Blue Tits are very active feeders, naturally flitting among small branches of woodland trees looking for insects and spiders. When nesting they feed mostly caterpillars to their young. They are one of the most welcome and frequent visitors to garden bird feeders, especially for peanuts but also seeds and fat balls.

Like Coal Tits and Great Tits, Blue Tits love to eat insects, seeds and nuts. However, they have a particular penchant for the caterpillars of the winter moth and will fly far and wide to find them.
