your cockatiel needs. The remaining 10% can be treats like seeds, nuts, and other fruits. This balance ensures that your cockatiel gets a varied and nutritious diet, promoting their overall health and well-being.

Are Tomatoes Good For Cockatiels?

Before we delve into the specifics, let’s address a common misconception. Many people believe that if a food is safe for humans, it’s safe for birds. However, that’s not always the case. Now, let’s explore the relationship between cockatiels and tomatoes.

Health Benefits Of Tomatoes For Cockatiels

On the brighter side, tomatoes are packed with nutrients beneficial for cockatiels:

  • Antioxidants: Tomatoes are rich in lycopene, lutein, and zeaxanthin. These antioxidants not only protect against heart disease but also enhance the vividness of your cockatiel’s feathers. For male cockatiels, this is especially beneficial as vibrant feathers increase their chances of attracting a mate.
  • Vitamin C: Tomatoes are a good source of vitamin C, which is vital for various functions like boosting the immune system, healing wounds, and preventing kidney problems. Since cockatiels can’t produce vitamin C naturally, incorporating it into their diet is essential.
  • Potassium: This mineral helps maintain fluid balance in cells and tissues, ensuring strong bones and a well-functioning digestive system. It also plays a role in regulating a cockatiel’s blood pressure.
  • Folate: Folate aids in protein metabolism. A deficiency can lead to anemia, a weakened immune system, and under-development of the reproductive tract in cockatiels.
  • Vitamin K: Essential for bone health and eggshell quality, vitamin K also ensures timely blood clotting. A deficiency can lead to internal hemorrhages and increased mortality in cockatiels.

Risks Associated With Feeding Tomatoes To Cockatiels

While tomatoes offer a plethora of benefits, it’s essential to be aware of the potential risks they pose to cockatiels. Let’s delve into some of the concerns that arise when considering tomatoes as part of their diet.

1. Acidity And Citric Acid Content

Tomatoes are naturally acidic. While this might not be a problem for us, for cockatiels, it’s a different story. The high acidity in tomatoes, especially the citric acid, can bind to iron in their body. This can lead to diseases that manifest symptoms like a swollen stomach, difficulty breathing, and in severe cases, paralysis. Furthermore, excessive consumption can lead to stomach ulcers in cockatiels. So, while it’s okay to treat your bird to a tomato slice once in a while, it’s crucial to monitor the quantity and frequency.

2. Solanine: A Toxic Element

Solanine is a toxic alkaloid found in the green parts of tomatoes, including unripe tomatoes, leaves, stems, and seeds. This compound can be harmful to cockatiels. It’s crucial to ensure that you never feed your bird the green parts of a tomato. The dangers of solanine include digestive issues, respiratory problems, and in severe cases, it can be fatal.

3. Other Risks

Overfeeding tomatoes can lead to digestive problems and an imbalance in their diet. Additionally, cockatiels might develop a preference for the sour taste of tomatoes, making it a habit-forming fruit. This can deter them from consuming other essential foods, leading to nutritional deficiencies.

Specific Types Of Tomatoes And Their Suitability

Now that we’ve covered the risks, let’s explore the different types of tomatoes and how they fit into a cockatiel’s diet.

1. Raw Tomatoes

Raw tomatoes, especially the ripe ones, are generally safe for cockatiels. However, due to their acidity levels, they should be given in moderation. From my experience, cockatiels often show a preference for ripe tomatoes over the unripe ones, likely due to their sweeter taste.

2. Cherry Tomatoes

Cherry tomatoes, with their convenient size and sweeter taste, can be a delightful treat for your cockatiel. However, they share the same acidity concerns as larger tomatoes. If you decide to feed cherry tomatoes, ensure they are ripe and given in moderation.

3. Canned Tomatoes

I’d advise against feeding canned tomatoes to cockatiels. Canned tomatoes often contain added acids, which can be harmful. Additionally, there’s a risk of food poisoning bacteria present in canned foods, which can be detrimental to your bird’s health.

4. Green Tomatoes

Green or unripe tomatoes have higher acidity levels compared to ripe ones. As mentioned earlier, they also contain solanine. Given these concerns, it’s best to limit or avoid feeding green tomatoes to your cockatiel altogether.

Preparing Tomatoes For Cockatiels

So, you’ve decided to introduce tomatoes into your cockatiel’s diet. That’s great! But before you do, it’s essential to prepare them correctly to ensure your feathered friend’s safety and health.

1. Choosing The Right Tomato

When selecting tomatoes for your cockatiel, always opt for ripe, red ones. These are less acidic and safer for your bird. On the other hand, green, unripe tomatoes contain solanine, a toxic compound that can be harmful to cockatiels. So, it’s best to steer clear of them.

2. Preparing The Tomato

Once you’ve chosen the right tomato, the next step is preparation. To reduce the acidity, you can dry the tomato slices for a few hours before offering them to your bird. As for the serving size, a small slice or two is sufficient. Remember, it’s always better to start with a smaller portion and observe how your cockatiel reacts.

3. What To Avoid

While tomatoes can be a nutritious treat, there are certain parts you should avoid:

  • Tomato seeds: They can be hard for cockatiels to digest.
  • Stems and leaves: These contain solanine, which, as mentioned earlier, is toxic to cockatiels.

Additionally, be mindful of the quantity. Overfeeding can lead to digestive issues. It’s also essential to monitor the frequency to ensure your cockatiel doesn’t develop a habit of only wanting tomatoes and neglecting other vital foods.


Feeding tomatoes to your cockatiel can be a delightful treat for them, provided it’s done right. By understanding the benefits and risks, and preparing the tomatoes correctly, you can ensure a safe and nutritious addition to their diet. Remember, variety is the spice of life, and the same goes for your cockatiel’s diet. Introduce different foods, monitor their reactions, and always prioritize their health and well-being.
