The Johnston & Jeff Wild Bird Food has been designed to appeal to the widest variety of birds, making it a great choice for year round feeding. It contains small seeds, cereals and vegetable oils to increase feeding values. And, it has a high proportion of sunflower seeds to ensure corrcet nutritional values. Johnston & Jeff pride themselves on producing high quality bird feed and do not include cheap fillers such as whole oats that have little nutritional value. If you use this feed in both a seed feeder and on a table then there are very few birds who will not eat this mix.
