Vireo philadelphicus. Maine (Lake Umbagog). 1879. June 21. Two males singing—one in birches bordering Cam- bridge River above the mill, the other on B Point. I can now readily distinguish the song from that of the Red-eye. It has two high notes followed by two lower ones.. There are, however, occasionally interpolations identical both in tone and pitch with some of the notes of the Red-eye. " 22. Male singing near the house. " 23. Thoroughly identified a male which was singing in a willow in the Lake House garden. " 24. A male singing at Nowry about five miles north of Bethel. 1880. May 31. Heard and saw several. June 3. Three males singing yesterday; the song is slower than that of V.olivaceous.
