Sky"lark`, n. (Zoöl.)
Definition: A lark that mounts and sings as it files, especially the common
species (Alauda arvensis) found in Europe and in some parts of Asia,
and celebrated for its melodious song; -- called also sky laverock.
See under Lark.
Note: The Australian skylark (Cincloramphus cantillans) is a pipit
which has the habit of ascending perpendicularly like a skylark, but
it lacks the song of a true lark. The Missouri skylark is a pipit
(Anthus Spraguei) of the Western United States, resembling the
skylark in habit and song.
