Seasons
Most woodpeckers do not migrate but stay in the same area across the seasons. However, as seasonal changes occur, they will change their diet accordingly and consume whatever is available. Contrary to some beliefs, they do not actually eat the wood that they peck at, although tree sap is one of their nutritional sources.
Spring and Summer
Not much food is available for woodpeckers in the spring, and this is when they are most likely to consume tree sap. In the summer there is more variety, and it's important for breeding birds to access adequate levels of protein. Therefore the main food at this time of year will be insects and particularly things like grubs that can commonly be found in decaying wood and trees.
Fall and Winter
There is more food available for woodpeckers in the fall. This is because nuts, seeds and berries have ripened and so these birds will again alter their diet and consume them. The cold winter months do not offer much variety. Insects are not as easy to obtain because of the often freezing conditions. This is one reason why access to decaying wood is considered vital for the woodpecker's survival.
Feeding by Humans
Attracting wild birds to your garden by offering food is not only enjoyable and rewarding but also bring harmony and balance to your outdoor spaces. Woodpeckers are also good for the environment. They eat wood-boring insects, which are garden pests. They also like to eat other insect pests including crickets, ants and beetles. Because of their versatile diet it's quite easy to attract woodpeckers to your garden. They are particularly fond of suet and you can even get specially designed suet feeders. They will also enjoy sunflower seeds, cracked corn and apples.
