13. Euspiza townsendi. Pa., 10282. (Type.)
From what is now known, we gather that it occurs throughout the eastern portions of North America, from the Southern States, in which it passes the
wintry months, to high northern latitudes, where some find their way in the breeding-season, extending as far to the west at least as the Missouri River region.
Three specimens were obtained at Fort Simpson, by Mr. Kennicott, in September, which indicates their probable summer presence in latitude 55°, and their near approach to the Pacific coast at the extreme northwestern portion of their distribution. Audubon also met with them in Newfoundland and in Labrador. They are known to breed as far to the south as Pennsylvania. They have been taken in the eastern portion of Nebraska, and breed in considerable numbers in Southern Wisconsin. Further investigations in regard to its distribution will probably show it to be a much more widely distributed as well as a more abundant bird than has been generally supposed.
Mr. Ridgway writes me that this bird winters in Southern Illinois, and remains there very late in the spring, but he thinks that none remain to breed.
Wilson states that it arrives in Pennsylvania early in April, where it frequents low grounds and river-courses, rears two and sometimes three broods in a season, and returns to the South as the cold weather commences. During the winter, he met with them in large numbers in the immense cypress swamps and extensive grassy flats of the Southern States, along the numerous rivers and rice plantations. These places abounded with their favorite seeds and other means of sustenance, and appeared to be their general places of resort at this season. From the river Trent, in North Carolina, to the Savannah River, and even farther south, Wilson found this species very numerous. They were not found in flocks, but skulked among the reeds and grass, were shy and timorous, and seemed more attached to the water than any others of this family. In April large numbers pass through Pennsylvania northward. Only a few remain behind, and these frequent the swamps and the reedy borders of creeks and rivers. He found their nests built in the ground, in tussocks of rank grass, surrounded by water, with four eggs of a dirty-white ground, spotted with rufous. He has found them feeding their young as late as the 15th of August. Their food seemed to be principally grass-seeds, wild oats, and insects. He supposed them to have no song, and that their only note was a single cheep uttered in a somewhat hoarse tone. They flirt their tails as they fly, seldom or never take to trees, but run and skulk from one low bush to another.
Except in regard to their song, Wilson’s account of their habits, so far as it goes, is quite accurate, although this bird really does have quite a respectable song, and one that improves as the season advances. At first it is only a succession or repetition of a few monotonous trilling notes, which might easily be mistaken for the song of the Field Sparrow, or even confounded with the feebler chant of the socialis, although not so varied as the former, and is much more sprightly and pleasing than the other. Still later its music improves, and more effort is made. Like the Song Sparrow, it
mounts some low twig, expands its tail-feathers, and gives forth a very sprightly trill that echoes through the swampy thicket with an effect which, once noticed and identified with the performer, is not likely to be ever mistaken. Nuttall calls this song loud, sweet, and plaintive. It is to my ear more sprightly than pathetic, and has a peculiarly ventriloquistic effect, as if the performer were at a much greater distance than he really is.
Their food, when they first arrive, and that which they feed to their young, consists very largely of insects, principally coleopterous ones, with such few seeds as they can glean. After the breeding-season, when their young can take care of themselves, they eat almost exclusively the ripened seeds of the coarse water grasses and sedges. They are very devoted to their young, and often display great solicitude for their safety, even when able to take care of themselves, and often expose themselves to dangers they carefully avoid at other times, and are thus more easily procured. At all other times they are difficult to shoot, running, as they do, through the grass and tangled thickets, and rarely rising on the wing. They dive from thicket to thicket with great rapidity, and even when wounded have a wonderful power of running and hiding themselves.
