HABITS. The Short-eared Owl appears to be distributed, in varying frequency, throughout North America, more abundant in the Arctic regions during the summer, and more frequently met with in the United States during the winter months. Richardson met with it throughout the fur countries as far to the north as the 67th parallel. Professor Holböll gives it as a bird of Greenland, and it was met with in considerable abundance by MacFarlane in the Anderson River district. Mr. Murray mentions a specimen received from the wooded district between Hudson’s Bay and Lake Winnipeg. Captain Blakiston met with it on the coast of Hudson’s Bay, and Mr. Bernard Ross on the Mackenzie River. Mr. Dresser speaks of it as common at times near San Antonio during the winter months, keeping itself in the tall weeds and grass. It is given by Dr. Gundlach as an occasional visitant of Cuba. Dr. Newberry met with it throughout Oregon and California, and found it especially common in the Klamath Basin. On the level meadow-like prairies of the Upper Pitt River it was seen associating with the Marsh Hawk in considerable numbers. It was generally concealed in the grass, and rose as the party approached. He afterwards met with this bird on the shores of Klamath Lake, and in the Des Chutes Basin, among grass and sage-bushes, in those localities associated with the Burrowing Owl (_A. hypogæa_). In Washington Territory it was found by Dr. Cooper on the great Spokane Plain, where, as elsewhere, it was commonly found in the long grass during the day. In fall and winter it appeared in large numbers on the low prairies of the coast, but was not gregarious. Though properly nocturnal, it was met with, hunting on cloudy days, flying low over the meadows, in the manner of the Marsh Hawk. He did not meet with it in summer in the Territory.
