Most of the birds coming to your feeders will be seed eating birds and their favorite is the black oil sunflower seed. According to experts this seed has a high amount of meat as compared with other bird seeds and is a great source of protein. This is the best bird feeder seed to use. The soft shell makes it easy for the smaller birds to get access to the seed. In winter the oil in this seed is important to birds as they use their oil glands to spread this oil over their feathers to help keep them dry and warm.
