Fabulous blue tit facts

  • Blue tits feed mostly on insects, especially caterpillars, and seeds. In springtime they feed also on pollen, nectar and sap, and in the autumn on berries.

  • Their average life expectancy is 1.5 years; however, the oldest known bird reached almost 10 years.

  • They do not usually wander more than a few kilometres away from where they were born.

  • Blue tits are very adaptable, and engagingly acrobatic. One of the quickest of birds to exploit a new food source, they rapidly learn to use any new feeder, and can hang upside down on almost anything.

  • Gilbert White refers to the blue tit as the 'blue titmouse' in his History of Selbourne 1789. A local name is the Tom Tit.

  • In winter blue tits form flocks with other tit species.

  • Like all birds, blue tits can see ultra-violet light - the front of their head glows brightly under UV light and this is how females are thought to choose their partners.
