Audubon discovered the young of this species near Lake Cayuga and Lake Champlain. I 
have not been able to procure a specimen in this State, except of the young from a few miles 
above the city. Feeds on small insects and berries. I do not know by whom the two nomi¬ 
nal species were first clearly shown to be one, but the first indication is to be found in the 
Comparative List of Bonaparte. The Hemlock Warbler, as its name indicates, is most 
commonly found in forests, and extends its migrations from the Mississippi to the 52d degree 
of north latitude.
