Marshall, 1939 Otus flammeolus Flagstaff, Ariz.; June 2. Time. Would answer my hoots with soft notes if I moved from place to place often enough. Would often come very close to answer although I never saw him. He perched sometimes in open-branched high yellow pines, often in dense groves of sapling pine, and in black oaks. I walked up the canyon which was now, very narrow & choked with small pines, and the Ot was silent! About 75 yards farther, a O answered, may have been same one. Called very faringly & very softly - only single hoots. I followed it up the N side of the canyon & tried to see it as it called fairly steadily (as long as I answered from time to time) from a black oak. I circled the oak (among small pines)
