Berkley Jensen is the house brand of BJ’s Wholesale Club, and its Premium Select Blend wild bird food is a seed mix sold in large bags for backyard feeders. The product description lists sunflower seeds, white proso millet, cracked corn and safflower. Always confirm the exact ingredients on the bag you buy, since blends can change.
What the ingredients attract
- Sunflower seeds: high in fat and a favorite of cardinals, chickadees, titmice, nuthatches and finches.
- White proso millet: popular with ground feeders such as doves, sparrows and juncos.
- Cracked corn: draws ground feeders, but also attracts pigeons, grackles and squirrels, and it can spoil quickly when wet.
- Safflower: liked by cardinals and finches and usually less attractive to squirrels and grackles.
Which feeders work
A mix like this suits hopper and platform feeders best, where both perching and ground-feeding birds can reach it. Tube feeders can work, but millet and corn may fall to the ground, so place a tray or a ground-feeding spot underneath. Offer seed in small amounts and refill often rather than overfilling.
Buying and storage tips
- Choose mixes with a high share of sunflower and a low share of filler grains like milo and wheat, which many birds toss aside.
- Store seed in a sealed metal or heavy plastic bin in a cool, dry place to keep out moisture, mold and rodents.
- Throw out damp, clumped or moldy seed and clean feeders every couple of weeks with a mild bleach or vinegar solution, rinsing well.
Is it a good value?
A warehouse-club bag is a good choice if you have many birds or several feeders. If you only feed a few birds, a smaller bag avoids stale seed. For more ideas, read what to feed wild birds besides seed and our wild bird seed at Tractor Supply guide.
Bottom Line
A sunflower, millet and safflower blend is a solid all-purpose songbird seed. Check the bag for the ingredient list, store it dry, and keep feeders clean to protect the birds.
