Wagner's Safflower Seed - Cardinals love it, squirrels dont. Safflower seed is a great way to attract the birds you want - Cardinals, Chickadees, Titmice, Grosbeaks - and discourage the "feeder hogs" like Grackles and Starlings that keep them away. And best of all, squirrels dont like the taste so they will stay away as well. If you have unwanted birds and squirrels crowding out your songbirds we recommend filling your feeder with Wagners Safflower Seed for a period of time, then gradually mix in your favorite Wagners premium wild bird food. Wagners Safflower Seed is truly a premium, high value seed not found in ordinary blends. So give the Cardinals their favorite seed and keep the pests away at the same time, with Wagners Safflower Seed. Trust your backyard birds to the experts at Wagners.
