Their clear and piercing whistle, "_Spring o' the y-e-a-r, Spring o' the year!_" rings out from the trees with varying intonation and accent, but always sweet and inspiriting. To the bird's high vantage ground you may not follow, for no longer having the protection of the high grass, it has become wary and flies away as you approach, calling out _peent-peent_ and nervously flitting its tail (again showing the white feather), when it rests a moment on the pasture fence-rail.
It is like looking for a needle in a haystack to try to find a meadowlark's nest, an unpretentious structure of dried grasses partly arched over and hidden in a clump of high timothy, flat upon the ground. But what havoc snakes and field-mice play with the white-speckled eggs and helpless fledglings! The care of rearing two or three broods in a season and the change of plumage to duller winter tints seem to exhaust the high spirits of the sweet whistler. For a time he is silent, but partly regains his vocal powers in the autumn, when, with large flocks of his own kind, he resorts to marshy feeding grounds. In the winter he chooses for companions the horned larks, that walk along the shore, or the snow buntings and sparrows of the inland pastures, and will even include the denizens of the barn-yard when hunger drives him close to the haunts of men.
The Western Meadowlark or Prairie Lark (_Sturnella magna neglecta_), which many ornithologists consider a different species from the foregoing, is distinguished chiefly by its lighter, more grayish-brown plumage, by its yellow cheeks, and more especially by its richer, fuller song. In his "Birds of Manitoba," Mr. Ernest E. Thompson says of this meadowlark: "In richness of voice and modulation it equals or excels both wood thrush and nightingale, and in the beauty of its articulation it has no superior in the whole world of feathered choristers with which I am acquainted."
_Length_--7.5 to 8 inches. About one-fifth smaller than the robin.
_Male_--Upper parts dull brown, streaked with lighter on edges and tinged with pink or vinaceous; darkest on back of head, neck, shoulders, and nearest the tail. A few erectile feathers on either side of the head form slight tufts or horns that are wanting in female. A black mark from the base of the bill passes below the eye and ends in a horn-shaped curve on cheeks, which are yellow. Throat clear yellow. Breast has crescent-shaped black patch. Underneath soiled white, with dusky spots on lower breast. Tail black, the outer feathers margined with white, noticed in flight.
