Lake Umbagog. 1909. June 10. (no.3) In the woods traversed this morning I could find no yew what—Black-throated-Blue Warblers. ever. It has all been eaten by the deer I suppose. In view of its apparent total absence I was surprised to note so many Black-throated-Blue Warblers. I wonder where they can have their nests. I heard them singing in places where there almost no evergreens of any kind. One had a peculiar song consisting of two notes only, both on the same key—wree-wree I wrote it in my note book.
