Nyctala acadica. Lake Umbagog, Maine. 1896. At 9 P.M. as I was writing in our open camp a Saw-whet June 4. began filing in the birch grove within 50 yards or less of where I was sitting. The air was perfectly still and I heard him to good advantage. There was positively no ringing or other metallic quality to the notes at this distance. They were simply so many whistles very similar in quality to those of Glaucidium (the Trinidad species) but rather more guttural and each with a "double-tongued" form - whur'dle-whur'dle, I should write them. Evidently the resemblance (slight at best) to saw filing is lost when one is at all near the bird. When it is very far away (as I have proved by direct compari- son on several evenings this seasons) its call is very simi- lar to that of Pickering's Hyla.
