   Any one numerous species of singing birds of the genus
   {Alauda} and allied genera (family {Alaudid[ae]}). They
   mostly belong to Europe, Asia, and Northern Africa. In

   the shore larks, or horned larks, of the genus {Otocoris}.
   The true larks have holaspidean tarsi, very long hind claws,

   Note: The European skylark, or lark of the poets ({Alauda
         arvensis}), is of a brown mottled color, and is noted
         for its clear and sweet song, uttered as it rises and
         descends almost perpendicularly in the air. It is
         considered a table delicacy, and immense numbers are
         killed for the markets. Other well-known European
         species are the crested, or tufted, lark ({Alauda
         cristata}), and the wood lark ({A. arborea}). The
         pipits, or titlarks, of the genus {Anthus} (family
         {Motacillid[ae]}) are often called larks. See {Pipit}.
         The American meadow larks, of the genus {Sturnella},
         are allied to the starlings. See {Meadow Lark}. The
         Australian bush lark is {Mirafra Horsfieldii}. See
         {Shore lark}.
