I think most of the big owls have a fairly wide prey range, and I'll bet
(and there is evidence to support it) that smaller owls are taken whenever
they are encountered. I don't think they are the major prey for any of the
larger species, just because small mammals (which, after all, are the prey
of the small owls too) are much more abundant and probably easier to catch.

I have a couple of times attracted western screech-owls by whistling their
calls, then, after they were nearby and responding vigorously, would shut
them up instantly by giving a single great horned owl hoot. I have to add
that on other occasions the horned owl call had no effect. Did your
screech-owls shut up when the barred appeared?
