WINTER BIRDS. 



BY LYNDS JONES. 



The latitudinal variation in the range of many species of 

 birds in winter is one of the problems which nothing but 

 careful and persistent field work will solve. Sufficient in- 

 terest attaches to the study to make the effort of deter- 

 mining what birds are about us in winter well worth the 

 while. Bird studies in winter are not so hedged about with 

 difficulties and inconveniences as study in August, because 

 then dense foliage, excessive heat, insects and the timidity 

 of the birds combine to thwart the purposes of the bird stu- 

 dent. In winter there is only the cold and snow, which 

 should not be serious hindrances to a healthy body.
