72 IN BERKSHIRE FIELDS 



writers say they excavate these holes for them- 

 selves, but I have never seen a nest in a hole which 

 didn't appear to have been already dug. The act- 

 ual nest is made of wood fiber, wool, hair, fine 

 moss, feathers, or other soft material. They take, 

 the hair where they can get it. Thoreau, who loved 

 the chickadees and used to watch them pecking

 hand in the Concord woods, records a nest in a small

 differ in appearance, so it is usually impossible 

 to determine which is the mother, except in the

 is the song that tinkling little lisp with which it 

 talks to you from the low twigs of an apple-tree as 

 you pass by. Its song is the exquisitely clear whistle 

 which is most commonly heard in spring, and which
