This is probably (almost surely is) natural "song" but there's a possibility I'd hooted an imitation. Quality: 2+. Level: +5.
After playback of above the owl was silent for ~ 10 min. The last two phrases are after the owl began to sing again. Quality: 2+. Level: +5.
Note: By error I had the Bass-1 filter in the circuit for all but the last phrase.
Note: Playback of last two phrases apparently caused(?) the owl to leave the area.
Parabola pointed at sky, not at bird. 139 tape. Std.
