Incubation, which is attended to by the female, usually begins as soon as the complement of eggs 

 is complete, and continues about twelve days. 



, The color of the eggs is a delicate blue, possibly sometimes spotted. They measure from .95 x 

 .65 to l.lOx.80; average of forty specimens, 1.00 x .70. 



DIFFEREJ^TIAL POmTS: 



The only nest built in Ohio, with which that of the Wood Thrush is apt to be confounded, if 

 any attention at all is paid to construction, is that of the Robin, and from this it can easily be dis- 

 tinguished by the fact that the latter is lined with dried grasses. The eggs may be confounded with 

 those of the Cat Bird and Robin ; from the former they can generally be distinguished by the color, 

 from the latter by their size. However, with some specimens, it is impossible to say whether they are 

 large eggs of the Wood Thrush or small eggs of the Robin. In such cases of doubt, of course, the 

 question can be determined at once if the nest is at hand. 



REMARKS : 



Though the Wood Thrush is naturally shy, she rarely abandons her nest on account of intrusion ; 

 being repeiitedly driven from it, she as often Teturns as soon as the danger is past. Cow Buntings often 

 leave their eggs in her care; on several occasion's as many as three have been taken from under one 

 bird. The same home is often occupied for a series of years, the annual repairs consisting either of a 

 new plastering and lining, or the latter alone. One nest in the authors' collection shows four distinct 

 yearly additions. The first three seem to have been perfect structures, the fourth consists only of an 

 abundance of rootlets, making a thick lining to the nest of the previous summer. The whole was stoutly 

 placed in a perpendicular fork, which enabled it to resist so well the wear and tear of the seasons. 



The plate represents a nest of the average size, and materials of construction, as they occur in 

 Central Ohio. It Wcis taken on the 30th of May, 1877, from a haw tree, Cratcegus spatlmlata, in a damp 

 wood without much undergrowth. The light fluffy leaves of the foundation, the mossy branches and 

 emerald foliage, the boggy earth and rank givass beneath, together formed a picture beautiful and rustic, 

 a fitting symbol of the quiet wood, the drear repose in which this brilliant songster so much delights.
