Bird Seed Guide: Choosing the Right Seed for Your Target Species
Choosing the right bird seed is the single most important decision in backyard birding. The wrong seed attracts the wrong birds (or none at all), wastes money, and creates messy piles of hulls. Understanding seed types and their target species transforms your feeding program from guesswork to precision.

Avoid These Fillers
Cheap seed mixes often contain filler seeds that most birds reject: red millet, wheat, oats, and whole corn. These fillers create waste and attract rodents. Invest in quality seed blends or buy individual seed types for your target species.
Best Value Seed
Black oil sunflower seeds offer the best value: nearly every bird eats them, they have thin shells (less waste), and high fat content (more nutrition). Buy in bulk for the best price per pound.

Seed Statistics
Q: How much bird seed do I need per week?
A: A typical feeder uses 1–2 pounds per week in peak season. Winter usage doubles. Buy seed in bulk and store in airtight containers to maintain freshness.
