Gexkkal Habits. In studying animal life, one of the 

 first lessons which we learn is, that certain species inhabit 

 particular sections of country, avoiding other sections, which 

 are in turn in]labit^id by other species. Birds offer no excep- 

 tion to this rule, hence w^e find that the different species of 

 warblers are apt to select certain kinds of woodlands. Thus 

 the Black-thoated Greens are almost always found amono- 

 white pines, and the larger the trees and more extended the 

 grjves, the more are they frequented by tr ese beautiful little 

 w.irblers. As high white pines usually have thick foliage, in

 these warblers may be clashed among those birds which are 

 more often heard than seen. Sometimes, however, especially

 ing material, when the males are apt to accompany them, these 

 warblers will descend into low trees, where their trim, slender 

 forms and bright colors may be seen. Thev are ciuite active 

 warblers, usually moving quickly from place to place, but like 

 many birds, even the most active, they find time to rest, and 

 then sit perfectly quiet. Their resting time is often during 

 the heat of the day, when the insect larva, which forms the 

 chief portion of their diet, are not feeding. These mid-day si-
