TRAILMARK NATURALS 15 lb Black Oil Sunflower Seeds are a high-energy, non-GMO bird feed designed to attract a wide variety of wild and backyard birds to feeders and feeding stations.
If you want dependable seed that birds readily recognize and favor, this 15-pound bag of black oil sunflower from TRAILMARK NATURALS delivers large kernels, thin shells, and consistent quality sourced and packed in the United States. It suits multiple feeder styles and feeding habits, making it an easy choice for both new and experienced birdwatchers who want reliable results without additives.
Black oil sunflower is among the most universally attractive seeds for backyard species. Its high oil content and manageable shell size appeal to finches, chickadees, cardinals, nuthatches, grosbeaks, and many ground-feeding species as well. The seed’s nutrition and ease of cracking mean more species will feed actively at your station.
These black oil sunflower seeds are versatile and feed well from tray, hopper, and tube feeders. Thin shells reduce waste and make the kernels accessible to smaller-beaked species, while the kernels also remain stable in open trays and platform feeders. Fill feeders according to capacity and local weather to prevent spoilage.
Store unopened bags in a cool, dry place away from direct sunlight to preserve oils and prevent rancidity. After opening, reseal or transfer to an airtight container to minimize pest access and moisture. Replace old or moldy seed immediately, and clean feeders regularly to reduce disease risk among visiting birds.
TRAILMARK NATURALS sources and packs these black oil sunflower seeds in the USA, working with domestic growers to maintain traceability and consistent kernel quality. The non-GMO designation indicates seeds are from conventional varieties that have not been genetically modified. This lets buyers support U.S. agriculture while choosing a straightforward seed option for wildlife feeding.
Who is this for? TRAILMARK NATURALS 15 lb Black Oil Sunflower Seeds are ideal for homeowners, backyard birders, and wildlife enthusiasts who want an all-around, high-energy seed that draws a broad mix of species. It’s also practical for parks, nature centers, or anyone who prefers larger bags for frequent feeding—especially those who prioritize U.S.-sourced, non-GMO options and easy feeder compatibility.
