i66 Bird- Lore 



month may open frosty for the purpose of making excuse to close like 

 August, or it may open truly summer-like and close in a flurry of snow. 

 There are not seldom a few days of cold rainy weather near the tenth 

 followed by as fine an Indian summer as heart could desire. Whatever 

 the weather may be, some birds are certain to move southward during the 

 first ten days, and others are as certain to leave us during the last ten 

 days, but the exact time in either caseDcannot be foretold, because the 

 weather cannot be foretold. During this month, weather is a prime 

 factor in the movements of the birds. 



November is pretty certain to bring us the first snow of any conse- 

 quence. It rarely comes before the last week, or if it does come earlier 

 the month is pretty certain to close in brown apparel because of the rains 

 which follow. We may have snow during the first week, to be sure, 

 but if so it soon disappears, and is a forecast of a warm December. The 

 weather is seldom severe, the temperature rarely falling as low as 20 . 

 Of course the birds are greatly influenced by November weather. The. 

 snow storm of the last week drives nearly all of the strictly migratory 

 species south and greatly reduces the numbers of many that remain dur- 

 ing the winter, but it is rarely severe enough to bring us many of the more 

 hardy northern birds which spend January with us.
