This 100% seed block is excellent for squirrel prone areas, as squirrels generally don’t like safflower. These blocks are preferred by cardinals, grosbeaks and more, while grackles, sparrows, and starlings generally don’t like safflower. Golden safflower seed has a thinner hull than traditional safflower, so will attract a greater variety of birds. Offer these in the Mr.Bird NeatFeeder  or on a platform feeder, it can’t be kicked all over the place like loose seed can. Hole in the center of the cake allows it to be used on the EZFeeder or Cylinder Feeder. 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.
