About This Calculator

Keep your feathered friend flying high with the Bird Nutrition Calculator. Avian diets are often misunderstood—a "seed only" diet is like a human living on junk food. Just as people track daily calorie needs, pet birds require carefully balanced nutrition for optimal health and longevity.

Seeds, while natural, are high in fat and low in essential vitamins. Birds on seed-only diets commonly develop fatty liver disease, vitamin A deficiency, and shortened lifespans. Modern avian nutrition recommends pellets as the dietary foundation, supplemented with fresh vegetables and limited seeds as treats.

Birds have extremely high metabolic rates relative to their size. Smaller species like finches and canaries may consume 15-30% of their body weight daily, while larger parrots eat closer to 10-15%. This high metabolism means even short periods without food can be dangerous—always ensure your bird has access to fresh food.

Daily Food Calculation

Daily Food = Body Weight (g) × Size Factor

Small birds (finch/canary): 20% of body weight

Medium birds (cockatiel/conure): 15% of body weight

Large birds (macaw/cockatoo): 10% of body weight

Bird Size & Nutrition Reference

Bird Type	Avg Weight	Daily Food	Diet Ratio
Finch/Canary	12-30g	3-6g	60% pellets, 20% seeds, 20% fresh
Budgie/Lovebird	30-60g	5-10g	70% pellets, 10% seeds, 20% fresh
Cockatiel	80-120g	12-18g	70% pellets, 10% seeds, 20% fresh
Conure	60-120g	10-18g	70% pellets, 10% seeds, 20% fresh
African Grey	400-600g	40-60g	80% pellets, 5% seeds, 15% fresh
Macaw	900-1500g	90-150g	80% pellets, 5% seeds, 15% fresh

Practical Example

For a 100g cockatiel: Daily food = 100g × 15% = 15 grams total. This breaks down to approximately 10.5g pellets (70%), 1.5g seeds (10%), and 3g fresh vegetables (20%). Offer in morning; remove uneaten fresh food after a few hours.

Safe Foods for Pet Birds

Vegetables: Leafy greens, carrots, bell peppers, broccoli, squash
Fruits (limited): Berries, apple (no seeds), banana, mango
TOXIC - Avoid: Avocado, chocolate, caffeine, alcohol, onion, garlic

Bird Feeding Tips

Transition from seeds to pellets gradually over 4-8 weeks
Offer fresh water daily; birds won't drink stale water
Rotate vegetable types for nutritional variety
Never feed birds from your mouth—human saliva contains harmful bacteria

Scenario Comparison: Daily Food by Bird Size

Bird Type	Weight	Total Food	Diet Breakdown
Budgie/Parakeet	30-40g	5-8g daily	70% pellets, 20% seeds, 10% fresh
Cockatiel	80-120g	12-18g daily	70% pellets, 10% seeds, 20% fresh
African Grey	400-600g	40-60g daily	75% pellets, 5% seeds, 20% fresh
Macaw	900-1500g	90-150g daily	60% pellets, 15% nuts, 25% fresh

Common Bird Feeding Mistakes to Avoid

Seed-only diet: Seeds are high in fat, low in vitamins. Leads to fatty liver disease, feather problems, and 50% shorter lifespan. Transition to 70%+ pellets.
Feeding avocado, chocolate, or caffeine: These are toxic to birds. Even small amounts can cause heart failure within 24 hours.
Not providing enough variety: Birds need diverse vegetables, fruits, and occasionally cooked grains. Offer at least 3-4 different foods daily.
Ignoring calcium needs: Breeding females and egg-laying birds need cuttlebone or mineral blocks. Deficiency causes egg-binding and brittle bones.

When to Use This Calculator vs Others

This calculator: Best for parrots, canaries, finches, and other pet birds to determine pellet, seed, and fresh food portions.
Pet Meal Calculator: Use for dogs and cats—their calorie and nutrition needs are very different from birds.
Fish Nutrition Calculator: Use for aquarium fish which have completely different feeding schedules.
Small Mammal Nutrition: Use for rabbits and guinea pigs—herbivores with hay-based diets.

Frequently Asked Questions

How is bird food amount calculated?

Daily food = body weight × 10-20%. Small birds: 20% of weight. Large parrots: 10%. 100g cockatiel needs ~15g food daily (70% pellets, 30% fresh).

Should pet birds eat only seeds?

No—seed-only diets cause fatty liver disease and vitamin deficiency. Ideal: 70-80% pellets, 10% seeds, 10-20% fresh vegetables. Transition gradually.

What foods are toxic to pet birds?

Avocado, chocolate, caffeine, alcohol, onion, garlic, and apple seeds are toxic. Also avoid high-salt, high-sugar, and fried foods.
