BIRDS OF PENNSYLVANIA. 
they often visit the barnyards, and, if not molested, will become rather 
tame. They also, at these periods of snow inundation, assemble in the 
public highways and glean a scanty subsistence from the droppings of 
horses. Although larks frequently alight on trees, they never, I think, 
are seen to feed in such places, their food is collected from the ground. 
In spring the flocks break up and these birds are observed singly or in 
pairs. Nest building, in this latitude, is begun late in April or early in 
May. Both sexes engage in constructing their nest, composed of dried 
grasses, placed on the ground, and most ingeniously concealed in a thick 
tuft of grass. The nests are built in meadows and grass flelds, and fre- 
quently, though not always, rest in a concavity of the earth. 
The oval white eggs, usually five in number, are spotted with reddish- 
brown ; they vary considerably in size, but average about 1.16 inches 
long by .80 of an inch wide. Their food consists of various forms of in- 
sects, among which may be mentioned beetles, grasshoppers, larvae, 
earth-worms, ants, etc. The lark, like the Bed-winged Blackbird, is 
fond of “ cut-worms,” he also subsists on the seeds of various grasses, 
weeds, etc., and, according to Mr. Gentry, they sometimes feed on wild 
cherries, wild strawberries and blackberries. Although this species will 
sometimes eat the grains of wheat, oats, rye or particles of corn which 
they find scattered on the ground in fields or other places, they rarely 
disturb these cereals when growing, and never commit, in grain fields, 
any depredations at or about the season of harvest. Seventeen Meadow, 
larks, which I captured (March and April, 1885), in the open pine woods 
of Florida, were found to have fed only on insects, chiefly beetles. In 
December, 1886, I killed seven of these birds in Chester county. Pa., 
their stomachs were all gorged with grasshoppers. In the Carolinas, 
Audubon says, many planters agree in denouncing the lark as a depre- 
dator, “ alleging that it scratches up oat seeds, when sown early in spring, 
and is fond of plucking up the young corn, wheat, rye or rice.”
