“At the little village of Denison, where I first noticed it in song, it was particularly common, and half domestic in its habits, preferring the streets and grassy lanes, and the immediate vicinity of the village, to the remoter prairie. Here, wholly unmolested and unsuspicious, it collected its food; and the males, from their accustomed perches on the housetops, daily warbled their wild songs for hours together.” These traits of familiarity, so totally different from anything ever observed in our eastern birds, he does not concede, however, as establishing necessarily specific difference. Yet he does admit that its song was so new to him that he did not at first have the slightest suspicion that its utterer was the western Meadow Lark, as he found it to be. He adds: “It differs from that of the Meadow Lark in the Eastern States, in the notes being louder and wilder, and at the same time more liquid, mellower, and far sweeter. They have a pensiveness and a general character remarkably in harmony with the half-dreamy wildness of the primitive prairie, as though the bird had received from its surroundings their peculiar impress. It differs, too, in the less frequency of the harsh, complaining chatter so conspicuous in the eastern bird.” The value of these marked differences, both in song and character, between the eastern and western birds, we will not argue, but will only add that they are none too strikingly presented by Mr. Allen. During the writer’s brief visit to the Plains he was strongly impressed by the natural, confiding trustfulness of this species and its wonderful beauty of song, both in such remarkable contrast with the habits of our eastern birds. At Antelope Station a pair of these birds had built their nest under the window of the office, and seemed to enjoy the society of the family, while the depot-master, familiar with the song and habits of our eastern birds, appreciated the great differences between the two forms, and called my attention to them. Mr. Allen also found this Lark everywhere abundant in Colorado, but its notes appeared to him quite different from those of the representatives of this species living to the eastward, in the prairie States, being less varied and ringing, and more guttural.
