The history of the Passenger Pigeon, or Wild Pigeon as it is more commonly called, as it is 
found in Ohio to-day, will consume but little space. Once it summered here in countless thousands, 
now it is only occasionally that a nest is to be seen, and the birds themselves are met with only 
in small straggling bands. About ten years ago I found a small colony nesting in a large oak woods, 
about five miles west of Circleville, but since then I have only encountered these birds in the spring 
and fall. In October, 1884, I saw a flock of about fifty birds, and in the following spring I saw two feeding- 
in a cattle-yard. 
Two broods are commonly reared by a single pair during the summer. 
LOCALITY: 
The nest is placed in a tall tree in a forest. The locality being selected chiefly with reference to 
food and water supply. 
POSITION: 
It is usually situated in a perpendicular or horizontal fork, and may be at any distance from the ground, 
from the lowest to the highest suitable branches. 
MATERIALS: 
The principal materials are sticks and straws, arranged crosswise, and interlaced so that they form 
a platform slightly concave on top. The structure is held in position by the interweaving of the sticks 
with the branches of support, or by resting upon a large limb. 
EGGS: 
The eggs are two in number, elliptical in shape, white, unmarked, and measure from 1.35 to 1.55 in 
long-diameter, by from .98 to 1.08 in short-diameter. A common size is about 1.00 x 1.50. 
DIFEERENTIAL POINTS : 
See Table. 
REMARKS : 
Fig. 5, Plate LXIV, represents three eggs of the Passenger Pigeon, of the ordinary shapes and 
sizes. It was impossible to obtain a fresh nest in position for illustrating. 
Civilization has made marked changes in the habits and numbers of the resident, migratory, and 
summer-resident birds of Ohio, but in no instance is this change more marked than in the case of the
