pendent Usnca mosses. Interiorly, they were 

 smoothly and elegantly lined with the seed-stalks of 

 Cladonia mosses, dark fibrous roots, and a sprink-

 cavity three inches wide, and one and a quarter 

 deep. 



The eggs are oblong-oval in configuration, and 

 vary in length from .70 to .65 of an inch, and in 

 breadth from .52 to .50. They are closely marked 

 with brown upon a greenish-blue background, and 

 generally possess an annulus of brown and lilac 

 blotches around the larger end. 



We have never observed this species in the 

 autumn, from which fact we infer that it does not 

 stop during its southern migration.

 of lofty trees, in high and open woods; but as the 

 season advances, our gardens and orchards are 

 the recipients of its visits, where it delights to 

 revel amid apple and cherry blooms. Like the 

 last described species, it manifests considerable
