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.
Mr. Audubon met with them, during autumn and winter, among the flat sand-bars of the Mississippi, which are overgrown with rank grasses. Though not in flocks, their numbers were immense. They fed on grass-seeds and insects, often wading for the latter in shallow water in the manner of the Tringidæ, and when wounded and forced into the water swimming off to the nearest shelter. He also met with these birds abundantly dispersed in the swamps of Cuyaga Lake, as well as among those along the Illinois River in the summer, and in the winter up the Arkansas River.
Mr. Townsend observed these birds on the head-waters of the Upper Missouri, but did not meet with them beyond.
In Maine, Mr. Boardman gives it as a regular summer visitant at Calais, arriving there as early as March, becoming common in May, and breeding in that locality. Professor Verrill found it in Western Maine, a summer visitant and breeding, but did not regard it as common. From my own experience, in the neighborhood of Boston, I should have said the same as to its infrequency in Eastern Massachusetts, yet in certain localities it is a very abundant summer resident. Mr. William Brewster has found it breeding in large numbers in the marshes of Fresh Pond, where it arrives sometimes as early as the latter part of March, and where it remains until November. In the western part of the State it is more common as a migratory bird, and has not been found, in any numbers, stopping to breed. Mr. Allen never met with any later than May 25. They were observed to be in company with the Water Thrush, and to be in every way as aquatic in their habits. In the autumn he again met with it from the last of September through October, always in bushy marshes or wet places. Mr. McIlwraith states that in the vicinity of Hamilton, Ontario, it is a common summer resident, breeding there in marshy situations. At Lake Koskonong, in Wisconsin, Mr. Kumlien has also met with these birds abundantly in suitable localities, and found their nests and eggs quite plentiful.
Mr. Ridgway has recently found this Sparrow to be a very abundant winter resident in Southern Illinois, where it inhabits swampy thickets, and where it remains until May, but is not known to breed there.
They always nest on the ground, usually in a depression sheltered by a tuft of grass. The nest is woven of fine grass-stems, but is smaller than the nest of M. melodia.
The eggs of this species, usually five in number, have an average measurement of .78 by .60 of an inch. Their ground-color is usually a light green, occasionally of a light clay, marked and blotched with reddish and purplish brown spots, varying in size and number, occasionally forming a confluent ring around the larger end.

Legs and feet with the claws small; the tarsus about equal to the middle toe; the lateral toes equal, their claws falling considerably short of the middle one; the hind toe reaching about to the middle of the latter. The outstretched feet reach rather beyond the middle of the tail. The wing is very short, reaching only to the base of the tail; the longest tertials do not exceed the secondaries, while both are not much short of the primaries; the outer three or four quills are graduated. The tail is considerably longer than the wings; it is much graduated laterally; the feathers, though long, are peculiarly narrow, linear, and elliptically rounded at the ends.
