At Cape Disappointment, Washington, Mr. Kobbe found the 

 chestnut-backed chickadees affecting preferably the more open 

 woods along roads and trails. They were very common all the year 

 around, especially during the rainy winters, when larg? flocks of 

 them could be seen scrambling about on the branches of the drip- 

 ping firs in search of insects. They were often found with Oregon 

 chickadees and golden-crowned kinglets. Their call-note Mr. 

 Kobbe gives as a lisping the-the-the-te-te.
