Pipit \Pip"it\, n. [So named from its call note.] (Zo["o]l.)
   Any one of numerous species of small singing birds belonging
   to {Anthus} and allied genera, of the family
   {Motacillid[ae]}. They strongly resemble the true larks in
   habits, colors, and the great length of the hind claw. They
   are, therefore, often called {titlarks}, and {pipit larks}.

   Note: The {meadow pipit} ({Anthus pratensis}); the {tree
         pipit}, or tree lark ({A. trivialis}); and the {rock
         pipit}, or sea lark ({A. obscurus}) are well-known
         European species. The common American pipit, or brown
         lark, is {Anthus Pensilvanicus}. The Western species
         ({A. Spraguei}) is called the {American skylark}, on
         account of its musical powers.

Titlark \Tit"lark`\, n. [Tit a small bird + lark.] (Zo["o]l.)
   Any one of numerous small spring birds belonging to {Anthus},
   {Corydalla}, and allied genera, which resemble the true larks
   in color and in having a very long hind claw; especially, the
   European meadow pipit ({Anthus pratensis}).
