To me, Foxes are one of those magical, sneaky creatures that you should feel lucky to catch a glimpse of. They are small predators and will hardly make a dent in your bird populations, IMO. Please don't trap and kill them inhumanely unless you know for a FACT that they are eating your livestock or causing other specific issues.
Over in southern Michigan, our wild animal populations are changing also. The explosion of deer is a real problem lately. On my 13 mile commute to work through semi-rural/suburban areas, I pass at least a dozen dead deer laying on the side of the road (why does no one pick them up anymore?) and it seems a new one gets hit almost every day by some unlucky driver.
Coyote pack seems stable in my area, they come down into my block about every other week and howl and sing as the amtrack train honks it's way through town.
Mink are thriving in all the waterways here too.
