RUBY-CROWNED KINGLET. 
749. Regulus calendula. 4% inches. 
Male with a concealed patch of red on the crown; fe- 
male 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 .48). 
Range.—N. A., breeding northward from the north- 
ern boundary of the U. S. and farther south in moun- 
tains: winters in the southern half of the U.S.
