What raids bird feeders during the night?

That could be, they mostly dine on suet not the sunflower bird feeder, it is squirrel/racoon proof.

Knowing What Birds Eat Bird Seeds at Night will help you protect your bird feeder from some species that visit at night. Usually some rodents such as mice, rats, squirrels or chipmunks often visit the bird feeder because they love seeds, cereals, in addition to corn and black oil sunflower seeds. In addition, some large species such as bears or raccoons visit your garden. They forage for food and can also destroy bird feeders.
