Cockatoo Feeding: Schedule, Diet, and the Ratio Worth Memorizing
On This Page▾
Cockatoo feeding comes down to a ratio worth memorizing: pellets should dominate the bowl, and seeds should stay firmly in treat territory, not the other way around.
The Staple Diet
Pelleted food should make up 75 to 80% of your cockatoo's daily diet. Fresh vegetables make up most of the remaining 20 to 25%, with fruit a smaller share and seeds under about 10%. Dark leafy greens like kale and bok choy, plus carrots, bell peppers, broccoli, squash, and peas all work well. Pale, watery vegetables such as iceberg lettuce and celery add little and can be skipped. A couple of tree nuts, almonds, walnuts, or Brazil nuts, make a fine daily treat and double as enrichment for a bird this intelligent.
How Much a Cockatoo Eats in a Day
An adult umbrella cockatoo typically eats about 1/4 to 1/2 cup of pellets and pellet-based food a day, with fresh vegetables on top. Individual birds vary with size, activity and how much fresh food they get, so the cup figure is a starting point for any species.
Cockatoos grind pellets to crumbs, which makes a full-looking dish hard to read. The way to find a bird's real intake:
- Measure the pellets that go into the bowl each morning.
- Next morning, measure what is left, including the larger discarded pieces.
- Repeat for three to five days and average the amount eaten.
That average is the daily portion, and it is the number to hand a boarding facility or a pet sitter. Pack a margin for waste on top of it.
Feeding Frequency and Portions
Offer fresh food daily, and keep fresh water available at all times, cleaning both food and water dishes every day. A useful mental picture from veterinary guidance: a small handful of food for your cockatoo is roughly equivalent to a full dinner plate for a person, it's easy to over-portion without realizing it. Fruits and vegetables shouldn't sit in the cage more than a couple of hours before spoiling. Hand-raised babies should be started on pellets. A mature cockatoo raised on seed can be hard to convert, so do it gradually and weigh the bird periodically during the transition to make sure intake stays adequate. If a bird fixates on one food, cut the amount of it or drop it for a while so the rest of the bowl gets eaten.
Foods to Avoid
Avocado, chocolate, caffeine, and alcohol are all toxic and can be fatal, keep these away entirely. Fruit pits and apple seeds release cyanide-related compounds, and onion and garlic can cause a serious blood disorder in birds.
Beyond acute toxins, the bigger long-term risk is simply too much seed. Cockatoos love sunflower seeds and peanuts, and a cockatoo given a seed mix will pick those out and leave the rest. Both are high in fat and short on calcium and vitamin A, so they stay occasional treats. Skip grit or gravel too: cockatoos already hull seeds before swallowing them, and grit can cause a dangerous digestive blockage.
Supplementation
A bird eating a complete pelleted diet at 75 to 80% generally doesn't need additional vitamin or mineral supplements, that formulation is already fortified to cover it. Supplements matter more for a bird still transitioning off an all-seed diet, and any specific supplementation decision, egg-laying hens needing extra calcium, for instance, is worth making with your avian vet rather than adding something preventively.
The Mistakes That Matter
A seed-heavy diet is the central feeding mistake with this species, and it's directly linked to fatty liver disease, obesity, and vitamin A deficiency. Cockatoos are also vulnerable to low dietary calcium, high cholesterol with the artery buildup of atherosclerosis, and egg-binding in hens, and all of those trace back to the same bowl.
High-fat diets specifically are also tied to lipomas, fatty skin tumors that show up notably often in overweight cockatoos and several other parrot species, while birds actually eating their pellets develop them far less. And even on a good base diet, regular calorie-dense treats or an overfed hand-raised baby can still tip a cockatoo toward obesity and the same fatty liver risk, portion awareness matters even when the food itself is right.
Diet isn't the only thing shaping a cockatoo's daily wellbeing, boredom and under-stimulation feed into the same behavioral problems covered in Cockatoo Screaming and Feather Plucking, Explained.

❓ Frequently Asked Questions
What should make up most of a cockatoo's diet?
Pellets, at 75 to 80% of the daily diet. Fresh vegetables make up most of the remaining 20 to 25%, with fruit smaller and seeds under about 10%: dark leafy greens, carrots, bell peppers, broccoli, squash, and peas. Seeds and nuts are high-fat treats, not the foundation.
How much food does a cockatoo need daily?
For a healthy adult umbrella, somewhere between a quarter cup and half a cup of pellet food, with vegetables alongside. Size and activity move that number, so track what the bowl loses over several days for the figure that fits one bird.
What foods are toxic to cockatoos?
Avocado, chocolate, caffeine, and alcohol, all of which can be fatal. Cyanide-related compounds come from fruit pits and apple seeds, and onion and garlic can cause a serious blood disorder. Grit and gravel are out too: cockatoos hull their seeds already, and grit can cause a dangerous blockage.
How do I switch my cockatoo from seeds to pellets?
Gradually, weighing the bird now and then through the transition so intake stays adequate. Once it's on a complete pelleted diet at 75 to 80%, extra vitamin or mineral supplements generally aren't needed, though a bird still coming off all-seed may need them.
Why is a seed-heavy diet dangerous for cockatoos?
Fatty liver disease, obesity, and vitamin A deficiency are all directly linked to it. High fat is also tied to lipomas, the fatty skin tumors seen often in overweight cockatoos and other parrot species.
