Measurements. — Length to in.; spread to ; folded wing to ; tail to ; bill .32 to .40; tarsus .65 to .74. Female smaller than male. Molts. — Juvenal plumage acquired by complete postnatal molt in the fledgling; first winter plumage by postjuvenal molt (September) involving body plumage and wing-coverts and not usually flight-feathers or tail, but one specimen examined was molting both; first breeding plumage by wear; adults have one complete postnuptial molt (August, September) and acquire breeding plumage by wear. Field Marks. — Size near Chipping Spar- row ; bill pinkish; tail slightly forked. Adults and young in first winter plumage: Much like Tree Sparrow, but wing-bars not so white, and head, throat and breast more brown than gray; lacks the dark spot on breast seen on Tree Spar- row, and has no black and white stripes on side of head such as Chipping Sparrow shows. Young in juvenal plumage: Somewhat Like young Chipping Sparrows, but not so distinctly streaked on cap and breast. Voice. — Call note, a tsip not so hard and sharp as that of Chipping Sparrow; song, a pensive strain, often varied; usually begins with a few slow, high, clear, prolonged slurred notes, then accelerates, and finally trails off diminuendo in rapid repetitions, fading as its ends; some songs are all on the same note, others rise or fall; W. L. Dawson expresses a common rendition thus, he-ew, he-ew, he-ew, he-ew, hew, hew, hew, he heeeeu. Breeding. — In open, bushy, old fields and berry pastures chiefly, or in undergrowth near borders of woods. Nest: In low bush such as a huckleberry, in a brier patch or on ground, rarely 5 to 10 feet from ground in tr
