THE SONG SPARROW. 821 
constructed of fine twigs and roots and grasses, and is almost 
invariably lined with horsehairs; hence its name, in some 
localities, of ‘ Hair-bird,” “‘ Hair Sparrow.” The eggs are 
usually five in number. Their color is a bluish-green ; and 
they are marked with spots and lines:of black and obscure- 
brown, which are thickest at the great end: some specimens 
have these spots confluent into a sort of ring. The dimen- 
sions vary from .74 by .50 to .70 by .48 inch. This species 
is the most often chosen by the parasitic Cow-bird as a parent 
for its young; and many ornithologists account by this fact 
for its persistent familiarity with man. 
About the middle of October, the old and young birds 
gather into small flocks, and proceed leisurely on the south-_ 
ern migration. 
MELOSPIZA, Batrp. 
Body stout; bill conical, very obsoletely notched or smooth, somewhat com- 
pressed; lower mandible not so deep as the upper; commissure nearly straight; gonys 
a little curved; feet stout, not stretching beyond the tail; tarsus a little longer 
than the middle toe; outer toe a little longer than the inner, its claw not quite 
reaching to the base of the middle one; hind toe appreciably longer than the middle 
one; wings quite short and rounded, scarcely reaching beyond the base of the tail; 
the tertials considerably longer than the secondaries; the quills considerably gradu- 
ated; the fourth longest; the first not longer than the tertials, and almost the short- 
est of the primaries; tail moderately long, and considerably graduated; the feathers 
oval at the tips; crown and back similar in color and streaked; beneath thickly 
streaked; tail immaculate. 
This genus differs from Zonotrichia in shorter, more graduated tail, rather longer 
hind toe, much more rounded wing, which is shorter; the tertiaries longer; the first 
quill almost the shortest, and not longer than the tertials. The under parts are 
spotted; the crown streaked and like the back.
