Nyjer seed. Favorite food of goldfinches. Trust your backyard birds to the experts at wagner’s. Nyjer seed is the absolute favorite of finches, such as the american goldfinch, house finch, purple finch, pine siskin and other small songbirds. This tiny delicacy is used in finch feeders which have smaller holes and tiny perches - perfect for the finches but discouraging to larger birds. Wagner’s nyjer seed is the perfect choice for nurturing finches with its high fat and protein content. Nyjer seed is the only major wild bird food ingredient imported from overseas. Sometimes referred to as "black gold," nyjer seed may seem more expensive than some premium blends, it actually lasts longer as it packs an incredible 150,000 seeds per pound and the seeds create no waste, no mess, no growth and more visits to your feeder. Fill your finch feeder with wagner’s nyjer seed and enjoy the antics of these beautiful and sociable birds in your backyard.
