Wilson (1822) discovered this interesting warbler in Connecticut, 

 described it, and named it for the State in which he first found it. He 

 gave it the specific name agills., because it "seemed more than com- 

 monly active, not remaining for a moment in the same position." Both 

 names now seem inappropriate, for Connecticut is far from either its 

 breeding range or its winter home ; furthermore, recent studies of its 

 habits show that it is not necessarily "more than commonly active", as 

 it often remains perched for considerable periods.
