The Willow tit is a widespread and common resident breeder throughout temperate and subarctic Europe and northern Asia. Look for them from wet woodland and willow carr growing in wetlands, bogs and around gravel pits. Willow tits eat mostly insects, but will also eat berries and seeds when food is scarce in the winter. They use their small bills to excavate nest holes in decaying wood, which is unusual among the tit family. Did you know that Willow tit is so similar to the Marsh tit, that they where not recognized as a separate species until 1897.
