The term 'Bird Feed' can be broken down into two crossword solutions: SUET (4 letters) and SEEDS (5 letters). SUET is a type of animal fat, usually beef or mutton, that is used to make bird feed. It is often mixed with other ingredients such as grains, nuts, and dried fruit to create a nutritious meal for birds. Seeds are also a popular choice for bird feed, as they provide a variety of nutrients and energy for birds.
