Dendroica castanea. Lake Umbagog, Maine. Nests. 1897. bird does when soliciting or receiving food. June 14. Returning to the boats we pulled out of the cove and alon (No.2). the shore eastward. xxxx Watrous exclaimed (after we had landed and found an empty Swainson's Thrush's nest) "There is a Warbler's nest"! and looking up I saw it at once, almost over our heads. It was in a red spruce (a tree about 40 feet tall and 10 inches in diameter at the base of the trunk) on a stout, horizontal branch 11 feet from the main stem, 3 feet from the extremity of the branch, and 25 feet above the ground. On climbing the tree to a point well above the nest Watrous reported that he could see at least four eggs. A male Bay- breasted Warbler was singing not 20 yards off and twice he came into the tree and flitted about near the nest showing evident interest in it. It is possible that we disturbed and frightened off the female while we were talking the Thrush's nest but more probable that she was away feeding. At all e- vents we saw nothing of her on this occasion and for this rea- son left the nest undisturbed although there can be no reason- able doubt that it is a Bay-breast's. (Watrous and Gilbert visited this nest again on June and took it with a set of 5 eggs. The female was sitting and Watrous had a good view of her). 109
