Marshall,1938 Otus flammeolus Whitakers Forest June 22 - outlined by facial disks.Wide- eyed & alert expression from dominant features, the large,brown eyes,large white tufts extending up from cere. Low-voiced male followed 75 yd.S. to cedar where sat in axil limb, 10 ft. up. Was unusual in that squatted on perch with feathers fluffed out & wings relaxed. Obviously a re sting pose, didn't look about for insect, remained quite still,giving low, soft hoots involving only slight body contraction.However, noticeable feature of hooting was expansion of sides of throat - feathers would part due to expansion & show the apterium on each side of neck. Both males of much less intensity of voice than the full-voiced bird heard on 20th. Meadows Flat, 5000 ft., W.

I passed through, namely, the one 100 yd. W Sequoi Ranger Station, and the one with the most uphill terr. ab by the road S Meadows flat. (This is the terr. just E of where male #431 was collect- ed.)

June 27 At dusk, at Terr. NW corner property, attempted to call up the two pairs usually there Got several very faint hoots in reply from male up hill from road.Soon stopped.
