Habits. — Tlie Black-throated Green Warbler, like nearly all the mem- 

 bers of this liighly interesting genus, has, to ti very great degree, escaped tiie 

 closer ol)servatioiis of our older ornitliologi.sts. Wilson only noticed it as it 

 passed through renn.sylvania in its eaily s])ring migrations. He mentions its 

 freiiuenting the higher Iminches of forest trees in search ol' tlie Itirvic of the
