For many gardeners, feeding the birds that visit their gardens can be one of the most enjoyable garden tasks. However, wildlife experts are warning against three food items that you should never put in your bird feeder.

Leaving out food during the autumn and winter can provide a vital energy source for our feathered friends, especially as the RSPB reports that bird species are declining in the UK. There are so many reasons why it is a good idea to learn what to feed birds in your garden, as attracting them not only helps to pollinate flowers, but it can also help with pest control.
