The Tree Sparrow is a common winter resident of most 

 parts of the State. The species is almost as regular in ap- 

 pearance as the Junco, but not so plentiful. Though called 



the Tree Sparrow, it is largely a 

 ground Sparrow while in Massa- 

 chusetts. Wherever it can find a

winter, unless driven south by 

 snows so deep as to cover its food 

 supply. It frequents thickets on

 one-half natural size. swamps, meadows, or WBcdy fields. 



In such fields it often feeds far from bushy cover, but flies 

 quickly to the thicket upon the approach of danger. 



This species usually goes in flocks, and individuals are not 

 commonly seen alone ; although a single bird may some- 

 times be found with a flock of Juncos. It feeds mainly on 

 the ground, and picks up the seeds of weeds as they fall. 

 A snowfall merely brings the birds nearer the tops of the 

 weeds, and so long as there is plenty of seed they are as 

 happy as the Snowbirds. They can climb about among 

 the stronger weed stalks, clinging like a Goldfinch. Often 

 two birds may be seen feeding from a single weed, while 

 another hops about on the snow below, gleaning the seeds 

 that fall. This species follows the Juncos into weedy vege- 

 table gardens, and flocks about farms and haystacks to pick 

 up seeds. The Tree Sparrows are among the few birds 

 that can "look our winters in the face and sing." They 

 are occasionally heard singing in November and December
