Above azure-blue; throat and upper-breast cinnamon; belly dull 
white ; eyes large; tail and wings broad, the former slightly notched ; 
bill and legs black. Length, 7 inches. 
A migratory species; individuals, probably those with the northernmost range, being 
usually present with us through the Winter. 
Arrives early in March or even in February, leaves late in November. Song a soft, 
pleasing warble in which a resemblance to the syllables ¢ru-a/-ly often repeated has been 
noticed. The bird utters this song when he ts flying and when he is at rest. 
Nests in holes of trees or posts, or in boxes placed for his use in gardens. 
One of the earliest comers, the Bluebird is gladly welcomed as a harbinger of Spring, 
and his arrival is more widely remarked than that of most of the other birds. As the 
season advances and the tide of migration sets fully in. he loses his prominence. until, in 
Fall, many of the Summer visitors having departed, he again assumes importance ;
