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 live 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. 



DIFFERENTIAL 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
