The Bird Food
Garden birds much like humans each have their own tastes and this means that what a Robin may love, a Blue Tit might ignore. To remedy this there isn’t much to be done, so aim to offer as many food types as you can to attract as many feathered friends as possible.
Not only is the type of bird food important, its freshness is too. Birds are likely to ignore food and fat balls that are solid or mouldy in search of something fresher, so make sure to rotate your feed regularly even if they don’t seem to have taken to it yet.
Another way to reduce waste is to only put out enough food to last two or three days. This will also help keep the bird food fresher.
