Why Is My Cockatiel Eating So Much?- How Much Is Too Much?

Why Is My Cockatiel Eating So Much

If you have owned a cockatiel for some time now, you can estimate how much it eats daily. So if the cockatiel suddenly starts eating more than usual, you may wonder what might be the cause. Most cockatiel owners will be excited that their bird has a high appetite and may even provide it with more food. However, is it a good thing?

Why is my cockatiel eating so much? When they are hormonal and bored, cockatiels will eat a lot. If there is nothing else to do in the cage, the cockatiels will focus entirely on the food bowl. Furthermore, if the diet is poorly balanced, the cockatiel will become malnourished, which may cause it to overeat to compensate for the malnutrition.

Overeating is a serious issue that can make your cockatiel develop serious health issues like obesity. This article will discuss everything about why your cockatiel is eating so much.

Why Is My Cockatiel Eating So Much

Cockatiels may eat a lot due to several reasons. They include;

Lack of mental stimulation

Cockatiels are very social birds and need entertainment in their daily lives. If you give them no attention, cockatiels will start overeating just to keep themselves busy. To prevent this, you can encourage foraging. In the wild, cockatiels will forage for their food which is more entertaining than consistently eating from a food bowl.

Poor nutrition

If the cockatiel is malnourished, it tends to overeat. A one-food diet can cause the cockatiel to miss certain nutrients from its diet. For example, if you serve an all seed-diet every day. Seeds are high in carbohydrates but miss out on other essential nutrients. 

In addition, cockatiels digest their food very fast due to their high body metabolism. So if the cockatiel feels like its body is not getting enough nutrients, it will continue eating to find the missing nutrients. A balanced diet is the most common way to prevent overeating.

Also, if the cockatiel has a digestive tract issue, it can suffer from malabsorption. This is where the stomach does not fully absorb food into the body. The cockatiel will then overeat to receive enough vitamins and minerals.

Hormonal issues

This is especially common during breeding seasons which are in the spring months. The cockatiel’s body requires more minerals and vitamins in preparation for nesting. Female cockatiels use a lot of calcium when laying eggs, so they might overeat to replenish the lost calcium.

If a cockatiel overeats, it might become obese, leading to health issues. It is critical to supply your cockatiel with a well-formulated diet and occasional fruit for them to maintain a healthy weight.


When a cockatiel has parasites, it eats a lot. Parasites tend to leach nutrients from the cockatiel’s system, leading it to overeat to replenish lost nutrients.

How Much Does a Cockatiel Eat a Day?

You should feed cockatiels a quarter cup of pellets per day for baby cockatiels and a half cup for adult cockatiels. A half cup of pellets contains 30 to 40 grams of pellets.

The smaller the portion of fruits and vegetables, the better. If your bird eats so many fruits and veggies that it misses its primary meal, it could become malnourished and even obese. 

Provide a half to one teaspoon of fruit to a baby bird and a tablespoon of fruit to an adult cockatiel. Offer half a teaspoon of vegetables and a half tablespoon of a protein source to baby cockatiels for vegetables.

Serve a small spoonful of vegetables and one and a half teaspoons of protein to your adult cockatiel. You should only serve fruits and vegetables twice or three times per week. This prevents the cockatiel from becoming attached to them.

Common protein sources include boiled or scrambled eggs, whole grain bread, and sprouted legumes. Protein should make up only 8% of the cockatiel’s diet.

Here are a few ways you can prevent your cockatiel from overheating.

  • Add puzzles, toys, and another cockatiel to the cage. That way, your cockatiels will not be bored or lonely. That will divert their attention from bad eating habits. You can also spend time with the cockatiel to ensure it does not overeat due to lack of attention.
  • Encourage foraging. Foraging makes the cockatiels burn calories while looking for food. You can hang the food from the perches or place it between cage bars. You can also fill a food bowl with clean pebbles and scatter seeds in between the stones, so the cockatiel has to search for food.
