NESTING OF THE WHITE-BELLIED NUTHATCH IN NEWTON. 



On May 27, as I was going home at night, I found a young white- 

 bellied nuthatch sitting on a fence, and I caught him in my hand. As soon 

 as I let him go he flew about twenty feet and began to climb up an apple 

 tree. On May 30, I got the lining of the nuthatch's nest. I found the 

 hole was six inches deep, and the lining was made of feathers, inner bark 

 of trees, string, and a kind of wool.

Birds are now migrating southward by millions, and the question nat- 

 urally arises as the source of this vast movement southward. There are 

 several theories in regard to this, and those who wish for information upon 

 the subject will do well to consult Gatke's "Heligoland," various articles 

 in the "Auk," an Ornithological Magazine published in New York, and 

 Maynard's "Contribution to Science," Vol. III.
