Nesting of Audubon's Warbler.

 eggs of Audubon's Warbler, (Dendroica audii-

 deep. The eggs measure on an average 18-32 

 X 23-32 inches, and the ground color is light 



blue, dotted thickly around near the middle,

 with small spots of same color. The eggs

 leave no doubts as to the identification of the
