This beautiful bird seems to 

 be much less frequent in its 

 winter visits to New England 

 than the preceding. It has all 

 the general characteristics of 

 that bird.. In May, in the Hud- 

 son's Bay country, according 

 to Mr. Hutchins, it builds its 

 nest in a pine-tree. This is 

 constructed of grass, mud, and 

 feathers, and is lined with moss 

 and other soft materials. The 

 female lays five white eggs, 

 marked with yellowish spots.
