We don’t seem to have foxes in L.A. (although they have been seen - by myself among others - on the campus of the university at which I work, so that’s not wholly true) but we do have coyotes! In any case none of our ravens are kept with clipped wings in any historical buildings, so if and when they contend with coyotes remains to be seen.
Racoons, possum and skunk, all nocturnal, are the big L.A. urban game now, and of course deer live in all the local mountains - you can see them below the Hollywood sign, for instance, but they don’t actually live all over the city the way the nocturnal three do.
More celebration of the Tower ravens here, with some quite good photos.
