Habits. — The IJlack-throated Green AVarhler, like nearly all the mem- 

 bers of this hiohly interesting genus, has, t(j a very great degree, escaped the 

 closer observations of our older ornithologists. Wilson only noticed it as it 

 passed through rciinsylvania in its early spring migrations. He mentions its 

 fre([uenting the higher branches of forest trees in search of the larvje of the 

 smaller insects that feed upon the oi)ening buds, and describes it as a lively,
