It quite interesting, infuriating at times, that humans have caused this problem of over populated low level predators. We have eliminated the natural predators (coyotes, bobcats, mountain lions, wolves) and allowed the population of coon type animals to explode.
Odd as it may seem, urban and suburban environments can (and do) support higher populations of various animals than rural habitats can and do.
Raccoons, rabbits, and squirrels have much higher population densities in the cities around here than can be found "out in the country".
So much higher, in fact, that I often take my raptors into the cities to hunt, even though I live 40 miles out into the country. If I'm hunting rabbits, I can get only 3-4 flushes in the country areas, in the same time that I can get a dozen or more flushes in an industrial park or a small grassy/wooded section between two businesses. The same thing can be said for squirrels and crows (depending upon which type of raptor I'm hunting with). It's easily worth my time to drive into an industrial area, even though I literally live within a 400 acre Boy Scout camp out in the sticks. I can't do as well hunting in the camp as I can in the city. Who'da thunk it?
Interestingly, coyotes are another animal that can enjoy a higher population density within an urban area than they can out in the sticks (and trust me, we have plenty of them out here too).
There are some interesting dynamics at play in urban settings, that allow for these high densities. For one, park and set-aside green zones are often planted with nut-bearing trees (oaks, etc) as well as maples which provide great food for squirrels and rabbits. The urban areas are also divided into handy "territories" defined by semi-uncrossable barriers (highways, busy roads, rivers, etc) that keep neighboring animal populations from directly competing (and spreading disease). Lots of places to shack up too (under porches, foundations, etc) many of which are practically "ready-made". In addition, people leave TONS of food readily available for wildlife- bird feeders, dog and cat bowls, gardens and various plantings (even comparatively succulent grass on the lawns). And don't forget the garbage as a food source- dumpsters, bags, and even "distributed" food alongside the various roadways...
Omnivores like raccoons and coyotes have it made! All that readily-available food in addition to the higher populations of prey animals...
