Make a Pinecone Bird Feeder
The Cornell Lab’s Citizen Science Blog has a recipe for making your own pinecone feeders with seeds and suet attached to them.
“For birds, it means having access to nutrient-rich, fat-laden nuts, seeds, and even straight-up fat (like in suet). Consider making these easy to assemble pinecone suet feeders so your bird-neighbors have enough energy to survive the winter. Unlike us, they actually need that extra helping of fat this time of year!”
