 were not found. Specimens of this species may invarial)ly — as far

 greater intensity of yellow on the former, as well as by the quill 

 characters."

This charming little bird is abundant in all cultivated portions of 

 the countiy, and even where the population is sparse and the 

 forests extensive, it is more or less common along the margins of 

 streams and edges of the woods. It is particnbirly numerous among 

 the large silver-maples and associate trees which droop their grace- 

 ful foliage over the banks of the larger streams, while in all towns 

 having abundance of shade trees along the streets it is one of the 

 commoner and more familiar species.

 Brewer, who gives the following pleasing account of it in History of
