If you have never fed Suet, you may have missed some great birds. Suet is one of the top three foods to feed wild birds. Birds have high metabolic rates. It is not unusual for birds to consume 1/4 to 1/3 their body weight worth of food a day! Offering suet cakes provides a high caloric energy source.
That’s why most people buy the prepared suet cakes we sell at Wild Birds Unlimited. Our suet cakes are made with only the highest quality processed beef kidney fat. Special processes remove impurities that cause low melting points and spoilage problems. Or you can render suet yourself.

According to the Cornell Lab of Ornithology “bacon drippings are also animal fat and many birds love the taste. But bacon virtually always has detectable amounts of nitrosamines, carcinogenic compounds formed from some of the preservatives used in bacon. In particular, the very high cooking temperatures used to fry bacon are conducive to nitrosamine formation. So despite the fact that birds love it, bacon and bacon fat pose too much of a risk to the long-term health of birds to warrant using it.”
