BIRDS OF PENNSYLVANIA .

These birds would remain about two weeks, or until the wheat had 
sprouted. They subsisted almost exclusively on wheat. My informant 
states that prior to 1860, for at least fifteen years, these birds annually, 
in the fall, made these visits, and that he had always been told, when a 
boy, that “Bull-heads” were abundant every year. 
Audubon furnishes the following* information of this species: “While 
searching for food on the sand or mud bars of the seashore they move 
in a direct manner, often look sideways toward the ground, and pick up 
the object of their search by a peculiar bending movement of the body. 
They are frequently observed to pat the moist earth with their feet to 
force worms from their burrows. In autumn they betake themselves to 
the higher grounds, where berries as well as insects are to be met with, 
and where they find abundance of grasshoppers.” 
Five of these plovers taken in September and October, 1880, in Ches¬ 
ter county, had fed chiefly on grasshoppers and beetles; one had in its 
stomach a few small brownish seeds, with several large beetles, and an¬ 
other had its stomach gorged with grasshoppers with which were a few 
small black-colored worms.

Reader, I am sure you can always distinguish this bird by the well- 
known cry which gives rise to its common name. Should you, however, 
have the lifeless body of one of these birds, you can without any diffi¬ 
culty distinguish it from other of its numerous relatives by the red eye¬ 
lids and long legs. In addition you will also see a white line, with 
black margin, extending over the bill, between the eyes. The white 
feathers of the throat are continuous, with a conspicuous and immacu¬ 
late collar, below which is a ring of black, separated by a streak of white 
from a band of black across the breast. 
During the spring, summer and autumn the Kildeer is common in 
nearly all parts of Pennsylvania, and in winter it is quite frequently 
observed, particularly in the southern parts of the state. The spotted 
pyriform eggs, usually four in number, are plaoed in a slight hollow in 
the ground, oftentimes near a hill of corn.
