LARKS
        Family Alaudidae
        LARKS

          LMOST EXCLUSIVELY GROUND birds, except
        Awhen singing, larks are quite stocky but
        long-bodied birds, bulkier than pipits or wagtails,
        but less chunky than most finches.They have
        thick, triangular bills – between the insect-eating
        bill of a pipit and the seed-eating bill of a finch,
        reflecting their varied diet.They fly strongly,with
        quite long, often rather angular wings.
         Larks have faintly short legs but long toes and
        claws, especially the claws on their hind toes,
        which seem to be an adaptation for walking
        through grassy vegetation.They move easily

        on open ground: the Skylark, for example, will  flight but their more angular wings have a straighter rear edge.

        sings for minutes on end in a simple rising hover,
        while the Woodlark flies in wide circles as it sings.
         Plumages of males and females, winter and
        summer, are usually much alike, although some
        juveniles are sufficiently different to look unusual.
        Some species are very difficult to identify: calls
