A sparrow-sized (6 ½ inches) songbird, the Lapland Longspur is among the most striking birds in much of its range. Breeding males may be identified by their black face and bib, yellowish-orange bill, reddish-brown collar, white eye-stripe, and white tail-edges. Females have similarly-patterned plumage but are duller and more streaked. Both sexes are much duller in their winter plumages than they are in summer. The Lapland Longspur is found widely across the Northern Hemisphere, and is the only longspur to occur outside of North America. In North America, this species breeds across the high arctic from Alaska east to Greenland and south to the Hudson Bay. In winter, Lapland Longspurs may be found in the greatest numbers on the Great Plains south of the Canadian border, with smaller numbers in the northeast and along the Pacific coast. In the Old World, this species breeds in Scandinavia and Russia, wintering as far south as Britain, Central Asia, and East Asia. Lapland Longspurs breed on tundra, particularly in areas that are wet or well vegetated. In winter, this species inhabits a number of open habitat types, including grasslands, fields, and lakeshores. Lapland Longspurs primarily eat seeds, but may eat insects and other invertebrates when available, especially during the breeding season. Due to its remote breeding habitat, most birdwatchers never see Lapland Longspurs during the summer. In winter, this species may be observed in large flocks foraging for food on grasslands or fields. Longspurs may be seen walking or running on the ground as well as in the air flying between feeding areas. This species is primarily active during the day.

The Lapland longspur (Calcarius lapponicus), also known as the Lapland bunting, is a passerine bird in the longspur family Calcariidae, a group separated by most modern authors from the Fringillidae (Old World finches).
The English name refers to the long hind claws.[2] The genus name Calcarius is from Latin calcaria, "spurs", and the specific lapponicus refers to Lapland.[3]
The Lapland longspur is a robust bird, with a thick yellow seed-eater's bill. The summer male has a black head and throat, white eyestripe, chestnut nape, white underparts, and a heavily streaked black-grey back. Other plumages have a plainer orange-brown head, a browner back and chestnut nape and wing panels.
Measurements:[4]
It breeds across Arctic Europe and the Palearctic and in Canada and the northernmost United States. It is migratory, wintering in the Russian steppes, the southern United States, Northern Scandinavian arctic areas and down to coastal Southern Sweden, Denmark and Great Britain. This is the only Asian species of the longspur buntings, and while it probably did not evolve there, it has been present in Eastern Europe for at least about 30,000 years.[5]
The most common flight call is a hard "prrrrt" usually preceded by a more nasal "teeww". When breeding, it also makes a softer "duyyeee" followed by a pause and a "triiiuuu"; both sounds alternate.
It breeds in wet areas with birch or willow, and or bare mountains, and winters on cultivated land or coasts. The bird is often seen close to the tree line, and likes to feed in mixed-species flocks in winter. Its natural food consists of insects when feeding young, and otherwise seeds. The nest is on the ground. 2–4 eggs are laid.
The food habits of the Lapland longspur are quite simple: mostly seeds in winter and arthropods in the summer, when they are in activity.[6]
During the winter, the longspur feeds on seeds. They pick them on the ground, rarely feeding directly on plants. They will forage around the same area for a period varying between a few minutes and an hour, then fly away looking for a new foraging area. Their seed diet is composed mainly of seeds from grass, foxtail, cultivated millet, crabgrass and wheat.[6] During the breeding season, the birds migrate to the north, where their diet switches to arthropods. Nestlings are only fed arthropods, which also constitute the diet of the parents at that time of the year (June to July). The birds often catch insects in mid-air, but do forage through vegetation when climatic conditions prevent the insects from flying.[7] Longspurs can consume between 3000 and 10,000 prey items (insects or seeds) per day, depending on their energy needs ; they may need to increase this number by 3000 when feeding the young.[8] Dipteran larvae and adults form the major part of their insectivorous diet.[9]
