Lark behaviour
These pretty little birds are usually seen in small, scattered parties, though in winter they may congregate in larger flocks, often in company with other species, such as Snowflakes, Longspurs, etc. They run along the ground in front of a pedestrian, but if pressed too closely, rise with a sharp whistled note and after circling around alight usually at no great distance and resume their feeding. During the breeding season they have a very pretty though short song, which is usually uttered while, with tail expanded, the bird is soaring in the air, but it is also given while they are perched on a low stone or clod of earth. They begin nesting early in the season, often while there is still snow on the ground, usually choosing the benches of the prairies or higher ground, where they place the slight nest of dried grasses in a shallow depression by the side of a tuft of grass, a stone, or other object. Both parents take part in incubation and are very solicitous for eggs and young, often trying to lead an intruder away. The eggs are usually three or four in number and are olive-buff thickly specked and spotted with brownish and dark lavender. Two and sometimes three broods are reared in a season by certain of the forms.
Without attempting to distinguish between the obscurer forms, it may be mentioned that the common Horned Lark of North America (O. alpestris) is of large size, being between seven and a half and eight inches in length, and has the upper parts dark, the throat and eyebrow sulphur-yellow, and a large patch of yellow on the side of the head and upper breast. This bird is found in summer in Newfoundland, Labrador, and the Hudson Bay region, coming south in winter into the eastern United States. Considerably smaller than this, and with the nape, rump, and bend of the wing more pinkish, is the Old World form (O. a. flava) which summers in the extreme northern part of Norway and Sweden, northern Russia, and Siberia, while in winter it visits the British Isles and central and southern Europe. The other commonest American forms are the Pallid-horned Lark (0. a. leucolcema) and the Prairie Horned Lark (O. a. praticola).
