Safflower is a seed with a hard shell that is difficult for birds with thin beaks to crack open. Ideal to attract northen cardinals, which love it, it is however not very popular with sparrows, starlings, and squirrels.

To attract only cardinals, try the unique cardinal feeder, which filters out other species from accessing the feeder.

Also available in a square shape.

Attracts:

• northern cardinals
• chickadees
• finches
• doves
