Marshall, 1939 Otus flammeolus 31. Flag - June 2 softly and only 1-5 notes every few min. I tried moving around - succeeded in getting him excited - followed me - gave protest breathy hoots: boot-op, bootle - an interval of a major 3rd between 2 grace notes & main hoot - than slighter yet distinct slur down again (1 major 3rd) on last syllable. Daws him fly into oo pines 30' high / (upper parts) then got him into the low bare branches of a similar pine within a rather dense clump. (flight preceded by clattering of twigs which his wings would hit on the takeoff.) Sat far out on dead horiz. twig (protected by clump) and about 4' above my head. Sat very still & silent while I moved under him & hooted. Looked at the light. Jerked
