spiZELLA monticola: tree sparrow. 265 



remainder simply retreated to the deepest recesses of 

 the shrubbery, where, protected from the biting winds, 

 if not from the cold, they passed the winter, and to 

 all appearances very comfortably. I account for their 

 remaining at this inclement season, by the profusion 

 of seeds of various kinds that are to be obtained during 

 the whole winter; certainly, those that I shot were in 

 good condition, and generally had the crop well filled. 

 Their seclusion and quietness at this season is remark- 

 able, and causes them to be in a great measure over-

 seen together, busily feeding. Some, more energetic, 

 spring up and cling to the swaying panicles, picking 

 away, while others gather about the stem, getting a 

 good dinner, without trouble, off" the seeds that their
