ABOUT:
The commonest tit in the British Isles, a bird of woodland, parks and gardens that nests in tree holes, but is just as happy to use nestboxes. Blue tits are active feeders, hunting out insects and spiders among the smaller branches and leaves of trees in woodlands. They have a small compact crown, which is raised when the bird is excited or angry. In winter, they will form flocks with other tits, roaming the countryside and visiting gardens in groups.
DID YOU KNOW?
Like most birds, blue tits can see ultra-violet (UV) light. Studies have shown that the blue crown on their heads glows brightly under UV light. The brightness of the feathers is thought to provide a variety of signals; for instance, male blue tits have been shown to choose females with brightly coloured crowns as they make fitter mothers.
