Lettuce Nutritional Info: Is It Good For Cockatiels?

Lettuce is a leafy green vegetable that is low in calories and high in vitamins A and C and dietary fiber. 

It is also a good source of water for birds, which is important for maintaining proper hydration. 

Cockatiels that receive adequate amounts of lettuce in their diet may benefit from its positive impact on bone strength and reduced inflammatory reactions.

Let’s understand the nutrient composition of lettuce first.

Nutritional Info

The nutritional information for 100 grams of iceberg lettuce typically includes the following:

  • Calories: 5
  • Protein: 0.5 grams
  • Fat: 0.1 grams
  • Carbohydrates: 1.1 grams
  • Fiber: 0.5 grams
  • Vitamin A: 29% of the RDV
  • Vitamin C: 2% of the RDV
  • Calcium: 1% of the RDV
  • Iron: 1% of the RDV


Vitamin A: Vitamin A is essential for maintaining good vision and a healthy immune system in cockatiels.

It also helps develop and maintain the skin, feathers, and mucous membranes. 

Vitamin C: Vitamin C is an important antioxidant that helps to protect cockatiels from the damaging effects of free radicals.

It also helps to maintain a healthy immune system, aids in the production of collagen, and promotes wound healing. 


Calcium: It aids in developing and maintaining strong bones in cockatiels. It also affects muscle function, blood clotting, and nerve function.

A calcium deficiency can lead to problems such as weak bones, muscle spasms, and in serious cases, egg binding in hens.

Iron: Iron is an essential mineral for producing red blood cells, which carry oxygen to all the cells in a cockatiel’s body. It also plays a role in the immune system and brain function.

An iron deficiency can lead to problems such as anemia, which can cause fatigue and weakness.

Other Nutrients 

Lettuce is high in chlorophyll, a green pigment beneficial for cockatiels. 

Chlorophyll helps to detoxify the liver, cleanses the blood, and helps to maintain healthy skin and feathers.

It also contains a small amount of folic acid, which is important for the growth and development of cells in cockatiels. 

Folic acid also helps in the production of red blood cells and the metabolism of amino acids.

Lettuce contains a lot of vitamins, minerals and is a great source of hydration as well.

How Should Lettuce Be Given To Cockatiels?

When giving lettuce to cockatiels, it is important to follow these guidelines:

  • Freshness: Ensure the lettuce is fresh and free of any spoiled or wilted leaves before offering it to your cockatiel. 
  • Preparation: Lettuce should be washed thoroughly and dried to remove pesticides or dirt before offering it to your cockatiel. You can chop it into small pieces or give it a small leaf.
  • Variety: Lettuce should be offered as part of a varied daily diet that includes a variety of fresh fruits, fresh vegetables, seeds, and a quality pellet diet to ensure your cockatiel is getting all the necessary nutrients.
  • Moderation: Lettuce should be offered in moderation, as it is low in protein and fat and high in water. A small amount of lettuce is generally sufficient once or twice a week.

How Much (And How Often) Should You Give Lettuce To Your Bird?

Offer 2-3 small pieces of leaves once a day, maybe 2-3 times a week, depending on the size of your bird.

It is best to avoid lettuce for obese birds because it is a high-calorie food. It may cause them to may develop health issues due to overeating. 

Overall, it is best to stick with small portions of this vegetable when supplementing a healthy diet for your pet cockatiel.

Are There Any Dangers To Giving Lettuce to Cockatiels? Which Type of Lettuce Is Best?

Cockatiels have a notoriously sensitive digestive system. While lettuce is a safe option, it is best to offer it in small amounts. 

Here are a few reasons why:

Miner’s lettuce contains high amounts of calcium oxalates, an antinutrient compound that limits the amount of minerals birds can absorb. 

Lettuce also contains substantial amounts of fresh water, which can result in excessive hydration if your bird eats too much of it. 

This can lead to watery droppings and diarrhea. 

Darker varieties of lettuce are best for cockatiels

The best option for feeding your cockatiel-safe lettuce would be dark green leaf lettuces such as romaine which have lower oxalate levels.
