Mr. Bird Safflower Feast Large Wild Bird Seed Cylinder 5 lbs - Premium Safflower Seed for Wild Birds - Attracts Cardinals, Finches & Woodpeckers - Perfect for Backyard Bird Feeders & Wildlife Gardens

I bought this large safflower seed cylinder because the starlings and house sparrows had found my feeders. I took down the other feeders and used the safflower cylinder exclusively. The starlings could not cling very well, nor could the house sparrows, so they gave up and went away. The nuthatches, cardinals, and other local birds have learned to use the cylinder. I would recommend that you use a roof or cover over the cylinder to keep the rain off. I also hung a tray feeder beneath to catch any dropped seed. I will only use the saff cylinder in my mission to thwart starlings. When the starlings go away I put out black oil sunflower seed. I use the nut and seed cylinder when I am away from home for days—they seem to last a long time without refills and all the woodpeckers and other birds like that one..
