What to Feed Your Pet Bird - A Complete UK Guide to Bird Diet and Nutrition
Key Takeaways
- Seeds alone aren't enough - most pet birds need a balanced diet of quality pellets, fresh vegetables, and limited seeds
- Species matters - budgies, cockatiels, canaries, and parrots all have different nutritional needs and portion sizes
- Fresh food daily - dark leafy greens, carrots, broccoli, and small amounts of fruit should be offered every day
- Calcium is critical - cuttlebone, mineral blocks, or liquid calcium supplements prevent egg-binding and weak bones
- Avoid toxic foods - avocado, chocolate, caffeine, onion, and garlic can kill birds even in tiny amounts

Getting your bird's diet right is the single most important thing you can do for their health and happiness. Unlike dogs or cats, pet birds have very specific nutritional requirements that vary hugely between species. A budgie's dietary needs are different from a cockatiel's, and a canary needs something else again.
In this guide, we'll walk through exactly what to feed the most common UK pet birds - budgies, cockatiels, canaries, and small parrots - based on veterinary guidance from the RSPCA and avian nutrition specialists. We'll cover the seed-versus-pellet debate, which fresh foods are safe, what supplements your bird actually needs, and which common foods can be lethal.

The Foundation: Seed Mixes
For most UK pet birds, a good seed mix forms the staple of their diet. But here's the thing - seeds should not be the only thing you feed. Wild birds eat seeds alongside insects, greens, and fruits. Pet birds need the same variety.
For budgies, a premium seed mix like Vitakraft Budgie Food provides a balanced blend of millets, canary seed, and oats. Budgies in the wild eat grass seeds as their main food source, so a good quality seed mix should make up about 50% of their total intake.
Cockatiels need larger seeds and a higher proportion of sunflower and safflower. The SkyGold Cockatiel and Parakeet Food 20kg is a popular choice among UK owners, or for smaller households, the Hari Gourmet Cockatiel Mix 1.3kg offers a well-balanced blend in a manageable bag.
For canaries, you need a finer mix. Canary beaks are smaller and more delicate than budgie or cockatiel beaks. The Hari Gourmet Canary Mix 1kg is specifically formulated for canary-sized beaks, with niger seed, rape seed, and fine millet.
A common mistake is leaving seeds in the bowl for days and letting birds pick out their favourites while leaving the nutritious bits behind. Empty the seed bowl weekly, discard the husks, and refill with fresh mix.
Pellets: The Nutritional Safety Net
Veterinary nutritionists increasingly recommend pellets as part of a bird's daily diet. Unlike seeds, where birds can pick out the fatty sunflower seeds and ignore everything else, pellets deliver complete nutrition in every piece. The Harrisons Bird Food Adult Lifetime 454g is a certified organic pellet suitable for canaries, finches, and budgies. For larger parrots and cockatiels, the Harrisons High Potency Coarse 454g provides extra protein and fat during moulting or breeding.
Pellets should make up around 40-50% of a budgie or cockatiel's diet, with seeds reduced to 20-30%. Introduce pellets gradually - mix them with seeds at first, then increase the proportion over 2-3 weeks. Some birds are stubborn and will refuse pellets initially, but persistence pays off.
Fresh Foods: Vegetables, Fruit and Greens
Fresh vegetables should be offered daily to every pet bird. Dark leafy greens like kale, spinach, and Swiss chard are packed with vitamins A and K. Carrots, broccoli, bell peppers, sweet potato, courgette, and corn are all excellent choices.
A great way to serve fresh food is on a stainless steel fruit skewer - birds love to forage and peck at food that's hanging, and it keeps veg clean and off the cage floor.
Fruit should be offered in smaller amounts - no more than 10% of total diet due to sugar content. Apple (seeds removed), berries, melon, orange segments, and banana are all safe. Wash everything thoroughly and chop into beak-sized pieces. Remove uneaten fresh food after 2-3 hours to stop it spoiling.
Never feed: avocado, chocolate, caffeine, alcohol, onion, garlic, rhubarb, apple seeds, fruit pits, raw beans, or mushrooms. These are genuinely toxic to birds and can cause rapid illness or death.
Treats, Supplements and Calcium
Treats are a great training tool and enrichment activity, but they should make up no more than 5% of your bird's diet. Seed sticks and honey treats are popular, like the Tweeters Treats Seed Sticks for Parrots or Quiko Bird Treats Mini Pop Corn 170g. These are fine as occasional rewards - not daily staples.
Calcium is non-negotiable. Every caged bird needs access to a calcium source. A cuttlebone should be attached to the cage bars at all times. Your bird will peck at it as needed, and it helps keep their beak trimmed too. For extra calcium, a mineral block provides iodine and other trace minerals alongside calcium.
For breeding hens or birds showing signs of calcium deficiency, a powdered supplement like Nutrobal Calcium and Vitamin D3 Supplement can be dusted onto fresh food once a week. Always check with a vet before adding supplements - more isn't always better.
Quick Reference: What to Feed by Species
| Species | Seed % | Pellet % | Fresh Food | Daily Portion |
|---|---|---|---|---|
| Budgie | 50% | 40% | 10% | 1.5-2 tsp total |
| Cockatiel | 30% | 50% | 20% | 2-3 tbsp total |
| Canary | 60% | 25% | 15% | 1-1.5 tsp total |
| Small Parrot | 20% | 60% | 20% | 3-4 tbsp total |
These are general guidelines. Adjust based on your bird's activity level, health, and your vet's advice.
Five Common Bird Diet Mistakes
1. All-seed diet. A bowl of mixed seed and nothing else is the nutritional equivalent of feeding your child only cereal. Seeds are high in fat and low in calcium and vitamin A. Add pellets and fresh food every day.
2. Letting them pick favourites. Birds will eat the tasty seeds first and leave the rest. Empty the bowl weekly - don't just top it up. Otherwise your bird ends up eating only sunflower seeds, which is like living on chips.
3. Forgetting calcium. Soft-shelled eggs, egg-binding, and weak bones are all signs of calcium deficiency. Every bird cage needs a cuttlebone or mineral block, always accessible.
4. Too many treats. Honey sticks, seed bells, and millet sprays are treats, not food. One small piece of treat per day is plenty. More than that encourages obesity and fatty liver disease.
5. Stale or mouldy food. Bird seed can go rancid, especially in warm kitchens. Store seed in a cool dry place and check for weevils or mould before refilling. Throw away any food that looks or smells off.

Final Verdict
A healthy bird diet comes down to three things: variety, quality, and consistency. Start with a good quality seed mix appropriate for your species, add a complete pellet like Harrisons Adult Lifetime or High Potency for nutritional insurance, and offer fresh vegetables every single day. Keep a cuttlebone in the cage at all times and treats to a minimum.
The UK bird food market has improved massively in the last decade. It's never been easier to feed your feathered friend a properly balanced diet - you just need to know what to look for and avoid the marketing hype around all-seed mixes and sugary treats.
Your bird can't choose what it eats. That's your job. Get it right and you'll have a healthier, happier, longer-lived companion. If you're ever unsure, your local avian vet is the best source of species-specific advice.
