Vireo gilvus. Lake Umbagog, Maine. 1896. Aug. 14. I shot a Warbling Vireo this morning in the Balm O'Gile- ad Poplar at the N.W. corner of the piazza firing from the window of my room. There were certainly three and I think four of these Vireos in the tree. I first saw them when I was dressing and heard them call and one of the young warble in low tones. This is the first time that I have ever found V.gilvus at Umbagog although it breeds regularly at Bethel.
