Wilsonia pusilla. Maine (Lake Umbagog). color ① 1872. June 2-5 P perhaps half a dozen specimens in log-heaps and thickets along wood edges; none seen after June 5. 1873. Aug. 23. Shot a young female in perfect fall plumage among the alders on the banks of Cambridge River about three miles above the dam. It was in a mixed flock of Warbler and probably came from further north, although I have no- ticed no indications as yet, of any migration. 1879. May 25. A single male with other Warblers in the plum orchard " 27. A male in full song on a clump of firs on a hill- side pasture. " 28. color ② //A male singing loudly and steadily in the plum or- chard in the garden early this morning. The song is very like that of the Nashville Warbler, but less flowing and more abrupt, in fact almost explosive in character. It seemed to cost the bird a strong effort to produce it. 1880. May 31. A male singing. 1881. May 21. Shot a pair in a clump of willows, in a bog behind the house.
