Marshall, 1939 47. Otus flammeolus Yosemite, July 20, 1939 open country & could be seen easily by moonlight or flashlight as it flew swiftly directly & low (10') over the open places. Its eyeshine also could be seen for a good distance. It was moving around more than usual; that is, it would not stay long in any one perch. (The bird all this time had never perched near enough for a shot.) It was seen for a moment in a solitary dead pine then it called from a dense juniper. I gave Spotted Owl calls hoping to cause the owl to 'stay put'. It became immediately silent, but I could not see it anywhere in the 20' juniper. After ½ mi. the trail again entered a fine open forest of large red firs on sloping ground. A ? was heard a long distance away & was not called in.
