BIRDS OF PENNSYLVANIA 
The eggs, small at one end and quite pointed, measure about 1.50 
inches long by about 1.08 broad. 
“The food of this species consists of earth-worms, grasshoppers, 
crickets and coleopterous insects, as well as small Crustacea, whether of 
salt or fresh water, and snails. Now and then they may be seen thrust¬ 
ing their bills into the mud in search of some other food. During 
autumn they run about the old fields and catch an insect which the blue¬ 
bird has been watching with anxious care from the top of a withering 
mullein stalk. They run briskly after the plowman to pick up the 
worms that have been turned out of their burrows. Now standing on the 
grassy meadow, after a shower, you see them patting the moist ground, 
to force out its inhabitants. During winter you meet with them on 
elevated ground, or along the margins of the rivers ; but wherever you 
observe one about to pick up its food you clearly see its body moving in 
a see-saw manner on the joints of the legs, until the former being so 
placed that the bill can reach the ground, the object is seized, and the 
usual horizontal position is resumed.”— Audubon.
