NESTS AND NEST-BUILDING IN BIRDS 



267 



One rod distant from the tree stood a number of white pines, 

 and their withered needles littered the ground all about, while 

 at thrice this distance in another direction a grape climbed into 

 an apple tree. It is possible that discovery of the vine in the 

 first instance immediately awakened in this individual the build- 

 ing responses, and decided in favor of the bast; at least the 

 case of the cedar waxwing, which is typical of many others. 



Figure 12 — Sectional view of nest shown in figure 11 and drawn to the same scale, 

 to show form and symmetry of cup, and relation of entire nest to support. 



points to this conclusion. In nests of the vireo from northern 

 Ohio, w^here the white pine is but rarely if ever found growing 

 under natural conditions (compare nest No. 3, table III) the bast 

 habit seems to prevail. 



In line with the maple referred to above stands a larch, in 

 which a cedar bird built a neat nest; this was wholly framed 

 of the dead brittle twigs of the tree and lined with pine needles, 

 all having been evidently gathered from the ground below.
