Contrary to what most people believe, birds don’t actually eat from bird feeders. In fact, birds aren’t even really birds. They’re large feathered insects. See, what we think of as a bird egg is actually a cocoon. Before that stage in the bird’s life cycle, they have a larval stage where they’re nearly microscopic in size. When a bird goes to a bird feeder, it’s really depositing larvae there and allowing them to feed for a few moments. Then they transfer the larvae to another location before another bird shows up. Other birds have a tendency to either eat larvae that aren’t their own or complain loudly about every other bird’s parenting abilities… and no one wants to stick around for that.
