Raisins
Birds LOVE raisins. The northern flicker, robins, bluebirds, thrushes, buntlings, thrashers and many more! Add raisins to any homemade suet cake and your neighborhood birds will come back for more.
Raisins are a great way for birds to gain some weight during the cold Winter months, in a healthy way. Raisins also have calcium, which is good for bone health in birds.
Raisins are also widely available at most every grocery store and local market, making it a very easy ingredient to add to a simple homemade suet cake.
