The largest of the UK’s tits, Great Tits are birds of woodland, parks and gardens where they nest in holes in trees but are just as happy to use nestboxes as substitutes. Tits are active feeders, hunting out insects and spiders amongst the smaller branches and leaves of trees in woodlands. But they are also well-adapted to gardens and towns and will visit birdtables, fighting off other, smaller tits to get to the food. Great Tits have a distinctive song: listen out for a high-pitched bicycle pump or ‘teacher teacher’ sound.
