Drew made this "grackle-proof" feeder from a plant saucer, an old suet feeder and bits & bobs found in the shed. It might be more accurate to call this a "grackle-resistant" feeder as these birds are incredibly smart and persistant. But at least now a block of suet lasts a few days instead of a few hours! As you watch the video, notice that each species of bird has their own style of feeding. Some are built for clinging upside down, others not so much.
