THE TREE SPARROW. 317 
“In some parts of New England, I found the opinion pretty 
general, that the Snowbird, in summer, is transformed into the 
Small Chipping Sparrow, which we find so common in that season. 
I had convinced a gentleman of New York of his mistake in this 
matter, by taking him to the house of a Mr. Gautier there, who 
amuses himself by keeping a great number of native as well as 
foreign birds. This was in the month of July; and the Snow- 
bird appeared then in the same colored plumage he usually has. 
Several individuals of the Chipping Sparrow were also in the same 
apartment. ‘The evidence was, therefore, irresistible; but, as I 
had not the same proofs to offer to the eye in New England, I had 
not the same success. . 
“There must be something in the temperature of the blood or 
constitution of this bird, which unfits it for residing, during sum- 
mer, in the lower parts of the United States, as the country here 
abounds with a great variety of food, of which, during its stay, it 
appears to be remarkably fond. Or perhaps its habit of associating 
in such numbers to breed, and building its nest with so little pre- 
caution, may, to insure its safety, require a solitary region, far from 
the intruding footsteps of man.”
