Birds of Oregon and Washington 117 



THE LUTESCENT WARBLER. 



GENERAL DESCRIPTION : 



Upper parts : light olive-green. 



Under parts : bright greenish-yellow. 



Length, 5 inches. 

 Found in trees of thick foliage. 



While listening to and searching for the Yel- 

 low Warbler, we shall hear another and oft -re- 

 peated song in the same trees ; and if we are not 

 careful, when we see its author, we shall confuse 

 it with the female of the Yellow Warbler. It is of 

 nearly the same size as that bird, a little small- 

 er. It is yellow, too, but of a darker olive-green- 

 ish tint throughout, and his song is not to be 

 mistaken, once it is recognized. The bird hides 

 more persistently in the foliage than the Yellow 

 Warbler, and will be more difficult to catch under 

 the opera-glass. But he may be found visiting 

 the leaves of apple or other fruit trees, for fare 

 for himself and young, and may then be particu- 

 larly observed. Arrives in first part of April. 



PARTICULAR DESCRIPTION. As in general descrip- 

 tion, also an " obscure crown-patch of orange-brown." 

 (Keeler.) 



Female : Duller color. 



Summer resident.
