Bird seed consumption and cost calculator
Store seed in a sealed metal can so mice and moisture cannot reach it.
If a feeder empties in a day, squirrels or blackbirds are probably eating a large share; a baffle or safflower cuts the bill.
The default price per pound is the median of the black oil sunflower bags we list that state a weight, currently about $1.90. Bigger bags cost less per pound; hulled hearts cost more per pound but waste nothing.

How much bird seed do feeders use in a month?
It depends almost entirely on how many birds find the feeder and whether squirrels get to it. A single tube feeder in a quiet yard may use 5 to 10 pounds a month, while two busy feeders in winter can go through 40 pounds or more. Timing how long one full feeder lasts is the most reliable way to estimate your own use.
Is it cheaper to buy bird seed in bulk?
Usually yes. Twenty to fifty pound bags of black oil sunflower or safflower cost noticeably less per pound than five pound bags. The catch is storage: seed must stay dry and away from rodents, so a galvanized can with a tight lid is part of the saving. Hulled seed and nyjer go stale faster and are better bought in smaller amounts.
Why do birds eat more seed in winter?
Small birds such as chickadees burn a large share of their energy just staying warm through long, cold nights, and natural foods such as insects and fresh seed are scarce. Feeder use typically climbs through late autumn and peaks in the coldest weeks. In summer, insects and wild seed are plentiful and feeder traffic drops.
Does no-mess seed save money?
Often. Hulled sunflower hearts cost more per pound, but you pay only for food, not shell weight, and nothing is kicked to the ground or sprouts under the feeder. Cheap mixes full of milo and red millet can cost more per pound actually eaten, because many feeder birds flick those grains out onto the ground.
How can I stop seed disappearing so fast?
The usual culprits are squirrels, blackbirds and a feeder that spills. Put the feeder on a baffled pole away from launch points, switch to safflower if grackles or squirrels are the problem, use a feeder with seed trays or smaller ports, and avoid mixes heavy in filler grains that birds throw on the ground.
