Nuttallornis borealis. Maine (Lake Umbagog). 1880. May 20. Sevoral. June 11. A newly finished nest in a spruce. The old birds dove down about my climber's head although the nest was empty. " 14. Set C-4. Incubated four days; horizontal branch of tall, slender spruce, near extremity and about four feet from the trunk; height forty feet; female sitting. As we landed near the spot she left the nest and joined her mate, both birds uttering their anxious pill-pill- pill. Upon our withdrawing a little distance she re- turned to the nest, again leaving it when my guide began to climb the tree. Neither of these birds came very near while he was taking the eggs. S. Elwyn B. Evans. " 16. Set D-3. Incubated three days; near extremity of horizontal branch of black spruce, eight feet from trunk; height twenty-five feet; female sitting; she flew off when we rapped on the tree and alighted on a dead branch near sat in perfect silence while we took the nest and eggs. The male did not appear and I have seldom heard him near this nest which was immediately behind the Lake House. " " Set E-3. Fresh--extremity of short horizontal branch of exceedingly tall black spruce, three feet from trunk; height forty-five feet; female sitting; when my guide ascended the tree both she and the male swooped about his head "snapping their teeth". Point east of Stone farm. " 19. Set F-3. Fresh--near extremity of horizontal branch of black spruce, midway between ground and top of tree which was a tall slender one; height twenty feet; fe- male sitting; we rapped sharply on the tree without starting her nor did she leave the nest till my guide had nearly reached it. She then flew to an adjoining tree where, with the male, she kept calling pill-pill-pill, but neither bird plunged about the climber's head nor snapped their bills. 1881. May 14. Saw five, the first. 59
