RUBY-CROWNED KINGLET. 



749. Regulus calendula. 4^4 inches. 



Male with a concealed patch of red on the crown; 

 female with no red. 



Like the last, these are chiefly winter visitants 

 in the United States, and they do not remain with 

 us in the coldest weather but pass on to the southern 

 half of our country. They are nearly always met 

 with in pine or other coniferous trees, being very 

 abundant in spring in open pine woods and parks. 



Song. A clear warble, surprisingly loud and varied 

 for so small a bird; call a grating chatter. 



Nest. A ball of moss, grass and feathers, deeply 

 cupped like that of the last; partially suspended 

 among the small twigs in the tops of coniferous 

 trees; eggs white more sparingly marked than those 

 of the last (.55 x .43). 



Range. N. A., breeding northward from the north- 

 ern boundary of the U. S. and farther south in 

 mountains; winters in the southern half of the U. S.
