Open Nests on the Ground 
Breeding Range—The Eastern States, from Virginia to Massachu- 
setts, ‘‘ westward to the edge of the plains.” 
The nest is somewhat roughly built of coarse grass, placed 
on the ground often in a slight depression, or close against a 
tussock in the open fields. The eggs, 3 to 5 in number, are 
white or nearly white, with distinct brown and purplish spots, 
more numerous at the larger end. Size—.73 x .56. 
This shy and unobtrusive sparrow is rather difficult to find, 
owing to its habit of remaining in the thick grass unless forced 
to fly. In its short, jerky flight it resembles its near relation, the 
yellow-winged or grasshopper sparrow. Generally speaking, it 
prefers the more moist fields to those that are very dry. The 
nest, as in the case of other birds of similar habits, is well and 
carefully hidden in the grass. In Illinois, eggs have been 
found as early as April 20th and as late as August 12th. Mr. 
Brewster says that this sparrow breeds commonly but very 
locally in the eastern part of Massachusetts, quite numerously in 
portions of Worcester County, sparingly and locally in Berkshire 
County.

Fig. 1, Plate B. 
The Sharp-tailed Sparrow resembles the seaside sparrow in its 
choice of locality, being found always near the salt water, choosing 
for its nesting place either the brackish or salt-water swamps, or
