Both peanut butter and cornmeal are nutritious for birds. Peanut butter contains high levels of fat and protein similar to what they would get from eating insects. Cornmeal contains fat, fiber, iron, phosphorus, potassium, magnesium and folate which are all beneficial to bird health.
Combining 1 cup of peanut butter and 1 cup of corn meal renders a cornstarch-like texture safe for bird consumption. Seeds, dried fruits and crushed nuts can also be added to the mixture to add flavor, scent and nutrients.
Pine cone bird feeders are a classic childhood craft and an environmentally safe way to serve peanut butter and cornmeal to birds. Pine cone feeders are suspended pine cones dipped in peanut butter and rolled in cornmeal, seeds, dried fruits or chopped nuts.
Peanut butter cornmeal cakes are hand-molded cakes in the form of a disk or ball with equal parts peanut butter and cornmeal. Seeds can be sprinkled into the mixture to create a more cake-like consistency. The cakes are dried and hung on string or placed on bird feeder decks.
Peanut butter should never be given straight to a bird. Peanut butter consistency is very thick and sticky which can cause birds to choke.
