Why choose black oil sunflower seeds for backyard feeders?

Black oil sunflower seeds are prized for their high oil content and thin shells, which make them easy for small-bodied birds to open and digest. Their oil-rich kernels provide energy during migration and colder months, while the shells often leave less waste under feeders than larger-seeded mixes.

• High oil content for sustained bird energy
• Thin shells that many small songbirds can crack easily
• Less filler—more kernel per pound compared with mixes
• Effective at attracting a wide variety of species

How well does TRAILMARK NATURALS seed work in different feeder types?

This black oil sunflower seed performs reliably across tray, hopper, and tube feeders as well as in platform placements. The small, consistent seed size flows well in tube ports and doesn't clump in most hoppers, while tray feeders allow ground-feeding species easy access.

• Tube feeders: flows smoothly through standard ports
• Hopper feeders: refills evenly without jams
• Tray/platform: ideal for ground or open feeding
• Hand scattering: suitable for attracting ground-foraging birds

What birds will you attract with this black oil sunflower seed?

Expect to see a broad mix of backyard favorites: finches, chickadees, titmice, cardinals, nuthatches, and younger or smaller individuals of larger species. Because of the thin shells and rich kernels, both small songbirds and many medium-sized birds find them easy to consume.

• Common visitors: chickadees, titmice, finches, and nuthatches
• Attracts cardinals and many medium songbirds
• Appeals to both feeder- and ground-feeding species
• Good for year-round feeding and migration stopovers

How should I store and handle the 10 lb bag for best freshness?

Keep the bag sealed and stored in a cool, dry place away from direct sunlight to preserve oil quality and prevent rancidity. For longer-term storage, transfer seed to an airtight container elevated off the ground and away from rodents and moisture.

• Store in a cool, dry area out of direct sun
• Use an airtight bin to prevent pests and odor transfer
• Rotate stock—use older bags first to maintain freshness
• Keep off floors to reduce pest access and moisture risk
