Nywale acacica. Maine {Lake Umbagog}. 1879. June 16. While forcing my way through a dense arbor-vitae swamp bordering Cambridge River a short distance above the mill, a beautiful little adult of this species start- ed from a branch within three feet of my head and after flying about ten paces alighted again. Having no gun with me I tried to approach near enough to knock him down with a pole but he proved much too shy for this; starting again and taking another short flight he settled on a higher branch and before I could get beneath him again flew and disappeared. The afternoon was dark and gloomy and it was raining hard at the time. His motions were animated and he apparently saw distinctly. His flight was noiseless and essentially Owl-like. I noticed that he alighted in the abrupt way peculiar to birds in this family. There were many Warblers and other small birds within a few yards of him but none of them made any fuss or appeared to notice him in the least. 1880. May 16. One calling this forenoon in the forest bordering the lake-shore. His notes exactly resembled the sounds produced by filing a saw: shreigh-aw, shreigh-aw, shreigh- shreigh-aw, shreigh-aw. Alva Coolidge says they are heard everywhere throughout the woods in February and March, especially the latter month. They sing at night, but most frequently just before day-break. They are sometimes heard in the daytime during cloudy weath- er and their notes are thought to forbode rain. He tells me that he has seen the Owl in the act of making the sound, but the majority of the guides and lumbermen believe that it is uttered by a rabbit (Lepus americanus) while a few refer it to the Striped Squirrel.
