Cockatiels are intelligent, sociable birds with big personalities. To keep them healthy and active, a balanced, nutritious diet is essential. Whether you’re a new bird owner or just looking to improve your cockatiel’s feeding routine, here’s what you need to know.


The Basics of a Healthy Cockatiel Diet


In the wild, cockatiels eat a variety of seeds, grains, fruits, and greens. In captivity, they should get a similarly varied diet to meet all their nutritional needs. A good daily diet includes:


  • High-quality pellets (60–70% of the diet)
  • Fresh vegetables (daily)
  • Limited seeds (as a supplement)
  • Occasional fruits (as treats)
  • Fresh, clean water (available at all times)

Pellets: The Foundation of the Diet


Pellets are specially formulated to provide the nutrients cockatiels need and should make up the majority of their diet - around 60–70%.


  • Choose a trusted brand without artificial dyes or flavors.
  • If your bird is used to seeds, transition slowly by mixing pellets into their regular food and increasing the amount over time.


Pellets help prevent the common deficiencies that come from seed-only diets.


Seeds: Use in Moderation


Cockatiels enjoy seeds, but too many can lead to obesity and nutrient imbalances, especially in vitamin A and calcium.


  • Offer a variety of seeds such as millet, canary seed, and small amounts of sunflower seeds.
  • Treat seeds as a supplement, not a staple.

Some cockatiels may try to pick out only seeds - especially sunflower - so portion control is important.


Vegetables: Daily Essentials


Fresh vegetables provide vital nutrients and fiber.


Good options include:


  • Leafy greens: kale, spinach, romaine
  • Carrots
  • Broccoli
  • Bell peppers
  • Sweet potatoes
  • Peas


Wash veggies thoroughly and offer them raw or lightly steamed. Avoid iceberg lettuce, since it has little nutritional value.


Fruits: Occasional Treats


Fruits are safe in moderation and can be a fun part of your bird’s diet, but they’re high in sugar. Limit them to about 5–10% of the total food intake.


Safe fruits include:


  • Apples (without seeds)
  • Berries
  • Grapes
  • Melons
  • Bananas


Always remove pits or seeds from fruits like apples and cherries, as some can be toxic.


What to Avoid


Some foods are toxic or unsafe for cockatiels and should never be offered:


  • Avocado
  • Chocolate
  • Caffeine
  • Alcohol
  • Onions and garlic
  • Salty or sugary foods
  • Processed human snacks (chips, bread, junk food)


Stick to bird-safe foods and avoid anything with additives or preservatives.


Water and Food Safety Tips


  • Provide clean, fresh water daily in a washed dish or water bottle.
  • Remove uneaten fresh food after a few hours to prevent spoilage.
  • Watch for changes in eating habits, which can be an early sign of illness.


Final Tips


A healthy cockatiel diet is all about balance. Stick to a pellet-based foundation, offer a daily variety of vegetables, keep seeds and fruit limited, and avoid harmful foods. With good nutrition and a clean environment, your cockatiel will stay happy, active, and full of energy.
