BLUEBIRD. 



Sialia sialis. 



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,
