Marshall, 1939 Otus flammeolus Village, South Rim Grand Canyon, Co. Ariz. July 19, 1939 pitched yapping cries, not musical notes - like rick- rick-rick- about 3 or 4; very similar to low daybreak cries of Otus asio. May have been female - proper pitch. I gave spotted owl hoots & it was silenced - sat still. No sound from ♀. After 15 min I hooted (O. f.) again & it hooted again. He at length came low down in the tree when I watched him at close range as he sat on bare horiz branch & next to trunk. Fluffed out feathers with gt energy & voice. Stopped hooting & would look at me otherI squawked. Sitting at about 50-60° L. Heard again the ♀(?) cries. It moved & galled in tree 3Dyd. away. I followed it as I attempted to locate him, heard wings chick on twigs in yellow pine
