The Mourning Dove definitely sounded owl-like to me.
In my area, the calls of the Barred Owl and Eurasian Collared-Dove are often confused. Both are relatively recent arrivals in the region.
Despite their mysterious reputation, the lives of owls are more similar, than different, to other familiar birds, especially cavity nesters. Possible exceptions are owls "superpowers", or adaptations for hunting at night, as most species are nocturnal. Also, young owls seem to leave the nest fairly early, so they are able to "branch" into nearby trees, for protection from possible predators.
I was not surprised that large owls, such as the Cape Eagle-Owl and the Powerful Owl hunted mammals rather than smaller prey, but I was surprised that a small owl, such as the Northern Pygmy-Owl, was a skilled predator of birds and small mammals.
This incident did not happen to me, but was recently reported in our local media.
A homeowner in an upscale suburb of Victoria B.C. called police around 4 a.m. to report an intruder in their home. When the police arrived, they located the suspect, a Barred Owl, perched on a couch. After some coaxing, the "suspect" exited without further incident, through open patio doors.
Although Barred Owls are a recent arrival to southwestern B.C. (around 1970), they are now a common resident in the area. I have often seen them perched in trees during daylight hours, although they are mostly nocturnal.
