Seed & Feeder Matcher
Tick the birds you actually want and see which seed and feeder serve the most of them — with the trade-offs shown, because no single seed pleases everyone.
Mode A — pick your birds
Mode B — start from a seed
Black-oil sunflower vs. nyjer vs. safflower — what each seed actually attracts, what it deters, and what it costs per bird fed.
Questions
What is the single best bird seed?
Black-oil sunflower. Thin shell that even small birds can crack, high fat content, and the first or second choice of more North American feeder species than anything else. One feeder, one seed, no debate.
What seed keeps squirrels and grackles away?
Safflower. Cardinals, House Finches, chickadees, titmice, and grosbeaks eat it readily; squirrels, grackles, and starlings generally find it bitter and move on. Switching a tray from sunflower to safflower is the cheapest crowd control there is.
Why do birds throw my mixed seed on the ground?
They're sorting, not wasting. Cheap mixes are bulked out with red milo, wheat, and oats that most feeder birds refuse, so the birds flick filler aside to reach the sunflower underneath. Buy single seeds, or a mix with no milo in the ingredient list.
My goldfinches disappeared from the nyjer feeder. Why?
Almost always stale seed. Nyjer's oil content goes rancid within a few months and goldfinches will not touch it. Dump the tube, wash and dry it, refill from a fresh bag, and buy nyjer in quantities you'll use in a season.
Where should I put the feeder so birds don't hit my windows?
Within three feet of the glass, or more than thirty feet away. Very close means a startled bird can't reach lethal speed; far away means it won't mistake a reflection for sky. The middle distance is what kills.
Do I need to take feeders down in summer?
No. Feeding year-round doesn't make birds dependent — feeders are a supplement, not a diet. Do keep them clean: warm weather grows bacteria on a wet tray fast. Scrub every couple of weeks in summer, and take a feeder down entirely if you see a sick bird.
