Dendroica caerulescens. copy D Lake Umbagog, Maine. Nests. 1897. All three of the nests of Dendroica caerulescens which I June 11. examined to-day on Great Island were in beds of yew a few rods from the Lake shore. One was in short, rather scanty yew a- bout 8 inches above the ground, another in dense, taller yew about a foot above the ground, the third in excessively rank yew waist high but the nest not over 15 inches above the ground. Two nests were near large, prostrate logs. All three birds were sitting. Two flew from the nest at a distance of eight or ten yards in advance of us and one of them would not return to her eggs while my camera was in position about 6 ft. away although I left it there for over an hour. The third bird sat more closely than any female of this species that I have hitherto seen. Watrous struck the yew within six inches of her with his stick without starting her. Later I set up my camera first about six feet away, then four feet, and finally within two and one half feet using the focusing cloth each time and taking six pictures in all. When the tripod leg shook the branch which supported the nest the bird would raise her head and crane her neck out over the edge of the nest to get a better view of me. At all other times she sat very still merely winking at short regular intervals. My photographs show her position in the nest well. When I had finished my work I packed up my camera and left the bird still sitting on 58
