My 32" dish still has a cutoff shelf above most owls.
My ME-67 performed well at low frequencies but was not very
directional for owls. It was good at droping the gain of higher
pitches off axis. It worked best at reduction of off axis frog and
insect chorus when recording owls but was poor at determination of
the exact direction of the owl. In fact I had to not wear headphones
when recording owls with my shotgun so that I would not go the wrong
direction.
I recently used my "football on a stick" for Great Gray Owl and Saw-
whet Owls and was very happy with the result but I was not trying to
eliminate anything else off axis and was just looking for sensitivity.
