266 Influence of Harvest-time. 



six, or more, calling to each other in their happy 

 confidential way. On that day the trees and hedges 

 seemed to become quite populous again with finches. 

 The sparrows, too, were busy in the roads once 

 more. For a week previously every now and then 

 a single lark might be heard singing for a few min-

 a second spring : at the same time a few buttercups 

 bloomed, to add to the illusion. 



This migration of the finches from the hedgerows 

 out into the fields, and their coming back, is very 

 striking. It may possibly be connected with the 

 phenomenon of ' packing ; ' for they seem to go away 

 by twos and threes, to disappear gradually, but to 

 return almost all at once, and in parties or flocks. 

 The number in the flocks varies a great deal : it is 

 a common opinion that it depends on the weather, 

 and that in hard winters, when the cold is severe 

 and prolonged, the flocks are much larger. Wood- 

 pigeons are seldom, it is said, seen in great flocks 

 till the winter is advanced. 



Has the date of the harvest any influence upon the 

 migration of birds? The harvest in some counties

 time they have mown the grass or reaped the wheat, 

 as the case may be, in one county, the crops are ripe 

 in another, to which they then wend their way. 



One of the very earliest counties, perhaps, is
