'Ventriloquism' is defined as, "The art or practice of speaking or
producing sounds in such a manner that the voice appears to proceed from
some person or object other than the speaker, and usually at some
distance from him." Since the owl(s) did just that, case closed. It's
ventriloquism.
I believe there was once a saying popular in these parts:
"Microphones are not ears, Loudspeakers are not birds, A listening room
is not nature." A parabola hears things differently from humans and
others with organic stereo sound interpretation systems, but then birds
generally have less to fear from parabolas.
