Blue jays eat insects, fruit, nuts, seeds, and occasionally even eggs and baby birds.
Blue jays love sunflower seeds, and are perfectly capable of shelling them if you don’t provide shelled seeds.
They will also eat other kinds of seed, so you can offer a seed mix or spread out things such as millet, wheat grains, etc.
They also love corn kernels and will eat these with great enthusiasm, very quickly.
These bright birds also eat nuts. They are fond of acorns and beechnuts.
Blue jays eat a lot of insects, such as caterpillars, grasshoppers, moths, beetles.
If you have a caterpillar infestation, blue jays are a wonderful natural solution!
