Dendroica æstiva copy (1) 1894. September // In a large mixed flock of Warblers which were feeding in the tops of the birches on Pini Point this morning I found a Yellow Warbler—a rare bird here. It was pure, rich yellow beneath without obvious traces of the characteristic streaking. I had a clear view of it at short range & watched it for two minutes or more. copy (2) 1907 July 26 ½ // I heard this bird sing eight or ten times about 4 P.M. as I was sitting by an open window in my room at Balsair. It was at a considerable distance—apparently in the bushery by the creek shore in the direction of Mac Sweets'—yet I got all the notes distinctly if faintly—excluding the Terminal ones which distinguish its song from that of D. pennsylvanica. I am sure that I made no mistake, Mr. J. Bernard Walton, a young bird student from Pennsylvania who is staying here, tells me that he saw a & Yellow Warbler & heard its song about ten days ago. This bird was in a bush by the roadside near Sweets' house and very probably the same individual that I noted to-day.
