What is "anthus spraguei"

Skylark \Sky"lark`\, n. (Zo["o]l.) 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.

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