 flected one. Thus the plumes of the neck of 

 Mango appear to advantage in a room with a single 

 light, only when the beholder stands with his back 

 to the window, and has the bird before him and 

 facing him. Then the perpendicular band down

I have never met with the nest of this species ;

 cotton. The sides are tightly banded round with
