Perhaps a juvenile rabbit? This was likely not an owl kill - they
preferentially eat the head.

One wouldn't describe the claws of a SW Owl as being "heavy and gnarly".
Perhaps it was a larger owl...GH Owls can take any of the others.


Do they mate at this time of the year rather than the spring?


Nope. Any hooting/tooting you're hearing now is likely territorial, or
perhaps to maintain a pair bond for the residents. Mating calls tend to
start in February-March.

Is that why I am hearing the calling or are they gregarious ...


A few species are gregarious in winter, the Long/Short Eared Owls are best
known for this. In several presentations at the recent World Owl Conference,
people showed photos of communal roosts of Long-eared Owls...*in* towns,
often in deciduous trees. You can imagine the number of droppings and
pellets that 30 LE Owls in one tree could drop! This creates just as much
animosity for these owls as pigeons do in our downtowns. Education seems to
be working though.
