Nyctala acadica. Lake Umbagog, Maine. 1896. Charlie Tidswell who is with the river drivers at Moll's May 25. Rock called on us this evening. He says that an Acadian Owl has been whetting his saw near the spring among the hemlocks back of the rock these past three nights keeping it up all night at intervals. Jim and he heard one twice on Pine Point before the subject came up. Jim thought it was very near the camp. I was sitting inside and missed it, much to my chagrin. May 27. This evening the Saw-whet Owl at Moll's Rock began filing and kept it up without the slightest cessation for two or three minutes. We could hear him distinctly but faintly al- thought the distance is nearly if not quite 1 1/2 miles. The air, of course, was perfectly still at the time. The call re- minded me of that of Glaucidium (the Trinidad species) but it was more metallic in quality and infinitely more prolonged - that is to say there were very many more repetitions of the note, probably over 100 for they were given at the rate of a- bout four every five seconds. I am now conscious of having heard this sound nearly every evening since we came here but of having mistaken it for that of the grating of the metallic drop rudder of my sailing canoe. Indeed when heard at this distance it very closely resembles the clanking of a piece of tin against other metal. 33
