than other birds, while some do not warble at 

 all. But they are alike in their habits. They 

 are the birds of the trees and the leaves. They 

 live among the leaves and feed upon the insects 

 which they gather from them. Sometimes, too, 

 some of them take an insect on the wing as do 

 the Flycatchers. 



Except when upon a nest, or at night, they are 

 ever in motion, searching leaf after leaf for their 

 food. 



They are all small birds, all of them well 

 dressed, many of them exquisitely plumaged. 

 Besides the two mentioned, the following are 

 more or less common in Oregon and Washing- 

 ton, and may be quite easily identified. The 

 Yellow, Lutescent, Macgillivray's, Black-throated 

 Gray and Pileolated Warblers ; also the Long- 

 tailed Chat.
