The longspurs, genus Calcarius, are a group of birds in the family Calcariidae.

The name refers to the long claw on the hind toe of each foot.

The genus Calcarius was introduced in 1802 by the German naturalist Johann Matthäus Bechstein to accommodate a single species, Fringilla lapponica Linnaeus 1758, which therefore becomes the type species by monotypy.

[4] These are chunky ground-feeding birds with long wings which are usually seen in open areas.

Males declare ownership of a territory by singing during short flights over it.
