Marshall,1938 Otus flammeolus Meadows Flat,June 12. then from sm. branch near-te in interior young ponderosa pind; there shot - #432, male. Like the others it frequentted a large black oak with- in its terr., & unlike them,its compound call consisted of only 2 syll.: boot,boop;etc.midnight On way back to Whitakers, another male heard above rd. at W. side Sequoia Ranger Sta Station meadow.May or may not have been that heard back of the station on June 10. Whitakers Forest June 13 Arrived at territory owls at end rd. at NW boundary.Male already hooting,& a Glaucidium whistling to S. Gl. soon stopped and Otus continued. Series of gurgling hoots given in flight as if in pursuit of female. Several times heard slight mew- ing or whining cries at higher pitch than male & with prolonged downward inflection. These, I hope to prove,are made by the female. June 15 Same place, but earlier,just at sund down . Male hooted several times while still very light .Followed sound & found him sitting in densest part clump firs & 6' off gn&. Sat still,resembled Screech Owls who come from hi hiding places & sit in shade untill dark enough to forage. This owl,however . soon began to fly about,into the higher trees & calling stopped. At this time the Glaucidium began calling close at hand & continued , causing extended silence on pt. Otus. Otus still there, answered softly my calls several times.(SEe under Glaucidium) Glaucidium apparently the dominant bird. June 20 One heard at 9:30PM just across rd. from Cedar Cabin, within game refuge, & within former terr. of #377. Heard at same time female Srix was baying near pool. I tried to approach the owl,but it ,like #377,kept always ahead & almost beyond audibility.Probably because was outside own terr.& driven back by my hoots.
