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 great variety of birds. Offer the large cakes in the Mr. Bird NeatFeeder XL (item 804)/ or Mr. Bird NeatFeeder for the small cake (item 801) or on a platform feeder, it can’t be kicked all over the place like a loose seed can. Large size lasts a long time and attracts loads of birds. 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. Compatible feeders Small Cake: 800, 803, 801. Compatible feeders Large Cake: 804 Packaging information: barrier packaging.
