marshall, 1939 Othus flammeolus Yosemite, June 20 conflict - territorial or other- wise. The remaining 7, probably the 1st, still followed me about very gladly & perched in opposed places. I built a fire & Woody & I left an hour or so - then tried to call up the owls again - but with no fortune success. Next walked down trail about a mile & arrived at dense forest of tall firs on the slopes surrounding a wet narrow meadow along a slow stream. Called up 3 Ot's in succession. All hooting in unison & came near each other, then spread out again & 2 stopped calling somewhat later. A great diff. in pitch - intervals me sol, la, respectively. I followed the nearest Ot, which had the low voice.
