When buying seed for your feeders, it’s tempting to get the biggest, cheapest bag. But not all bird seed is the same.

Other good seeds include white millet and nyjer thistle. Avoid red milo, a livestock grain. And clean your feeding station regularly to prevent the spread of disease. Learn more at BirdNote.org.
