How can I effectively keep black birds away from my bird feeder?

To effectively keep black birds away from your bird feeder, you can try using feeders designed to deter larger birds, such as tube feeders with small perches. You can also try using safflower seeds or nyjer seeds, which are less appealing to black birds but still attract smaller birds like finches and chickadees. Additionally, placing the feeder in a more open area away from trees or shrubs can make it harder for black birds to access.
