This large 100% seed cylinder is excellent for squirrel-prone areas, as squirrels generally don’t like safflower. These cylinders are preferred by cardinals, grosbeaks, and more, while grackles, sparrows, and starlings generally don’t like safflower. The golden safflower has a thinner hull than traditional safflower seed so attracts a greater variety of birds. Mount on a Mr. Bird EZFeeder (Item 800) or cylinder feeder (item 803). The huge size means this block will last for weeks, no more running out to refill the feeders every day. No waste, no mess, never melt. Attracts birds much more quickly than suet and without the problem of melting in the summer heat. Great for year-round bird feeding in squirrely areas. Compatible feeders: 800 or 803. Packaging information: barrier packaging.
