This lark is a bird of easy and beautiful flight, passing and repassing through the air with graceful evolutions, and when moving to new localities, sweeping over the place several times before alighting. It also moves rapidly on the ground and after the manner of the true larks, jerking the tail like our Water-Thrushes and the European Wagtails. When feeding on the open ground in the interior, their food is chiefly insects and small seeds. On the banks of rivers and on the seashore they are fond of running along the edge of the water, searching among the drift for insects, small shells, and crustaceans. Near New Orleans and Charleston, in the winter, Mr. Audubon found them feeding, in company with the Turkey Buzzard, upon garbage. Dr. Coues found the Titlark abundant in every locality visited by him in Labrador, giving him an ample opportunity to observe its habits during the breeding-season. He found them on some of the most rocky and barren islands along the coast. They frequented only the open, bare, and exposed situations, such as that coast everywhere afforded, and were never found in wooded localities. The nests of this species found by him were identical in situation, form, and construction, placed on the sides of steep, precipitous chasms, in small cavities in the earth, into which dry moss had been introduced to keep the nest from the damp ground. They were composed entirely of coarse, dry grasses loosely put together, without any lining. Their external diameter was six inches, and the depth of the cavity two inches. Dr. Coues describes the song of the male bird as very sweet and pleasant. Mr. Audubon speaks of it as consisting of a few clear and mellow notes when on the wing, and when standing erect on the rocks it produces a clearer and louder song. Dr. Coues speaks of their flight as undulating and unsteady, and never protracted to any great distance. They never alight on bushes, but always on the ground, where they run with great ease and rapidity. At low tides they resorted to the muddy flats, where they ran about upon the eel-grass, searching for their food in company with the small Sandpipers and in a similar manner, finding there an abundance of food. At all times they exhibited a heedless familiarity and an entire want of fear of man, feeding unconcernedly around the doors of the houses, and searching for their insect food on the roofs of the sheds and dwellings. Both birds incubate and sit so closely that they may almost be trodden upon before they are willing to leave their nest, and even then only flutter off to a short distance, with loud cries of distress that soon bring the mate and other pairs of the same species to join in the lamentations. They hover over the heads of the intruders, at times approaching within a few feet, expressing their distress by the most plaintive cries, and even when the intruders withdraw following them to a considerable distance.
