EGGS: 



The complement of eggs is four or five. They are pure, pearly white, with a fine polish, and 

 measure from .90 to 1.00 in long-diameter, by from .70 to .78 in short-diameter. A common size is about 

 .72 x .95. Maynard gives the dimensions as follows: "1.04 x .80 to .95 x .75." "North American Birds" 

 says: "The eggs vary from an oblong to a somewhat rounded oval shape, are of a bright crystalline 

 whiteness, and their measurements average 1.02 inches in length by .88 of an inch in breadth." 



DIFFERENTIAL POINTS: 



The eggs of the five Woodpeckers known to be summer residents differ from each other only in 

 size and shape. All are pure white, and almost all have highly polished, pearly shells. The largest are 

 the eggs of the Golden- winged Woodpeckei', the smallest those of the Downy Woodpecker. In the 

 following list they occur according to their size: 



C. auratus — long-diameter, .93 to 1.19; short-diameter, .79 to .90. 



M. erythrocephalus— " .90 to 1.10; " .70 to .85. 



C. carolinus— " .90 to 1.00; " .70 to .78. 



p. villosus— " .87 to 1.05; " .68 to .75. 



P. pubescens— " .78 to .88; " .57 to .67. 



The Pileatecl Woodpecker is possibly a summer resident in certain sections of the State, but I have 

 been unable to obtain an undoubted record of its occurrence. 



It will be seen from the above dimensions that it is not possible to differentiate eggs of the first 

 four species with any degree of certainty unless a large number of specimens are considered. 



REMARKS : 



Fig. 2, Plate LXIV, represents three eggs of the Red-bellied Woodpecker of the common sizes and 

 shapes. They were selected for me from a number of sets in the possession of Mr. F. T. Jenks, of 

 Providence, Pt, I. 



I frequently see this handsome Woodpecker along the country roads in Central Ohio, but never in 

 the nesting season. It is always alone, and usually not very wild. I hope yet to be able to find its 

 nest in Pickaway County, and thus add one more of the family to my local list.
