THE SIMPLE AET OF SAPSUCKING 



THE yellow-bellied sap sucker is, at this time

 peckers, and in its life we have an excellent 

 example of that individuality which is ever crop-

 life under new conditions. 



In the spring we tap the sugar maples, and 

 gather great pailf uls of the sap as it rises from its 

 winter resting-place in the roots, and the sap- 

 sucker likes to steal from our pails or to tap the 

 trees for himself. But throughout part of the 

 year he is satisfied with an insect diet and chooses 

 the time when the sap begins to flow downward 

 in the autumn for committing his most serious 

 depredations upon the tree. It was formerly 

 thought that this bird, like its near relatives, the 

 downy and hairy woodpeckers, was forever bor-

 for several feet up and down its trunk by these
