We also have bobcats around here, Chris. The thing that steered me
away from owls was (1) I'd never heard an owl like that and (2) it has
some pretty low freq material around 170Hz. While I've recorded baby
vulture vox down to around 140Hz, it's a bit unusual, but I suspect it
is an avian call of some kind. I just can't imagine what given the
bird mix around these here parts.
