The bird seed calculator estimates how much seed your backyard feeder birds consume daily and monthly, so you can buy the right amount and keep feeders full without waste.

How to Calculate Bird Seed Consumption
Bird seed consumption depends on feeder size, refill frequency, bird traffic, and season. Winter feeding typically uses 30-50% more seed as birds need more calories in cold weather.
Buying in Bulk
Buying larger bags (40-50 lbs) is usually 30-50% cheaper per pound than small bags. Store seed in a sealed metal or hard plastic container to keep it fresh and rodent-free. Most seeds stay fresh for 6-12 months when stored properly in a cool, dry location.
Frequently Asked Questions
Is this bird seed calculator free?
Yes, completely free with no signup required.
How much seed should I feed my parakeet?
Parakeets (budgies) need approximately 1-1.5 teaspoons (5-7.5 ml) of seed per day. However, a seed-only diet is nutritionally deficient. Ideally, seeds should make up only 20-30% of a parakeet's diet. Supplement with pellets (50-60% of diet) and fresh vegetables/fruits (20-30%) for optimal health and longevity.
Should I feed my parrot seeds or pellets?
Pellets are recommended as the dietary foundation (50-70% of diet) because they provide complete, balanced nutrition. Seeds are high in fat and low in vitamins and minerals — a seed-only diet leads to vitamin A deficiency, liver disease, and shortened lifespan in parrots. Fresh vegetables, fruits, and cooked grains should make up the remaining 30-50%.
How often should I change bird food?
Fresh food (fruits, vegetables, cooked grains) should be removed after 2-4 hours to prevent spoilage and bacterial growth. Seeds and pellets can remain in the food dish for 1-2 days before replacing. Never allow food to become moldy. Clean food dishes daily with soap and water.
What foods are toxic to birds?
Toxic foods for birds include: avocado (all parts — highly toxic), chocolate, alcohol, caffeine, onions, garlic, apple seeds and pits (cyanide), high-sodium foods (crackers, chips), xylitol (artificial sweetener), raw dry beans, and mushrooms. Never offer these regardless of bird species.
