Dr. Townsend is said to have found this Owl in Oregon, Dr. Gambel met with it in California, Mr. Audubon has taken it both in Kentucky and in Louisiana, Mr. Wilson met with it in New Jersey, Mr. McCulloch in Nova Scotia, and Dr. Hoy in Wisconsin. Dr. Newberry met with this bird in Oregon, but saw none in California. Dr. Suckley obtained it at the Dalles, on the north side of the Columbia, in December. This was several miles from the timbered region, and the bird was supposed to be living in the basaltic cliffs of the vicinity. Dr. Cooper found one at Vancouver in February. It was dead, and had apparently died of starvation. Professor Snow speaks of it as rare in Kansas. Mr. Boardman and Professor Verrill both give it as resident and as common in Maine. It is rather occasional and rare in Eastern Massachusetts, and Mr. Allen did not find it common near Springfield. On one occasion I found one of these birds in April, at Nahant. It was apparently migrating, and had sought shelter in the rocky cliffs of that peninsula. It was greatly bewildered by the light, and was several times almost on the point of being captured by hand. This Owl is not unfrequently kept in confinement. It seems easily reconciled to captivity, becomes quite tame, suffers itself to be handled by strangers without resenting the familiarity, but is greatly excited at the sight of mice or rats. Captain Bland had one of these birds in captivity at Halifax, which he put into the same room with a rat. The bird immediately attacked and killed the rat, but died soon after of exhaustion. The notes of this Owl, during the breeding-season, are said to resemble the noise made by the filing of a saw, and it is known in certain localities as the Saw-Whet. Mr. Audubon, on one occasion, hearing these notes in a forest, and unaware of their source, imagined he was in the vicinity of a saw-mill.
