The Smith's longspur (Calcarius pictus) is a small ground-feeding bird from the family Calcariidae, which also contains the longspurs. This bird breeds in open grassy areas near the tree line in northern Canada and Alaska. The female lays three to five eggs in a grass cup nest on the ground. These birds nest in small colonies; males do not defend territory. Both males and females may have more than one mate. The parents, one female and possibly more than one male, feed the young birds.
