Bird feeder food typically consists of two main components: SUET and SEED. SUET is a type of animal fat that is often used to attract birds to bird feeders. It is usually sold in cake form and can be found in most pet stores. SEED, on the other hand, is a type of grain that is also used to attract birds to bird feeders. It is usually sold in bags and can also be found in most pet stores. Both SUET and SEED are essential components of bird feeder food and are necessary for attracting birds to bird feeders.
