Dendroica castanea. Maine (Lake Umbagog). 1879. May 24. About six of both sexes, apparently not paired. Males singing. copy ③ June 1. // This species, like the Cape May and Tennessee War- blers, seems to have entirely deserted this region. At least those seen near the Lake House May 26 have disap- peared. Yesterday I visited a spot where they abounded in 1876, but not one could be found, nor was it either seen or heard during my trip up Cambridge River, May 29. // " 3. A male singing on B Point. Dendroeca castanea. Maine (Lake Umbagog). copy ④ 1879. (June 18) // A male singing on Great Island. The song is a simple zoo-zoo-zoo, very quickly given. It closely re- sombles the ordinary note of Regulus satrapa but has a more ringing quality. There also I think, one or two pairs breeding west of the Peaslee Farm, but I know of none elsewhere and the bird is decidedly rare here this season. // 1880. May 16. Numbers seen to-day. 1881. May 19. Several in the woods near the middle dam.. 1876. May 31. Hoard a number singing. The song is very uniform in different individuals, and is almost indistinguisha- ble from the feebler variation of the Redstart. It also resembles the tzee, tzee, tzee of Regulus satrapa.
